Our take on the Sennheiser PXC 450

by Ralph Graves
Sennheiser

Get relief from the din of travel with Sennheiser's PXC 450 noise compensation headphones. These around-the-ear headphones use active noise cancellation technology to reduce external sounds, such as airplane engine roar, so you can listen to your music at lower and safer volume levels. Tiny microphones built into the earcups pick up the sounds of your environment. Advanced circuitry then creates a signal that "cancels out" much of this external noise without affecting the sound of your music or movie soundtrack. A convenient "TalkThrough" button lets you carry on a conversation — such as responding to a flight attendant — without removing your headphones.

Generously padded earcups and headband lets you wear the headphones comfortably hours on end — great for extended trips. The PXC 450s fold together for compact storage and fit into the provided soft belt pouch for convenient travel.

From the review Sennheiser PXC 450 headphones: Quiet and comfortable — even at work

"It wasn't until I put [the PXC 450s] on that I became aware of just how much office noise I had gotten used to. They also performed well as headphones, delivering my music with a full, detailed sound. And the PXC 450s were so comfortable I sometimes forgot I was wearing headphones — until I realized I could barely hear my coworker. Thank heavens for that talk button!"

— Ralph, Crutchfield Blog and Product Review Editor

Features

Overview: The Sennheiser PXC 450 are closed, dynamic, over-the-ear stereo headphones with the latest active noise compensation technology know as NoiseGard 2.0, designed for use with any entertainment system, including in-flight audio systems. Passive and active noise reduction enables you to enjoy music even in noisy environments.

NoiseGard 2.0 Noise-cancellation Technology: NoiseGard technology is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard actively compensates the noise, based on the physics principle of sound and counter-sound. NoiseGard 2.0 has perfected the NoiseGard principle thanks to the use of optimized circuitry design and even more efficient processors. It also uses better quality microphones, which enable more sophisticated pick-up of unwanted noise. Specially developed filter algorithms enable improved active noise compensation of up to 90% (23 dB) for frequencies below 1 kHz. It is of course also possible to use these headphones passively, without NoiseGard and without batteries.

TalkThrough Function: When using the PXC 450 headphones, you can communicate with your friends and family without taking off the headphones via the TalkThrough function. When the TalkThrough function is activated, professional quality microphones mounted on the outside of the headphones pick up all acoustic signals in the immediate vicinity. Unwanted background noise, such as the sound of the engines on a plane, is filtered out electronically to a great extent, so that only the person's voice is passed on through the headphones into the your ears in top audio quality.

Diaphragms: The patented Duofol diaphragms prevent unwanted partial oscillation to provide a highly natural, lifelike sound quality.

Volume Control: The headphones volume can be adjusted directly on the headphones from the right earcup's volume controls.

Comfortable Fit: The PXC 450 provides a comfortable fit and high level of passive ambient noise attenuation thanks to its over-the-earcup design and padded headband made of top quality materials.

Removable Headphone Cable: The headphone cable of the PXC 450 can easily be removed and replaced for long service life. You can also remove the headphone cable to use the headphones as a passive hearing protector device.

Airline Stereo Audio Adapter: The supplied airline stereo audio adapter allows connection to a variety of aircraft entertainment systems.

Travel Case: The headphones fold together for compact storage in the provided case, making them an ideal travel accessory.

Best headphones for studying

Written By Jim, Austin, TX on Wednesday, July 02, 2014
Crutchfield Customer Review (What's this?)
 
I have the opportunity to study at work so I needed some noise-cancelling headphones to block out the ambient noise of my coworkers. I work in a conex (container) that is about 7 feet wide and 40 feet long with military grade environmental control units blasting constantly and 2-6 people in the same room as me having conversations and speaking loudly. The majority of the noise from the ECU's is eliminated with the noise-cancellation...as for the conversations...well, let's say the voices are diminished but not removed outright. It seems that the more background noise there is or the louder it is, the headphones don't do quite as much. However, for humming equipment or other irritating sounds at lower decibels, this product works great.
Pros:
Well built, look great, mostly effective with average office noise and even above average noise, comfortable
Cons:
Not wireless, no bluetooth, larger size, does not eliminate all noise, turning your head away/toward a sound source may lead to nausea or dizzyness.

