I Do NOT Love Products

Written By SR S, Bloomington Springs, Tennessee on Sunday, November 27, 2011

Crutchfield Customer Review (What's this?)

What I do not like about these headphones is: when I look down they slip off. Also, when a source signal is not present, the headphones play white noise instead of dead air. Playing the white noise is work that wears on the speakers unnecessarily. I like these headphones because they have no cord to limit my movement or to catch my arms in motion, and they produce excellent sound quality regardless of the source. Despite those two minor issues, I recommend them to anybody who wants quality sound reproduction from a well designed convenient package. Now I can listen to my music or the news anywhere I am on our twenty-four acre farm.

Pros: I do not love products. I love people and animals. I like these headphones because they have no cord to limit my movement or to catch my arms in motion, and they produce excellent sound quality regardless of the source.

Crutchfield Customer Review (What's this?)

I purchased these as an aid for hearing loss . They are working great in that respect. The only reason I did not give them a 5 star rating is that the fit is not a tight fit.Other than that I would highly recommend these. Very satisfied!

Thank You!

The best wireless headphones in the market

Written By Dr. John, Miami,Fl on Thursday, March 10, 2011

Crutchfield Customer Review (What's this?)

I was looking for a headphones that let me listen to my music and videos while
I may continue working ( I run an office in my home), and tried several ones
before I get this Sennheiser RS 120, the sound quality is marvelous, the
extension of the transmitter is also very good, no interference at all, and now
I'm telling all my friends that this is the best headphones in the market for this

Great range

Written By Dan, Lake City, FL on Thursday, February 03, 2011

Crutchfield Customer Review (What's this?)

Just what I needed to continue listening to the radio while working in the woodworking shop or working outside. Many years ago I bought a similar product from but it didn't have the range to work outside and no longer works very well inside either. The outside range of these headphones is about 300 feet!
The cons, will fall off with activity but that may just be my head.

I told my Crutchfield advisor (Tony) that we wanted some basic, wireless headphones -
descent quality, comfortable and primarily for TV programming - sports and movies. As he
has since he helped us with all the gear for our new house 3 years ago, "he nailed it."
Thanks Tony. Thanks Crutchfield.

Nice, lightweight, easy to use headset. Work well for my dad who walks on a treadmill with

Great sound, minor annoyance

Written By Richard E, MIddletown, CT on Monday, January 24, 2011

Crutchfield Customer Review (What's this?)

These headphones perform remarkably well. The sound quality is astonishing--
among the best I have heard from any headphones. The range is impressive; no
problems with interference or weakening signal.

As others have noted, it is very easy for these headphones to fall off your
head. Forget bending over, not gonna happen. The ear pads come off easily,
maybe too easily. They can come off accidentally.

These are minor complaints. The performance of these phones is first rate.
Hold them on your head if you need to bend over. But buy them.

Great for the price

Written By JeffM, Atlanta,GA on Monday, January 24, 2011

Crutchfield Customer Review (What's this?)

Having read some of the other reviews I had reservations on this pair but the next price
up was a big step. I went with these. The package came quickly without any problems.
They were easy to hookup with clear instructions. We have a seven speaker sound
system in our living room but with young kids that go to bed early I wanted something to
keep the noise down on the TV. I was very impressed with the sound quality. Crisp
clear sound that even beats our sound system. I did notice that the felt covers on the
ear pieces are very smooth and any sudden movement will send them flying off your
ears. I would not attempt to wear them moving around the house cleaning or trying to
exercise. The reception is good but will at times, completely drop out, leaving a loud
buzz in your ears. I can walk outside and move around my yard, with occasional dead
spots to be found. That range is about 100 feet. Yes, the side controls are confusing.
The volume and the tuner are both thumbwheels mounted vertically, one after the other.
It's easy to forget which one is the volume. If your looking for a pair to sit and watch TV
quietly or listen to music these are great. If your needs are for a more active mobile
solution, then these probably will not fulfill the requirement.

complaint would be the fitting of the headphones, bend slightly forward and you have to hold

Earphones for RS120

Written By Jack T, Yuma, Arizona on Sunday, November 28, 2010

Crutchfield Customer Review (What's this?)

