The SIRIUS Stiletto 100 offers reception of a live SIRIUS signal on the go, plus up to an amazing 100 hours of content storage. It offers a beautiful display and easy-to-use controls, comes with a slew of useful accessories, and works with optional accessories that expand the number of places and ways you can listen to SIRIUS.

True portability
The Stiletto features a built-in antenna that can receive live SIRIUS broadcasts, without having to be docked in either of its optional car or home cradles. Just charge up the battery, slip on the pair of included earbuds, and you've got a great companion if you're out jogging, hiking, or just walking around town.

You'll also get a set of headphones with an antenna built into the headband for better reception in areas where the signal tends to get blocked. Using these headphones also keeps your body from blocking the SIRIUS signal.

Storage galore
The Stiletto lets you store up to 100 hours of SIRIUS songs and programming. And up to just about half of the memory can be used to store your MP3 and WMA files, too — keep in mind that you won't get a full 50 hours of MP3s and WMAs because of file size.

You can record SIRIUS programming in blocks of up to six hours each, and you can schedule up to 100 recordings in advance. Then just combine your favorite SIRIUS content with your MP3s and WMAs for a spectacular playlist.

WiFi™ capability
Sometimes you'll find spots where you can't get SIRIUS reception, but this doesn't necessarily mean that you can't hear live SIRIUS broadcasts. If you're in range of an accessible WiFi network, use the Stiletto to access the SIRIUS website and stream all of SIRIUS' music channels, Howard Stern, and more. You'll also make fewer demands on the battery, more than doubling its playback time, compared to listening to live SIRIUS in standard portable mode.

Lots of goodies in the box
In addition to the earbuds and headphones with built-in antenna, you'll get two batteries: one standard and one extended-life, which offers up to four hours of live SIRIUS reception, 8 hours in WiFi mode, and 20 hours of stored-content playback. You'll also get an indoor power adapter, so you can recharge the batteries.

Extra accessories
To play the Stiletto over your car stereo, you'll need to get the optional car kit. It includes an antenna, a power adapter, and a mounting cradle with 10 buttons that let you save up to 30 channel presets. You can connect the cradle to your stereo's auxiliary input, or use the wireless FM transmitter to play the sound over any unused FM frequency.*

Want to play the Stiletto through your home stereo? Pick up the optional home kit. Its dock charges both Stiletto batteries at the same time, and it also uses an FM transmitter to play the sound over any FM radio. And soon, you'll be able to use the Stiletto in your home or office with a compatible powered speaker system.

Note: A subscription to SIRIUS is also required. Satellite radio service is available only within Canada and the lower 48 states — not available in Hawaii or U.S. territories. Limited service is available in Alaska. Portable reception may vary by location. If you have questions about the proposed XM/SIRIUS merger, read the SIRIUS guarantee.

*Important note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna. SIRIUS includes an FM extender cable in order to address this issue, but Crutchfield strongly encourages customers to use an auxiliary input, wired FM modulator, or cassette adapter to ensure your satisfaction with the performance and cosmetics of this satellite radio.

SIRIUS Stiletto 100

Crutchfield Customer Review (What's this?)

The key to making this product work is to remove the battery every half hour and reboot it. After that it will work great until it overheats and you have to it reboot again. Remeber dont just try turning it off and on, you must remove the battery and hold it for a few seconds then reassemble the unit.

The garage that designed this product als forgot to include a back button, but if you memorize all 200 hundred channels you should be okay.

Nice but not great

Crutchfield Customer Review (What's this?)

So I picked this up because my GF didn't have a unit in her car and since it was a lease I didn't want to put in a new stereo system. If you're outside and you're using it as a portable device it's not too bad. Don't sit under any trees. It works fine in open areas (My Deck, in town, large parks). I bought the car kit and set it up and even used the additional FM booster they send with the kit and it's still as scratchy as they come even when I'm driving down the turnpike or GSP. A few times we've had to power it down completely, remove it from the dock and put it back then turn it on to get it to play through an FM station. Granted I know it won't get the signal quality I get from my built-in DVD unit (Pioneer AVIC-D) but it shouldn't be this tough to get a decent signal. Swap out the headphones too. The ones they send you with the built in antenna make you look like you're wearing a halo around your head.

Crutchfield Customer Review (What's this?)

First off I Love Sirius programing! I also have XM but the programming is nowhere near the great programs on Sirius. The Stilletto is a very easy unit to install and program, the only thing that I was dis-appointed with is the self stick pad that is on the dash mount, it was not very good and will fall off, the last unit I got like this had extremely good adhesive and I had a heck of time removing it when I traded off the car. The unit comes with two batteries, and that was an unexpected bonus as well as two head phones, the sound quality is great and although this unit will mainly stay in the car it will most likely go portable when the summer gets here. It will be nice to have satelite radio on my segway.

Not ready for prime time

Crutchfield Customer Review (What's this?)

I returned this product after trying it out. The satellite radio reception is very poor even with the antenna headphones. The signal dropped out frequently, even in fairly open areas and walking down the sidewalk.

The antenna headphones are one of the oddest designs you'll ever see. A piece sticks into your ear which is quite uncomfortable after any length of time. The sound quality is not good. (I've heard the headphones for the Stiletto 2 are much, much better.) Unfortunately, the antenna headphones are essential since the satellite signal can't be reliably acquired without them.

The idea of a portable Sirius radio is very appealing. This unit just doesn't fit the bill.

Had the original Sportster for 3 years and was only able to listen in the car. I saw the price at Christmas on the SL100 and could not pass it up. Now not only can I listen in the car but now with the Wi-Fi I can listen in the house and get more out of my subscription. This is a great little unit and I am so glad I made the purchase.

Pretty Neat

Written By art1942us, Houston, Texas on Monday, January 07, 2008

I live in Houston, so this may have a bearing on the reception.