Great investment

Written By Jody, Alexandria, MN on Sunday, June 15, 2014
Crutchfield Customer Review (What's this?)
 
Just an all around outstanding product and definitely worth the investment if you are a serious music listener. I purchased these to replace a broken pair of another brand headphones that I use on my digital keyboard. I've had the keyboard for many years but hooking it up to these headphones was like getting a whole new keyboard. The sound reproduction is outstanding, providing a clear warm sound. Comfort is excellent (I will wear them for several hours at a time and not notice they are even on). They are built sturdy and come with a nice case. The cord if detachable, and therefore replaceable if it should wear out, though I doubt that will happen any time soon. They are very good looking headphones, but I have seen some headphones out there that I was say are a bit cooler, thus the 4 stars. But isn't that a personal preference anyways?
Pros:
Sound, comfort, quality of materials/build quality, detachable cord, noise reduction options, case, looks

Very pleased

Written By Liberty, Utah on Monday, May 05, 2014
 
Keep in mind I am hearing impaired. These headphones are amazing. The comfort of the ear cushions is unbelievable, I can finally listen for long periods without any discomfort. As for the sound, it's incredible and clear. Noise canceling is superb ( but I am hearing impaired so it is possible I wouldn't hear some outside sounds as it is) Coolness factor? I think they're really cool looking. Then again, I'm 44 so my kind of cool could be outdated. lol
Pros:
Excellent sound quality, durability, and noise cancellation. Comfort.
Cons:
I always forget to turn them off when done so I finally got smart and started using rechargeables

Sennheiser PXC 450

Written By Mike M, Henderson, NV on Wednesday, November 06, 2013
Crutchfield Customer Review (What's this?)
 
My previous headset was a Bose QC 2 and wanted to try a full ear cover noise canceling headset.

The Sennheiser PXC 450 received enough good reviews for me to give them a try. Upon receiving them, the first thing that I noticed was a persistent low frequency rumble. And over time it has become more persistent, especially on airplane flights when it seems that it magnifies the low frequency noises (especially landing gear noises, flap extension/retraction). An semi-educated observation is that the noise cancellation is out of phase.

Even more annoying is the response from Sennheiser customer support; "it is normal, live with it".

As soon as I return from Saudi Arabia, they are being returned!!
Pros:
Volume controls, pause control, sound quality.
Cons:
Persistent low frequency rumble. P... poor customer service from Sennheiser.

Exceptionally clear

Written By MHB, Rockville, MD on Wednesday, August 21, 2013
Crutchfield Customer Review (What's this?)
 
Let's face. They aren't cool. My coworker says that they make me look like a space alien. At least, I assume she means the headphones. But they are amazing phones. I have tried top of the line Bose and Sony. This one beats them. First of all, the passive pass-through. Battery down? No problem, you still get sound. And what lovely, clear, natural sound. I have found I don't even need the NR on at all, ever (well, on the subway or train). The sound isolation is that good. And the comfort. So when the earpads wear, just buy a replacement pad set-- OEM please-- they are so comfy. Not to mention the build quality. 4 years riding on the subway, M-F, till finally one of the earpiece plastic pieces broke. It's probably fixable, but I just bought a new pair anyway. BTW, the Bose didn't even last a year with that kind of daily abuse.
Pros:
Hands down best isolation ,best versatility, best sound.
Cons:
Bulky. Sorry, you are not cool wearing these things.

Awesome, if you like batteries

Written By Jason H, New York, NY on Thursday, May 23, 2013
Crutchfield Customer Review (What's this?)
 
One of the only things I own that still uses crappy, environmentally unfriendly disposable batteries (more on that later). Big, bulky and maxes out at a fairly low volume if you like your music loud (thank you nanny state). Worst of all, if you leave them in a drawer for a few months with the batteries in, be prepared to kiss them (and the money you spent) goodbye. That's what happened to me, but I guess not such a big loss. Save yourself the trouble and buy Klipsch.
Pros:
Sound quality very good.
Cons:
Bulky. Sound quality zero when the craptastic old school battery feature goes awry.

Haven't Given up Yet

Written By Outdoors Guy, Iowa on Wednesday, April 24, 2013
Crutchfield Customer Review (What's this?)
 
I have a couple issues with these but I haven't given up yet. They are large and bulky and I don't look forward to taking them on a plane. They were also quite expensive. The noise reduction doesn't drown out my neighbor and the rock tumbler he uses for a lawn mower. I've also noticed a bit of ear discomfort after wearing for a long period of time. That being said, the sound and dimension of sound field provided is excellent, whether it be listening to tunes on the computer or playing a game on the iPhone. Bose are very cheap feeling compared to these.
Pros:
Great sound, quality build.
Cons:
Bulky and pricey.

Not that great.

Written By DP, San Diego, CA on Saturday, November 24, 2012
Crutchfield Customer Review (What's this?)
 
These headphones sound good, but not as good as I expected. I bought them for their noise-cancelling feature, which I found disappointing. On an airplane, they don't really cancel that much of the background noise. In fact, when turn off the noise cancelling, it's just barely different. I think it's because they don't fully enclose your ears, so a lot of sound leaks through. Also, on an iPod or a laptop, you have to turn the volume to maximum just get a reasonable listening volume. If you want it louder - you're out of luck. Also, I don't understand why they don't include a microphone in the cord, so you could answer a phone call. So, overall, not bad, but for the price - disappointing.
Pros:
Nice storage case. Clean, clear sound.
Cons:
Volume is lacking. Noise-cancellation is sub-optimal. Not worth the price.

Sennheiser PXC 450

Written By Scott, Ohio on Saturday, September 08, 2012
Crutchfield Customer Review (What's this?)
 
I bought these after a long struggle to choose between the Sennheisers and the Bose Quiet Comforts. I chose these based on reviews of comfort and overall sound. Unfortunately and suprisingly the ear cups are TOO large. I have admittedly large ears and my ears touched the housing, not the rim, but the inside frame which was very surprising and uncomfortable. I've not encountered any other headphones that have large enough cups to have this issue. The sound of the headphones was very good. However, with just the noise cancellation turned on with no sound, turning my head side to side produced a very awkward low frequency "rumble" that was somewhat disorienting. I've read about this in other reviews, but it was not often mentioned, so I decided to try them out. This issue alone was enough for me to return the heaphones and get the Bose Quiet Comforts.
Pros:
Solid build quality Nice sound
Cons:
Horrible low frequency "rumble" on noise cancellation Ear cups too large

Sennheiser PXC 450

Written By Brendan, NH on Saturday, April 07, 2012
Crutchfield Customer Review (What's this?)
 
I had a horrible experience with these headphones. I listened to them for 10 minutes and was disgusted by how much these cost in comparison with how they sound. My brother has a pair of beats by dre solos, the bottom of the line of over ear headphones for beats by dre, was better and not to mention 150 dollars less. These headphones had no range and I had to turn my ipod all the way up to hear any quality. When I did have it all the way up it was still not loud enough, in fact it sounded like the volume was half way up on the headphones I had previously had. These headphones started to sound like they were going to blow. These headphones are also extremely unappealing to look at.
Pros:
Only good if you listen at extremely low volumes
Cons:
Very large, unappealing to the eye, no bass, have to turn ipod all the way up to hear anything, barely any noise isolation.

As other users have stated, the headphones live up to their price and reviews. Excellent sound, easy to use controls and noise reduction is outstanding, even when you're seated over the engine of a 737. They pick up the most minute sounds in any genre. Also, Crutchfield's customer support is outstanding- quick delivery and follow up to make sure I was satisfied with the product.

Great for travel and home

Written By ScottM, Atlanta, GA on Saturday, January 28, 2012
Crutchfield Customer Review (What's this?)
 
After more than 50 hours of time in airplanes and almost as much usage at home and at work in the past month, I have to say these are excellent headphones. Most of my flight usage is on those 13+ hour legs to and from Asia. Even though these are sealed around the ears, there's no overheating or fatigue or need to take them off after a couple of hours. The talk-through feature is a must-have. It's already hard to imagine not having that feature.