The Stiletto 100 is a very good product.

This may be atypical, but I can receive broadcasts in my home, even in the stairwell. I have good reception at my work place in a location that is not good for FM reception.

It works on a city bus and in my Wife's car. I could even listen in bed! I am very pleasantly surprised

The sound is very good, but the headphones can become uncomfortable, but I am guessing they are a necesary evil for good reception. I will try high end Shure headphones to see if they will work with the good reception.

Who need the Wi-Fi when I can listen indoors.

The Stiletto was a great gift from my Wife for Christmas.

I would like to see a good case for travel.

Sweet !!

Always said why would anyone pay for radio ! Well I love Satellite !!! The Stilleto makes it even better ! Easy install vehicle kit and home kit ! The WiFi feature is great for in home use ! No problems at all ! Just wish they would pump the signal into the NYC Tunnels ! Would prefer the Stilleto 2 for the ability to add more memory, but the price for this one couldn't be beat !

Crutchfield Customer Review (What's this?)

Being a Howard Stern fan, this purchase came naturally. However after reading all the negative reviews I put off buying for almost a year. I finally broke down with the intention of returning it, after trying it out. That was almost six months ago. I love it! Yes, reception can be spotty; its satellite, of course you won't get a signal under the trees. Yes, the antenna/headset isn't the most comfortable, but on a bike ride for 1-2 hours, I have no complaints. You need to buy a home kit to get the fm transmitter to work; combine it with a wi-fi connection, it provides a clean signal to every room in the house (home is 1500 sq. ft.) plus I ran an antenna to it, if theres a song I enjoy I press record; its there complete (granted the song started from the begining, using antenna reception). As stated it's not perfect, but I use more than I thought and absolutely do not regret buying it. Especially when doing yard work :) So if your an average guy who doesn't expect absolute perfection buy it you'll enjoy it.

Still not perfect, but awesome

Written By Michael, Pearland, TX on Tuesday, August 07, 2007

Sirius just released a new software upgrade for the S100 that allows premium radio recpetion via WiFi. This makes a HUGE difference in sound. Prior to this upgrade, I would only use WiFi for listening to talk and comedy channels because of the narrow bandwidth.

I don't use the satellite reception at home. I can bring the unit to work and get good reception from the ground antenna in Houston, but the battery only lasts 2 hours in this mode and gets uncomfortably hot. WiFi lasts a few more, but the library and radio replays give the best battery life.

It's down to this - This unit is not perfect, but I use mine everyday and love it. I hope the replacement that will eventually come out uses the same accesories, much like the Ipod series. At the new lower price, I would jump on this if you have a wireless home network and want to put a kit in your car. The unit gives you several options.

I bought mine at Christmas and have taken this with me every day. Enjoy yours!!

Not bad

Written By Jim, Alpena, Michigan on Wednesday, June 27, 2007

To address all the complaints from first time satellite users. You have to have a clear view of the sky to use this product (or any satellite product) they are after all satellites not radio antennas down the road from you. It will not work in a bus or a train with a metal roof, or in a car without an external antenna and car kit. It will not work in your home without a home kit and an external antenna or wi-fi and hi speed connection. It will work with the headset antenna with a view of the sky, it will work in New York while walking down the street if you can see the sky. It works fine on wi-fi if its an open access point, Not on one that is locked and you don't have permission to use.

Pros: Sleek design, Firmware update from sirius fixes many issues of battery and several things from other complaints.

Cons: Need more comfortable headset, better sound quality from wi-fi

True Ipod Killer - Buy It!

Written By jasonv, Phoenix, AZ on Thursday, May 10, 2007

Reasons for 'ipod killer' title:
- you can upload a couple gigs of your own MP3's
- you can SAVE ANY SONG FOREVER you hear played on any channel- then replay the song whenever you want (no need to buy new releases on itunes)
- it provides content- music, personalities, sports, news, weather, comedy
- i can drive accross the country on the same station no matter how rural the area

The recording option works great- it wakes up at 3am to record howard and i can fast forward the 5 minutes of commercials ever 75 minutes of show.

I love this thing despite some of the negative reviews below. The only negative is like most things the batteries don't last as long as they are quoted- but 5 hours is enough. I know a couple other people who own, and know how to use, a stiletto and haven't heard any complaints. It use to run a slow sometimes but I upgraded the firmware via the provided software and its fine now- that would probably solve some of the problems noted below.

I have no problem with reception- even in an office building at work WITHOUT an antenna connected i can get reception. FYI- the unit will not receive signal from the exterior car antenna if the dock is not plugged into power. I can hear it fine with 1 bar out of 3 with it sitting on my seat. The reception is also better if there are 'repeaters' in your area- I can get full signal in a parking garage in vegas. I can also get full signal outside jogging in phoenix. Don't forget the WI-FI (wireless internet) capabilities if you have signal problems.

SIRIUS Stiletto 100

Written By siriusly frustrated, Blaine Wa on Monday, May 07, 2007

I have been reading alot of reviews here and most I can realte to. I think I may have found a problem with the reception(outdoors). Why is it that when you have the unit powered by either the car 12volt power supply or the 12 volt power supply for the house the reception is excellent(with the car antenna). But if you leave the battery in and put it in the car dock, disconect the 12 volt power supply, you get aqiuring signal(with a fully charged battery) then do nothing more than simply slide the unit out of the car dock and it gives you a weak signal of one bar. Then simply slide the unit back into the car dock, unit on, and plug in the 12 volt power supply from the house into the car dock, VIOLA! three bars of signal! I think there is a huge problem with the batteries not being able to properly draw enough signal from the antenna,to get proper signal strength. As so many here have stated I am returning my unit to get a refund.

I really wanted this radio.

Written By tx1, West Covina, CA on Tuesday, February 13, 2007

Crutchfield Customer Review (What's this?)

Let me first say that I was not one who thought that I would get good reception on a Stiletto without some type of external antenna.

My first Stiletto and boombox was returned due to some unknown signal pronlem I'll never know.

My second Stiletto seemed to work fine (although as soon as you get your hands on it, the build quality feels cheap, like it won't last through much hadling).

It could use a scroll search when listening to the library (like an ipod),and there is no indicator of any kind that it's recording while it's in sleep mode (really needs one).

Then it froze up on me a couple of times, one time completely the other time certain controls. No big deal, just power it completely off then back on to fix it.

But the last straw was when it refused to play back more than 1 second of one of my sceduled recoredings, if it even recorded more than 1 second, who knows. I missed 3 hour chunks of two shows. I re-programed it but it still would not work properly. Everything went back. AGAIN!

I'd skip on the Stiletto if I were you. It's obviously got some bugs and you can tell the first time you use it.

And I REALLY wanted this radio.

What's the point?

Written By Matt, Long Island, NY on Thursday, January 18, 2007

Got Stiletto 100 after waiting for the post holiday price drop. Had the item for only 20 hours, cancelled my service and returned the product. This could possibly be the most dissapointing single purchase I have ever made in my life, here's why:

Pros: Sleek design, potential sound quality

Cons: Reception!!! I must of read atleast 100 reviews before the purchase, some good, some bad. Live on Long Island, only 20 miles from Manhattan and have a 37 minute train ride in. Can't get reception in my apt, on the street, or on the train. Oh and the ridiculous looking antenna headphones that make you look like a NASA technician, they don't work either. I bought the home kit, but don't need it, going back too. THIS IS NOT A PORTABLE DEVICE FOR NEW YORKERS! You're better off buying a Starmate or Sportster which comes with a car kit then buy a home kit. You pay less than half the amount then what you would for the capabilities of the Stiletto.

Don't waste your time, stick to the ipod or you can pay for the internet sirius which works well.

Important note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna. Sirius/XM includes extra wiring in order to address this issue, but Crutchfield strongly encourages customers to use an auxiliary input, wired FM modulator, or cassette adapter to ensure your satisfaction with the performance and cosmetics of this satellite radio.

SIRIUS Stiletto 100

Written By Seth, Long Island NY on Saturday, January 06, 2007

As an avid Stern fan and music lover, I was excited to receive my Stiletto for Xmas. My wife bought it when it came out in late October and I watched it in the box in her closet for 2 months eagerly awaiting to open it like a little kid. And on the big day I dashed to rip the box open, quickly activated it and NOTHING. The reception of this unit is terrible at best. The headphones feel like sticks in your ears. And I only got a signal 50% of the time when I was outside taking a jog..I think I had better luck with a first generation protable CD player. Then I got no signal inside either. So keeping cool I decided I would use it as a recorder off the Internet.guess what you can not record wifi. So no signal from the sky and no recording from the wifi.not much of a portable unit. In a last ditch effort I bought the home kit. (Thought I would then simply record from the SKY) the antennae only worked if I hung it out of the window and only worked 60-% -70% of the time.And then what is the point of a $350 portable with a $79 home kit..EVERYTHING WAS RETURNED. In my quest for portability I bought an internet recorder. Now I record Sirius and download to the IPOD..I can not believe anyone is happy with this unit.I live in Long Island not the sticks.if there is no service here then where?

Portable Live Satellite Radio??? STILLetto Not There!

Written By Mark, Middletown, NJ on Wednesday, January 03, 2007

First, this is not a reflection of Crutchfield. They are GREAT!
I commute to NYC from NJ by train and really missed Howard live in the morning. I live about an hour outside of the city-- in Middletown, NJ a suburb of New York and couldnt wait for Sirius to release their portable unit- the Stiletto. So I got it for Christmas- tried it around my home- it only worked in certain spots-- my expectations diminished. Then I tried it on the train this week. The only time I could get a sustainable signal was when I was about 5 miles outside of Manhattan. Then it was great. I was only able to listen for about ten minutes out of my hour ride. The signal really has to be enhanced for the rest of the metropolitan area.
The Headphones are what give the Stiletto its name-- you feel like there are two high heels jammed in your head. Poorly designed. The sound easily leaks out of them, too. Didnt anyone try wearing them for ten minutes? Maybe the technicians couldn't get their own signal either.
I have read other reviews by folks who say "its new technology" "give it a chance" or "its the same for all things new and will improve with time." And others who say its "Great!". Well, I disagree. First. it has to WORK and then you can make it better. The Stilletto does not at all do what it is supposed to yet. This was clearly rushed and released for the holidays. The price for everything is steep for the quality of the product and what it cant do. I wished I had purchased the slightly cheaper S50 unit that is portable but not live. I would have manged my own expectations better!

I had problems recording

Written By Jason, Hawthorne, NV on Tuesday, January 02, 2007

Well, I just got my stiletto for Christmas and I have to say that I love it. I have been with Sirius for 4 years now and it has only gotten better.

I would have to say, don't get rid of your ipod or any other mp3 player for this purchase, because frankly, it will not replace it as the memory is not even close, so I promise you, if you get rid of your 4 gb nano, you will not be able to put all of the songs on your stiletto.

The interface is absolutely great and very user friendly, my girlfriend was able to go through the whole thing and set everything up without any instructions as the functions are very similar to the ipod functions.

I have the car kit and that definitely helps for me, however, I am having problems recording the shows that I want. I've set it up 4 times to record Howard at 3 a.m. and it has not recorded one time, it says that it will wake up from sleep mode to record, but it has not.