Based on a lot of review reading, I also purchased a PA2V2 amplifier to give my mobile devices a little more juice. I find myself using mostly on the really long flights but amplification probably isn't necessary when you get used to hearing all the music verus hearing some of the music loudly.

Although I bought exclusively for flights, I've used just as much at home with the noise-cancelation bypassed. I listen to a lot of Pandora and it sounds great even though I'm not listening to lossless content.

While my sound references are mid-range earbud headphone, these are exceptional-sounding. While I wish there were more volume headroom, I find myself not needing to crank it up because I can hear all the details and none of the outside noise.

So far I only have 2 complaints: 1) When noise cancelation is activated and I'm listening to an iPhone or iPad, I sometimes wish there was a little more volume capability. 2) They're so nice, my wife steals them.
Pros:
-Sound isolation -Comfortable enough to wear for long periods -Sound quality -Compact carrying case (given they're substantial around-ear headphones)
Cons:
-Volume from mobile devices -Exposes how poor many recordings really are

Best on the Market

Written By jonas1jp, Columbus, IN on Tuesday, December 27, 2011
 
I tested many other headphones prior to making the move to purchase these. B&W, Bose, Beats, none of these compare to the PXC 450. These headphones are the best by far for the money. No comparison. I am an audiophile level listener, so I am very particular about the sound of my music. These will satisfy even the most critical music enthusiast. I am a Sennheiser fan for life!!
Pros:
Mids, Highs, Clean Lows

Sennheiser PXC 450

Written By JimA., Rochester, NY on Monday, June 13, 2011
Crutchfield Customer Review (What's this?)
 
I was very concerned about purchasing this set vs. a Bose. I've wanted a Bose for years, but the mechanical quality issues worried me. I'm very happy with this purchase. I just finished an 14,000 mile international flight and shared them with many people. The reviews were all good, even from Bose owners. The talk through button is excellent and the construction appears to be better than Bose. Being functional if the battery dies is also a very useful. The case is about half the size of my laptop but manageable because it's so thin. Although I perceive that the Bose is quieter, I've decided this is more than adequate for what I need and the best trade-off. It doesn't have to be dead quiet, it just has to be conversational level or less, and they certainly do that.

Very comfortable

Written By CharlieG, Hamilton, NY on Monday, May 02, 2011
Crutchfield Customer Review (What's this?)
 
I have a large head! The Bose QC just barely fit, the Dr Dre Beats were very uncomfortable but these! I don't even have to move the phones out as far as they can go. That is a first for me. I can listen for hours and barely know that I have them on.
Sound is great - except I look for more bass than I probably can get from headphones. These are as good, bass-wise, as the other 2 and the rest of the music output is as good or better.
In my opinion, the Bose has the best noise canceling of the 3 if that is important to you.
I am glad I tried all three and I am very pleased with my purchase of the PXC 450s

Nice Sound Quality, Not As Comfortable As QC15

Written By Song, Ann Arbor, MI on Thursday, March 31, 2011
 
I have been using this PXC450 for more than 2-years, which replaced my Bose QC15. As other reviews mentioned, the sound quality of the PXC450 is clearly better than the Bose QC15. You can itentify more sounds in the sound track which you can't hear with the Bose (too heavy on bass). But I found this PXC450 is not as comfortable as the Bose to wear. One thing is: it is a little too tight than the Bose which puts too much pressure to the side of your head, secondly it is not as easy to find a perfect position to wear without your ears touching the inner structures in the headphone. The last thing I think Sennheiser should improve is the carry case. It gives you a cheap feeling. It doesn't match the price you pay for this expensive headphone.

Sennheiser PXC 450

Written By JanineE, Philadelphia, PA on Tuesday, February 08, 2011
Crutchfield Customer Review (What's this?)
 