As far as reception, with the car kit, I haven't had any problems at all. I haven't really tried it from inside the house yet, but I have been using the WiFi streams and it works perfect

One thing that bothers me is that if you plug in the antenna headphones, it blocks the power cord port, so if you do get a signal inside with the headphones, you are limited, because you can't supply the unit with the power needed.

I gave this 4 stars because it is 100 times better than the Kenwood Here2Anywhere receiver. I hope this review was helpful.

I'm gettin an ipod

Written By Tannia, Knoxville, TN on Monday, January 01, 2007

Crutchfield Customer Review (What's this?)

When I first learned about this product I was very excited. Being able to recieve live broadcasts in a compact package and the ability to record the songs or programs that I like was a dream come true.

In order to give Sirius a chance to work the bugs out I waited until Christmas to purchase it. Upon opening the package, I was very pleased with the user interface and the overall look of the product. And then I tried to access the satellite radio.

I had to stand in the middle of my street in 30 degree weather to get a single bar of reception just to create an account with Sirius. I gave the product a week to impress. Being a very active person I tried the radio in multiple places looking for some sort of signal. I am rarely at home (though it did not work there either), and it had no signal at work or at the gym. To top it off it only stores less than 1GB of personal music.

Overall it was a huge disappointment, and I am trading it in for an ipod.

SIRIUS Stiletto 100

Written By Lisa, Portland, ME on Sunday, December 31, 2006

Crutchfield Customer Review (What's this?)

I got this for Xmas and so far I am very pleased. The only complaint I have is that the satellite headphones hurt to wear and I hope someone comes out with a better version. The radio is awesome. WiFi works great and Sirius content rocks! I wish you could store songs when using WiFi, but no doubt, that is a copyright issue. The radio and Sirius content is excellent and if the headphones were better, this would get 5 stars.

Not quite a 5 yet

Written By John, San Diego, CA on Friday, December 22, 2006

This is our 4th Sirius in operation since Howard announced that he was coming. Had a whole year to find the stations I liked. All are active. My wife bought the S50 and sent it back after a week and finding out she couldn't record Howard's whole show. Software glitch they said.
This morning I went to the website, entered the new EIM, selected all the options and walked out front with the Headphone/Antenna on. It immediately updated the subscription. Then I selected Internet and it connected to our Wi-Fi. It's all good. She loves it...wearing it now.
It ain't perfect, but what is? It's close enough for now.

Very Versatile

Written By Randy, Montana on Friday, December 15, 2006

Crutchfield Customer Review (What's this?)

I'm very impressed with this unit. Yes, you do need a good signal source but this IS a satellite receiver. The internet connection works great. The sound is fine. The FM modulator is terrible. I even tried the Sirius adapter and it did not work very well. I did buy the Monster RadioPlay 300 modulater and it works great. The on/off/sleep/lock switch is of poor design. Almost everytime I try to unlock the unit I end up putting it in the sleep mode. This unit is so versatile it is like having three radios for the price of one subscription albeit you need docking stations or wifi wherever you use it.

Important note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna.

Stay with the S-50

Written By janisco, Washington, DC on Thursday, December 07, 2006

Crutchfield Customer Review (What's this?)

I was excited about the release of the Stiletto and pre-ordered it, only to return to my S-50. The Stiletto on paper is great, but in actuality isn’t. The problem? Signal. I ride the bus to work in DC; the signal would go in and out. If you drive in a car, you will lose signal every couple of minutes. It's simply too frustrating to own and use. As well, it’s too big to use to work out with, no remote, and you can Love button songs that auto save when you listen to your favorite stations. Stay with the S-50, now you can get the S-50 for an incredible deal including a home docking station. I tried to convince myself for a month that the problems were worth the cool new stiletto but finally became practical.

Not Perfect but Great First Attemt

Crutchfield Customer Review (What's this?)

Received my Stiletto last weekend and still discovering great new features. Love the idea of having Sirius access and being able to use the yahoo unlimited music service to go with the Stiletto. WiFi concept is great but does not pick up many public hot spots due to network protocol limitations. Outdoor reception without the headphones under clear skies is very poor at best. The unit is very user friendly and looks great. Sound quality is very good with wired connection. The FM transmitter is worthless with and without the car/home kid. Wired the car kid trough a Serious FM modulator and it sounds great. Home dock is wired directly to HK Amplifier using Bose speakers and sounds very good. I did not expect a perfect but I am overall very satisfied with the unit. Love Sirius, Howard, Bubba great music and DJ's. Just ordered my second Stiletto for my wife. Will buy more Stilettos once car kid is available. Great Product and programming. Love Sirius.

Suggestions for improvement:

Better outdoor reception
WiFi compatibility issue
FM Modulator performance improvement

I was soooo excited to get this unit. The idea of taking Sirius with me to the gym, through airports, etc. was a dream come true. And let me tell you it's way cool and a real head-turner - People continually ask about it when they see it. I think the only thing that could make it better is if it actually had decent reception. Plan on staring at a screen that says "acuiring signal" continually. It is so bad that you'll actually be surprised that you get signal. Maybe if you're a farmer riding a tractor out in a field you'll get great use out of it. But if you have anything more over your head than a sheet of paper, plan on not getting signal and being very disappointed.

Siriusly fed-up

Written By Daniel, Maryland on Tuesday, December 05, 2006

Crutchfield Customer Review (What's this?)

I started writing this review and it quickly began turning into a book of how not to run a business so, let me instead, condense and bullet the major points:

 I have purchased 4 items from Sirius in the last year. The S50, Stiletto 100, Exutive docking station for the S50, the home dock for the Stiletto 100. Out of those 4 things 3 where broken right out of the box.
 The products look good but function poorly
 They leave components and functions out that one would think to be an obvious need. SL-100: no belt clip or holder of any kind. Very poor design on receiver headset. Software: no way of finding out how much space you have on you unit. Exutive Docking Station: incredibly small holes for wall mounting.

My biggest piece of advice would be not to choose Sirius and if you do to purchase an extended warranty from Crutchfield because they know how to take care of their customers.

They got a bit ahead of themselves with this. You really CANNOT get reception inside any building. It is pretty much worthless unless you have the antenna headphones on when traveling outside of an area where they also broadcast over terrestrial as well as satellite. In order to get reception in my town you have to be outside under a pretty clear sky with the headphone antenna attached. If you try to run with just the earbuds, you get AQUIRING SIGNAL all the time and lose reception.

It is sufficient - but I think I would wait if I had to chance to do this purchase again - wait till they launched another satellite or something to increase the signal.

The wireless radio is nice - except you can't get NFL game or NPR over WiFi, which is the reason I bought this thing in the first that blows.

The music player is solid. The interface is pretty user friendly and the media wheel is very slick.

Best Sirius Ever!

Written By ivan, Springfield, MA on Saturday, November 11, 2006

This is by far the best Sirus radio ever! The sound is outstanding considering the low bandwith left for each channel. I have the Tivoli and Eclipse radios and they do not sound as clean as this unit does. I don't know how they did it but it sounds great! All the other features are fantastic but in the end is the sound is what counts for me.

A prepaid Sirius subscription introduced me to satellite radio when I purchased a new boat. My experience was poor, but I learned I needed a portable unit that was not limited to infrequent visits to the lake. When the Stiletto was introduced, I spent a $1,000 by purchasing the Stiletto, a home kit, a vehicle kit and a lifetime Sirius subscription. After 3 weeks, I am impressed. I am normally a late adopter on new technology, but the Stiletto has been a pleasant experience. I have two teenagers and am now able to relate a little better to the I-Pod generation. I have little interest in purchasing individual songs over the Internet, and was attracted to the ability to record specific songs, artists, and genres while listening to nonstop music. The Stiletto requires a home kit and external antenna at home. The Stiletto registers 3 bars with the external antenna. The FM modulator broadcasts a strong reception level to a stereo across the room, but does not reach other stereos in the house. Connecting through our home wireless router is not desirable since the music is interrupted during buffering from our DSL connection. I took the Stiletto to the office to see if WiFi was available and found that Satellite reception was available throughout the entire 3rd floor of a 10 story building. I am surprised that the reception (3 bars) is so strong but it prompted me to plug in some extra computer speakers and record songs I like, with a push of a button, during the day. I plan to test out the car kit this weekend and determine if I need the direct connection (included when purchased from Crutchfield) or can live with the FM modulator.

Best Portable Ever

Written By Mitchell, Westport, CT on Tuesday, November 07, 2006

Just switched over from XM. This new protable is the best I have ever used. The WiFi is a plus when you don't live close to any ground repeater. Get in line and get one of these little guys. you won't be dissappointed.

Only fair

Written By Sam C., Houston TX on Monday, November 06, 2006

I was really hoping for a portable from Sirius that would beat the pants off of competitors portables (including the mighty iPod). Sadly, this isn't it.

The receiver itself, while sleek, is marred by some rather odd placements of accessories: namely, the antenna headphones. They plug in at the bottom! They are terrible sounding and even more terrible in comfort. If you choose to use good headphones, prepare for a HUGE dissapointment in portable reception!

For $349, I expected, at the very least, a belt clip!! There is no car kit or home kit in the box ($70 extra - a piece). There is, however, two batteries, and trust me, you'll want to take both if you want to walk around with the Stiletto. The slim battery is lucky to net you 2 hours. The extended battery lasts barely 4 hours. Supposedly the Stilleto will hold 100 hours of Sirius content (on 2GB memory), but what use is 100 hours on a battery that lasts 4?

For indoor "reception" you get Wifi connectivity, but only 802.11b. This is better than nothing, but the fly in the ointment here is you only get the 32kb internet stream, which sounds worse than AM!! If you want the high-quality 128k stream, it costs an extra $3! Thankfully, you do receive Stern, but the NFL and news is off limits.

I can finally say some good stuff. The interface is terrific, and the screen is very clear and bright. The wheel is sleek and allows easy control.

Overall, the unit looks nice, but needs accessories and fixed features to even come close to being a great portable. I'd wait until the next generation.

Release was a DISASTER! Stiletto is just OK

Crutchfield Customer Review (What's this?)

I pre ordered this back in early September, and I've had it for almost a month now. I just received the car dock four days ago, it was supposed to ship with the stiletto, but SIRIUS (not Crutchfield, who has been great) couldn't get it together to get the cradles out in time.

Now that I can use the dock, I have tried to set up recording of a couple of talk programs and putting the unit in sleep mode. The manual says that when in sleep mode, the unit will power up and record the program. Funny thing is, this did work WITHOUT the cradle, but it won't work with the cradle.

Another problem is when I am trying to download MP3's onto the stiletto, it keeps "seeing" and then "not seeing" the stiletto. Kind of like I'm pushing and pulling the connector in and out repeatedly, but of course I'm not.

The unit does feel good in the hand, the display is great, the controls are deft and functional, the storage is adequate, the internet radio is ok - it needs more channels, the menus are great, and Sirius' content is superior.

Suggestion to Sirius:

Some different choices of antenna integrated head gear (hats, helmets, clip on antennas, etc), some belt clip and carrying case choices, an S-seek firmware upgrade option, and an in home satellite mini repeater will have people wearing this thing 24 hours a day.


Written By Motosiri, USA on Wednesday, October 25, 2006

I've had no problems whatsoever with my Stiletto. Reception, indoors or out, is quite satisfactory. Sound quality is good. The generous 100 hours of recording time in satellite mode equates to about 1500 four minute songs. You can schedule recordings in blocks of up to six hours, a noticeable improvement over the S50. The WiFi works well. I have no problems at all connecting with a network and receiving a reliable stream. The replay buffer allows you to pause, rewind and replay up to an hour of live content, an improvement over the 44 minutes in previous radios.