I've had these headphones for about a month and am (so far) quite impressed. Using them mostly in an office setting with a computer, though I've tried them at home with a Marantz rig to very nice results. Range on these is wonderful- I'm hearing things I've never heard before in (familiar) music. Compared them side by side with the new Monster Beats Pro... while the lower notes really shine through with the Beats, the Sennheisers are crisp and clear and really bring out what I want to hear when I listen to music. They're both fantastic headphones and well-made, but just focused on different strengths. I haven't yet traveled with the 450s, so not sure how that will go. They're a bit bulky, so not sure how that will work when I try to sleep during a red-eye. Otherwise, the Sennheiser PXC450 has thufar given me a completely comfortable, solidly built, and a fantastic listening experience.

Get 3 AAA rechargeable batteries and charger

Written By Florida, Florida on Monday, January 17, 2011
Crutchfield Customer Review (What's this?)
 
This has only been used in a house on a computer. The comfort level is wonderful.

The sound isolation without the noise cancelling is very good. The noise cancelling is excellent.

It uses one AAA battery that lasts ten hours. A rechargeable battery lasts about 15 hours. You can buy a charger for about 15 dollars but it usually only comes with AA batteries although it will charge AAA batteries. But usually these chargers only work when there are two AAA batteries in the charger. Consequently, you need to buy three AAA rechargeable batteries to always be able to use the noise cancellation feature.

Excellent Travel Companion

Written By Jaime G, Santa Fe, NM on Wednesday, January 05, 2011
Crutchfield Customer Review (What's this?)
 
I would have given these a 5 star rating, but I still feel that I get a better sound response out of my Sennheiser HD280's (which are significantly cheaper but don't have NR technology). The componentry that provides noise reduction seems to attenuate the signal response (manifested as a reduction in volume and clarity). This can be a problem when playing sources with limited power (like cell phones). I get great sound out of my ipod, computers, and home receiver. These headphones appear to be well constructed, travel well and do EXTREMELY well with airplane and road drone and are comfortable all day. The earcups are large and do require a snug fit for the NR to work properly - this becomes a problem at times when you turn or tilt your head as the movement will sometimes break the seal and create un uncomfortable humm from the speakers. These are definitely comparable to Bose as far as NR and I'd say better in the sound quality department.

Excellent

Written By Siggy, Shenandoah Valley, VA on Friday, December 24, 2010
 
A great sounding pair of full coverage headphones. These make the outside world disappear when listening to them. The pass through feature allows them to be used without a battery if you find yourself with a dead one or without a replacement handy. Folding them properly takes some practice and instruction reading, but it is a very well thought out design, and they are fairly compact when in the included case. These are very comfortable and can be listened to for hours without discomfort. Highly recommended.

Sennheiser PXC 450

Written By JeffS, Old Bridge, NJ on Sunday, November 28, 2010
 
The best performing noise-cancelling headphones I've used. I find these much more accurate than the Bose products, which seem to over-boost the bass. I also like the fact that these can still function as headphones (without noise suppression) when the battery power is shut off or run down.

bose vs sennheiser

Written By customer, ny ny on Wednesday, January 28, 2009
Crutchfield Customer Review (What's this?)
 
Used the best Bose had to offer w noise cancellation for 2 yrs & used the best Sennheiser had for two months. Bose has very good sound but the materials used are very cheap plastic & is designed to fall apart after 2yr of use. Sennheiser has superior sound when you set to the right Ipod EQ setting. On quality of materials, Sennheiser is a Cadillac.

Better noise reduction than Bose QuietComfort 2

Written By Jakob, Fremont, CA on Wednesday, December 03, 2008
Crutchfield Customer Review (What's this?)
 
I used to travel with the Bose QuietComfort 2, which indeed does provide good noise reduction on airplanes. However, I now prefer the Sennheiser PXC 450, which is even better.

The difference between the two headsets can be summed up by this one observation: I can listen to classical music on airplanes with the Sennheiser, which I could not do with the Bose. The quiet passages were drowned out by the remaining airplane noise. No noise reduction is perfect, but Sennheiser provides just enough extra that classical music now works for me.

I can't tell much difference when listening to rock music, though. Also, the Bose was fine for classical music when listening in a hotel room at the end of the trip, but that's not why I bought a noise-cancelling headset.