The Stiletto is NOT that big at all, even with the standard battery. I can easily hold it in one hand, while navigating quickly. The Media Dial is well thought out and simple to use. The color display screen is superb. It's about 32% larger and has significantly better resolution than the Inno display. The Stiletto is PlaysForSure compatible with several music services, supporting both pay-per-song downloads and subscription music. All things considered, this is a very nice unit. Definitely a worthy first live portable for Sirius. The vast majority of current and prospective Sirius subscribers should be happy with this unit. I give the Stiletto a big thumbs up.

Great product

Written By llx4, Wyomissing, PA on Saturday, October 21, 2006

Crutchfield Customer Review (What's this?)

I agree with many of the other buyers that a car kit should have been included. On the SL100, its great, easy to use and really has its advantages. I got around getting a home kit though....I just got an adapter to connect from the headphone jack and connected it to my audio jacks behind my receiver on my entertainment center...$5 vs $50+. Works great with the Wi-Fi!! I hope that there are going to be accesories for this as it is supposed to be portable and there are no arm bands/belt clips to use with the SL100. There have been a couple of times that were it has frozen up on me and the system was not able to reboot itself...I actually had to remove the battery.

Overall I am very happy with the SL100

Best Portable Radio I Ever Had

Written By robert, Saginaw Mi on Thursday, October 19, 2006

Crutchfield Customer Review (What's this?)

Iwas intimidated by it when I first opened it. But even 40 something me easily figued out how to work it. The WI FI option is so easy to use I couldn't believe it. And The reception using the satelite connection was excellent and worked well when I used it for my nightly walks. This is the coolest tech product I have ever owned.

Memory options are limited

Written By Lugosi, Northern Virginia on Wednesday, October 18, 2006

Although the Stiletto is billed as having 2 gig of memory, your ability to fully utilize that total is somewhat limited. For example, only 800 mb can be used for downloaded MP3/WMA files. The rest of the memory is restricted to material you record from actual Sirius broadcasts.

Individual songs that you may want to save can total no more than ten hours. Once you max out that ten hour limit, the Stiletto will automatically erase the oldest songs you have saved. There is no way to permanently "lock" those songs as there is with XM's Pioneer Inno. And as with the Inno, you are not likely to have a smooth break at the beginning or end of songs. That can be quite annoying.

Another 100 hours of memory is dedicated to material you record in blocks. For example, if you like Nina Blackwood's countdowns on the 80's channel, you can set the unit to come on automatically at 9 AM Saturday and record channel 8 for three hours.

The Stiletto does "fit" the new universal SUPV1 docking station. It will power up and receive a signal from your roof mounted satellite antenna. You can even change channels and save songs. The problem is, however, you can't actually LISTEN to it. the SUPV1 will not activate the FM modulator. And since the headphone jack is on the bottom of the Stiletto and thus blocked by the dock, you can't run a line out from the unit and listen some other way. Go figure.

SIRIUS Stiletto 100

Written By jared, San Francisco, CA on Wednesday, October 18, 2006

Crutchfield Customer Review (What's this?)

A pleasing ergonomic design, bright screen, and appealing list of features incorporated into the Sirius Stiletto portable satellite radio are wasted by a laundry list of functional problems. Unfortunately, the issues I experienced while using the unit outweighed promise held with truly portable satellite radio.

Reception is poor, even with terrestrial transponder signals at near-full strength. Simply moving the unit on the desk 20 degrees causes dropouts. Signal strength is most reliable when in clear areas with the (horrendously uncomfortable) earphone/sat receiver attachment in use.

You can not record from wifi streams. With poor satellite and terrestrial transponder reception the record feature does not meet my needs.

Firmware is unstable. I've had the unit hard-crash twice in the last hour while browsing the channel menus, requiring the battery to be removed to restart.

The unit runs extremely hot. The battery gives off enough heat that it is uncomfortable to carry in a pocket or in your hand for any extended length of time.

In the end, I couldn't do with the unit what I wanted in the first place -- record a four hour program to the unit from a live broadcast, then play it back on the train ride into work. The rest of the quirks, bugs, and flaws with the unit just added to the frustration. I'm sad to say that the Stiletto aims high and misses the mark by a long shot.

SIRIUS Stiletto 100

Written By mg, Danbury, CT on Wednesday, October 18, 2006

Crutchfield Customer Review (What's this?)

SIRIUS made a good attempt, but in my opinion they rushed to get the product out before Christmas.

Although I was skeptical about spending $13 a month for radio and $400 for the unit and a car adapter, I was willing to do it for the Stiletto. Why not, you could use the stiletto anywhere, take from car to work to the gym to your home and out for a run all while recording your favorite songs for free. NOT EXACTLY.

When I received my Stiletto in the mail, I was surprised how easy it was to operate. The unit was small enough to put in my pocket and the screen was clear and easy to read. I had signed up with Sirius within five minutes and began listening to live Sirius radio. Well I could not get live radio in my house, although I was able to use the wifi technology in my house. BUT, you can't record any of your favorite songs while using wifi technology. SO I walked outside and I could not hold a signal with the ear buds and if I used the headphones with the antenna (which are very uncomfortable), I would receive reception that was constantly going in and out. If I attempted to record a song while using the live satellite radio, the song would also go in and out just as the reception did. The reception in my area is good while using Sirius with an antenna hooked up in a car, but as for being portable it was horrible.

In the end I decided to return my stiletto and cancel my subscription with Sirius because all the stiletto is, is an expensive MP3 player or IPOD. I did not sign up to buy that. I am sure over time Sirius will improve their product, but until then I will keep my $400 plus dollars in my pocket.