Other reviewers have complained about the buttons on Sennheiser, but I find them fine. The fit over the ear is more finnicky than Bose's fit. If you don't position the Sennheiser headset just right, some protuding elements do touch parts of my ears. This is a bit of an annoyance: with Bose, I just put the headset on and it worked, but with Sennheiser I have to fiddle. But the better sound is worth it, in my opinion.

Sound privacy - at last

Written By cam, Price, UT on Monday, October 20, 2008
Crutchfield Customer Review (What's this?)
 
The Sennheiser PXC 450 headphones arrived safely and well packaged - also very promptly.
I found it a little odd that the english language portion of the manual was buried in the middle of a rather thick folded booklet. It made me wonder where the bulk of the world audiophiles live - Germany or France - I am sure.
The only problem I had with the product is that the on/off switch is finnicky - it has to be pressed and held in just the right way to toggle - but it has gotten easier. I seriously considered returning them to Crutchfield -but so far continue to turn on/off with a little persistence.
The sound from these headphones is wonderful - lacking a little in the low frequencies but they perform as advertised

Thank you Crutchfield!

Keeping it simple.

Written By Julio, Somewhere in New Jersey on Saturday, October 11, 2008
Crutchfield Customer Review (What's this?)
 
There are already many reviews describing this product in detail. So let me give you a simpler one that will hopefully make it easier for you to decide.

They weren't kidding about the Noise Canceling feature. I now have an excuse as to ignore my wife's requests or my son's constant banging/tapping on that annoying guitar hero :) I pray they never read this review.

The sound is truly amazing, whether I plug it into my computer, amplifier, or iPod, the sound quality remains the same.

I have a few Bose products, so I am a Bose fan. I need to hear every instrument that is recorded on a CD. So I have two Bose speaker systems(Acoustimass III & XVI)that provide that sound for me. Unfortunately, when it came to their headphone line, I wasn't really impressed. The Senn 450 does what Bose does for me when I'm not listening with headphones.

Don't buy these on an impulse, do your homework so you can truly appreciate them when they finally reach your door step.

Good luck.

Frequent Flyer Executive - Travel Improvement

Written By Charles, Atlanta, GA on Saturday, September 20, 2008
Crutchfield Customer Review (What's this?)
 
In short, this product is excellent. Other products purchased and compared to this one included the Bose, Sony and others. The quality of construction, comfort, sound, features, portability, all superior. While the headphones may be the largest in their class, they are actually of a lower profile than most other seamingly smaller headphones. The equates to a travel friendlier dimension combination for a backpack or briefcase. The headphone can be used in a home w/out the noise canceling, in which case they are much better sounding than the other competitors. Or, they can be used in an airplane w/ noise canceling, in which case they really standout. The range of frequencies that are cancelled are really geared towards a low thundering noise that occurs on the airplane. By the way, on my trip to Europe last week, I saw them for sale at a retailer for $648 (US dollars, after currency exchange). So glad Sennheiser built these. I was getting tired of mass marketted junk. The PXC-450's will deliver as demonstrated on the Sennheiser advertisement, on their homepage.
Enjoy!!

Well Worth the Money

Written By Chuck, California on Sunday, September 14, 2008
Crutchfield Customer Review (What's this?)
 
22 hours of flight and fatigue was not an issue. These are very comfortable when wearing for long periods, in fact, 11 hours at a time. Sound quality is fantastic and noise reduction is the best I have ever heard. It works well with BlackBerry phone and airplane sound systems. The talk through feature is awesome.

I own two of these and don't regret spending the high price for either of them.

First class product with a couple of caveats

Written By Bruce, NYC, NY on Wednesday, February 20, 2008
 
As you would expect, the PXC 450 is an excellently crafted and high performing product. The noise cancellation is as good as anything I've experienced, including Bose. The Talk Through button is a nice feature that lets you toggle noise cancellation in the event that you want to be able to hear what is going on around you in addition to the music you are listening to. By my ears, there are two items the propsective buyer should know. First, while the PXC 450 gives exceptionally clear sound, it is weighted more to the treble than the bass, as compared with, for example, the Bose series headphones. Second, the earphones fit very snugly. It is possible that someone could find the pressure uncomfortable when listening for long periods of time.

noise-cancellation headphones set new performance standard

Written By Mark, Oregon on Friday, September 21, 2007
Crutchfield Customer Review (What's this?)
 