Important note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna. Sirius/XM includes extra wiring in order to address this issue, but Crutchfield strongly encourages customers to use an auxiliary input, wired FM modulator, or cassette adapter to ensure your satisfaction with the performance and cosmetics of this satellite radio.

A decent receiver

Written By Satellitelover, Miami on Tuesday, October 17, 2006

Sirius finally releases a portable to match XM's INNO. As a subscriber to both services, I was thrilled to see a portable unit finally hit the shelves and picked one up last week.

First impressions: Sleek, sexy, nice color screen, "click" wheel and internal antenna. The unit itself feels solid (unlike the dreaded S50 before it).

Heres my pros/cons:

1) Live receiver on-the-go!
2) Excellent reception (when outdoors).
3) Wifi access when indoors (also see cons).
4) Lightweight
5) Two batteries (see cons).
6) Antenna headphones included.
7) Easy to use.
8) Excellent recording abilities (with some limitations...see cons).

1) Battery life. Yep, you'll hear this one again and again. You get 2 batteries, but combined they only have about 7 hours of life. This is not great at all.
2) No car or home kit in the box. I understand they wanted to keep the price down, but how in the world are you going to do any recording while on-the-go? Reception will be spotty for sure as your running around outdoors at times.
3) Wifi limitations. Yep, here's the kicker. You only receive the internet stream on the Wifi content. Which makes sense, but realize that you get no sports or news at all. You basically lose half the channels. Thankfully, you still get Stern if you're a fan of him.
4) Recording limitations. You have some limitations here (RIAA induced). Unlike XM's INNO, you can't save individual songs as files or folders. You can access each song by selecting the "next/previous track" key, sort of like a CD player.

Overall, a decent product here, and a much needed one.

SIRIUS Stiletto 100

Written By Richard, Mount Laurel NJ on Tuesday, October 17, 2006

Crutchfield Customer Review (What's this?)

I ordered my Stiletto to replace the S50, which doesn't work and has been on backorder from sirius for 6 months. I was excited to receive the Stiletto and once again have a satellite radio in my car. I received it last week! SURPRISE SURPRISE there is no car kit or home kit available yet. Crutchfield is taking orders but isn't sure when they will be in. Sirius says it doesn't know when they will be available and isn't even shown on it's site. However they told me that I can use the Stiletto as a portable radio with the head/antenna set it comes with! Well the head set has to be THE most uncomfortable headset I ever used. It actuall hurts to have them on my head and in my ears. When I do put them on and walk around outside or sit in a chair with nothing but open sky above me I have to move my head from side to side otherwise I lose the signal. I guess if I was a homeless person laying on the street in one position the radio would be great! However I live in a house and drive a car to and from work. The radio is useless at this time. I already have a MP3 player that is alot more portable then the stiletto. They should of not released the radio untill all the accessories are available!! I gave it one star because it looks nice!!!!!

Crutchfield Customer Review (What's this?)

I think this is going to be a great product. Very user friendly coming out of the box and setting up wi-fi. It would be nice if they offered all channels wi-fi, but then there would be no reason to buy a home kit. It is definitely better than XM!!

Programming disparity

Written By toivo, marquette, mi on Sunday, October 15, 2006

Crutchfield Customer Review (What's this?)

Holdoff until the programming disparity is addressed. I so was looking forward to being liberated from antenna problems. After activation I was shocked to discover that using the WiFi connection gave me access to a little over half of the standard satellite programming. I called the good folks at Crutchfield and they were not aware of the problems. After research they were just as surprised.

I would not say that the Sirius ads were out right lies, but they were certainly ambiguous. The obvious inference from the product discription was the channels available via satellite or wifi were the same. Regardless of how you accessed the content. I was VERY DISAPPOINTED that NPR, CBC, BBC, WRN and PRI could not be received via WiFi.

The lack of availability of docking units means you have to stick your head out the window to listen to NPR, any sporting events, weather, comedy etc.... I live in the Upper Peninsula fo Michigan and it is a real inconvenience to be outside in a full gale and blizzard trying to listen to the news on your brand new (and rather expensive new toy) radio. The integrated headphone/antenna is a very poor solution. The cable is very short and there are no other options for plugging in another antenna.

When satellite radio first came on the market I bought an XM and a Sirius. After a year of comparison I allowed my XM subscription to expire. My product loyalty was clearly with Sirius and I purchased two more units for our cars. I was willing to credit Sirius with real product innovations..maybe I

Good, but not great

Written By SatRadFan, Memphis TN. on Tuesday, October 10, 2006

This a good first attempt at a "live" portable by Sirius. Reception wise, it works like any other satellite device, meaning line-of-site to a satellite or a repeater.

The interface is easy and uncluttered, a plus in my book. The screen is easy to read and looks nice as well. The Wifi, while a neat concept, will only really be useful indoors at a house or certain hotspots. My business doesn't allow non-business devices WiFi access, which I'm sure most businesses do, so at-work use will be limited.

Recording is very easy and practically unlimited. Thankfully they learned a lesson from the S50.

The unit is lightweight and comes with every accessory conceivable for portable use. Well done.

My two biggest complaints, thus giving the overall score a "3" is, no car or home kit included. At $349, I expected at least one of them.

The 2nd, and biggest, complaint is battery life. I'm sorry, but if you think 4 hours is good you have really LOW standards. Pre-recorded life at 10 hours is decent.

Overall a good, but not outstanding, product. Well done.

Simply AWESOME!!

Written By sofiav, NY, NY on Monday, October 09, 2006

The Stiletto is great if you want on-the-go "LIVE" NFL, Howard Stern, The Playboy channel, NASCAR, or even better, the 64 channels of commercial-free music of all styles and genre.