The best noise-cancellation headphones: both in terms of ability to block outside noise, and overall sound quality.

Build quality is excellent. I'll be taking these on the bus; they need to be able to survive a bit of rough handling.

Sennheiser stands behind their products, and makes them easy to repair. Earcups and cables are easily replaced.

You will experience a quiet environment, even in difficult conditions such as a crowded bus. These are capable of blocking most types of noise (most others are functional only for reducing consistent rumbling or hissing types of sounds).

The talk-through feature works well, but can lead to confusion. Even if I'm carrying on a conversation and answering questions, the other person may be skeptical: "You can REALLY hear me?"

The 150 ohm impendance is an issue. My MP3 player (a Sansa e280)--even at its highest volume setting--is barely able to drive the PXC 450s at sufficient levels. I've solved this problem by obtaining an inexpensive, portable headphone amplifier.

I've worn the PXC 450s almost continuously for as long as five or six hours, without any pinching or other discomfort. This, despite the fact that to be effective, they must be worn snugly.

Great pair of headphones, particularly suitable for my frequent use of an MP3 player on public transit, or walking in a loud urban environment. (One can become too oblivious. For safety, best to use talk-through at intersections)

Better then Bose

Written By Faisal, NJ on Monday, September 17, 2007
Crutchfield Customer Review (What's this?)
 
There are many features in the PXC450 which the Bose QC2 and QC3 lack. That was good enough reason for me to select these even though price is $100 more.
The Bypass feature, the press to talk button (really handy) were just a few.
The only thing I would like more in this set is some indication of the volume level, the headset has two buttons on the side to increase and decrease the volume but there is no indication when you have reached the maximum, just keep pressing. A beep would be nice to indicate that you don't have to press no more.
Other then that they are as advertised.

Don't worry about the impedance

Written By Thomas, Denver on Friday, July 27, 2007
 
Re the concerns with impedance, the high impendace does not imply the need to use a separate amplifier. The only certain consequence of the higher impedance is that the headphones will draw less power from the source, relative to a given volume setting at the source. Most of the power will be drawn from the batteries that power the amplifier that is built-in to the headphones, using less power from the batteries that power the source component (if the source component happens to be battery-powered). If they don't play loudly enough, then using a separate amplifier might improve that, but because you are feeding a signal to an amplifier, there is also the very real potential that the boosted voltage will overdrive the amplifier, producing distortion. Furthermore, it is likely that the amplifier gain has been set so that the acoustic amplitude will not damage the wearer's hearing.

Fantastic Sound Quality and Great Noise Hushing

Written By Rich, Madison, WI on Friday, July 06, 2007
 
Very open transparent mids and highs. Deep detailed bass. Smooth sounding. Best sounding active noise cancelling headphones I've heard. Bose Quiet Comfort Series sounds very muffled in mids and highs in contrast with these guys and pales in overall comparison. No contest in sound quality. Noise cancellation as good as Bose or better. Can run in active or passive mode so your music doesn't die when your battery does.

Only downside besides being a little pricey (but to me more than worth the price as 75% of my music listening is with headphones) is the 750 ohms impedance with noise cancellation turned on. Thus, may need a portable headphone amplifier to drive with IPOD, MP3 or portable player to get sufficient volume. As the 450s are designed for travel, they are intended for Ipods, portable dvd and video players, and in flight audio but to obtain the combo of noise cancellation and excellent sound quality Sennheiser engineers probably saw no way around 750 ohm impedance. Higher impedance also preferable for inflight audio so you don't blow out your ears. But not a huge deal at all as I already own a portable headphone amp.

Great Cans

Written By Paki, LA on Friday, June 29, 2007
Crutchfield Customer Review (What's this?)
 
Great, detailed sound. The bass is pretty good and much more refined than the QC2s.
Excellent NC circuit.
Wonderful build quality
Excellent warranty.
Super features.
The bulk and size (not considerably more than other NC cans) of these was offset by my realization that their build quality and warranty would make them last way beyond anything similar from the other maker of high end NC cans.