The WiFi feature works great right out of the box. If you have an 801.11g router, just make sure you set it to b/g mixed-mode(Stiletto uses 801.11b), and broadcast your SSID, so the Stiletto can connect to it. It can also connect to secured WiFi as long as its WEP or WPA password protected and you know the password.

Its filled with great features too. It remembers where you last stopped in the pre-recorded streams. It allows you to skip forward to the next song. You can tag a song you like, save it to your library, and/or later automatically buy it online. You can automatically set it to record up to 6 hours of any channel. It automatically records your favorite channels for future listening(like TIVO). The graphical interface is very intuitive, easy to use and responds quickly, for fast navigation. The beautiful color TFT screen is large and crystal clear. At any point in time, you can listen to the Stiletto from 4 different options: LIVE Satellite radio, LIVE Sirius internet radio, your library of saved songs, talk shows, MP3s/WMAs, and radio replays automatically saved from your favorite channels. Too many features to list all.

I havent watched TV since I got this. I listen 8-9 hours a day. The content is THAT good that I cant put it down. Theres so much commercial-free music and incredible talk shows that you can listen all day and night without ever getting bored. Sirius satellite radio is addictive.

Overall a great product. Very versatile. Sold my Ipod!!

Hello ,
I am a new stiletto owner(2 days ) and I am overall impressed with the unit,it works well and is well thought out.I especially like that it comes with the antenna headphones which are a definite must where I live in the mountains of the poconos in northeast pa. and I also like that it comes with an extended and a regular slim battery.I find the WIFI part a bit frustrating becuase it is only compatable with 802 11B and not The "G" Band which is what I am using.

Sirius Roxxs!

Written By Plightman, Winston Salem, NC on Thursday, October 05, 2006

It's about time. Thank you sirius for providing an incredible product. The cost is kinda steep but you get what you pay for. The complaints above are typical for people who think everything is suppose to work like a mythical device that has zero flaws. Like anyone could expect zero drop outs. Common sense typical prevails over these issues. A carrying case is needed and will probably be offered seperately.

Excellent given what it is - new technology

Written By Rensalier, Atlanta on Thursday, October 05, 2006

Read the other reviews and I agree with many of the statements regarding how the radio operates and some of the fixes that need to be put into place. I have always been an early adopter of technology though and given that this radio is just that, I believe it is an excellent effort.

I can remember my first iPod and I would say it was about at this quality level when I first got it. Look at where they are today. This effort needs to be given time as well. Some will say the price demands the fixes now but this type of technology is iterative. Those that buy now are paying to have the technology.

If you are looking for greater sophistication with all the fixes in place wait for a while. The price will drop and the fixes will come. If you agadget freak like me - enjoy.

SIRIUS Stiletto 100

Crutchfield Customer Review (What's this?)

Received the Stiletto this afternoon as a much anticipated wait. The unit is much smaller than the XM portables and works much better....with or without the headset antenna. I am disappointed with the fact it does not come with a remote control and it appears the car kit (back-ordered) or the home kit will come with a remote either. The internet streaming works great..another reason I'm disappointed no remote appears to be available. Finally, a real handheld from Sirius. See you later XM Radio!!!!

Most Advanced Radio

Written By Steven, Elkridge, MD on Tuesday, October 03, 2006

Crutchfield Customer Review (What's this?)

First off, I have to say this was worth every penny. This package includes the antenna headphones and regular headphones, but I used some other regular headphones and they sound SO much better than what I was lagging around with a battery pack and a Starmate ST2.

I have to say first and foremost that the Satellite Radio part is not real impressive, this coming from someone who supports Sirius every step. The reason it's not impressive is because even though I've getting intermittent signal in the living room, I'm getting a signal upstairs. However, one bar outside for Satellite Radio and inside? I don't think so.

However, the Internet Radio just blows the Satellite part away. I'm getting so much CD-quality from these regular headphones. This is especially great for free WiFi hotspots!

I managed to store Dani California in the Stiletto with just one click. This is why I sold my Starmate and iPod. This is a combination between an iPod and Starmate Replay with the same characteristics of the S50.

In the design, the scroll wheel was awesome. Felt rubbery to the touch and smooth on the outside. Eight buttons on the front and a lock button on the side make it an ultimate player.

Excellent, yet Unrefined...

Written By RANDY, New York on Sunday, October 01, 2006

I already own the XM Inno, so I used the Inno to compare it against the Stiletto.
Overall the Stiletto is VERY good. The screen looks amazing..and is very easy to read. After a little time with the unit you may love the's very responsive and overall well laid out. The Stiletto sounds VERY good. Surprisingly the antenna headphones it comes with are rather good too, but a bit uncomfortable. I found at least where I live, you almost HAVE to use the antenna headphones or you will get a ton of dropouts. It's the same with my Pioneer Inno. I guess this is a Satellite's not the player. As far as sound..maybe it's just Sirius, but the Stiletto sounds WAY better than the Inno. Much less compressed sounding.., plays VERY loud and very clear. My biggest negative on the unit is it has NO tone control, NO eq. I think this is an insult on a player costing near $400. That being don't NEED bass or treble..but it ought to give you that option. Other than lack of EQ, there's not much else to complain about here. My overall impression is WOW..this thing is great, but also..that the Stiletto and it's software are a bit unrefined overall compared to the Inno. The Inno feels more sturdy..and the Stiletto more delicate,but it still feels like a quality product. One of my favorite things on the Stiletto is a voice will sound on each channel TELLING you the name of the channel. This is GREAT, and quite useful if say you are exercising,and can't look at the screen. Overall I think Sirius subscribers will be rather happy with the Stiletto. Mine froze once..but I simply removed and put back the battery and all was well. OVEALL it's great!