The headphones on the new RS120 are not as good as my former model. While there
is more clarity on the sound portion the ear part seems to be much cheaper and
do not fit the ear well. Almost like some earphones on airline equipment. I was
a little disappointed.

serious problem

Written By RobertL, Seattle, WA on Friday, October 29, 2010

Crutchfield Customer Review (What's this?)

I use these headphones to listen to the TV while moving around the house. I am
pleased with the performance of the system such as sound quality, range and battery

However, if I move my head even slightly the actual headphone will jump off my head.
This seems to be a common complaint with this unit.

I use other Sennheiser wired headphones and am pleased with them.

This product needs some redesign.

recharing the batteries.

Very satisfied

Written By Dave, Fairbanks, AK on Saturday, October 09, 2010

Crutchfield Customer Review (What's this?)

A very satisfactory product. 'Good range, good sound, and well designed. The recharge stand makes it easy to keep powered, and it uses standard re-chargeable AA batteries. There is a very low level, ever so slight hum in my unit, but I've tried and cannot hear it while music is playing. During long silences in TV dialogue however, it becomes apparent. Its volume is so low I do not find it distracting. I found the ear pads a little surprising. They look like over the ear headphones, but the pads are flat -- so they lie flat on the ear. This keeps your ears cool, but also allows some sound bleed that may be annoying to others in quiet rooms. If that's not a big problem, these headphones do everything well.

good for the job

Written By Mark, Hagerstown on Wednesday, August 18, 2010

Crutchfield Customer Review (What's this?)

Got these so that the user could listen to TV at odd hours without distrubing other members of the household.

Sound is good. We, all three, agree that the conversation comes thru better than thru the Bose Lifestyle v20 surrond sound speakers.

All agree that the comfort level is acceptable, with one saying that there is a bit too much squeeze. All agree that if you have to bend over, as to pick something up from the floor, that they tend to fall off.

Head Phones

Written By lchace, Alaska on Thursday, December 10, 2009

I love these head phones, the sound quality is beautifull and far superior to ones I've used in the past. They seem to stay charged overnight. The installation was easy.. I find they are a bit loose on my head but the sound makes up for it, they are not the airplane noise reduction type but ones that just sound wonderful.

Great for workouts

Written By Michael, Loveland, CO on Tuesday, April 21, 2009

Crutchfield Customer Review (What's this?)

I purchased the Sennheiser R120 for one purpose only - to workout on the treadmill. I like to watch the big screen while on the treadmill and I've had to crank up the volume so I could hear it over the treadmill noise. As a result, it drowns out every other TV on in the house. I studied the various wireless headphones and chose this one based on a number of factors. Now that I have it, I can hear much better than I could by cranking up the volume. The sound is crystal clear and in stereo. The rest of the house is now quiet. Great choice.

Great product but....

Written By Rodney, Aldan, PA on Monday, February 09, 2009

Crutchfield Customer Review (What's this?)

The sound is good, but the bass is not great. I simply adjust the bass on my receiver when I wear them. If you plan on doing yard work or working out, these are not for you. They often fall off if you bend over. This is not a problem for me though, because I primarily use them for late night TV watching. I don't get much static, and if I do, it is easily adjusted with the tuning dial. As far as comfort, I forget that I have them on at times. I would have given them a fivestar rating, but the occasional static and lack of deep bass only merits a four to me. I must say though, I would rather deal with minor shortcomings than to be tethered to my receiver. One last thing. Crutchfield delivered them in two days which seems to be standard with them. My three previous orders of other equipment also arrived in two days.

Worth the money

Written By Stan, Los Angeles, CA on Sunday, February 01, 2009

Crutchfield Customer Review (What's this?)

The RS20 has been a pleasure to use. I haven't encountered the problems some reviewers have found: hiss, short range, etc. I get a bit of hiss when the RS20 is turned on, but it's gone in a couple of seconds, and the sound from then on is perfectly clear. It may not be the highest of fi, but it's plenty high enough for me. I've used the headphones at a distance of a couple of hundred feet, and they work fine.

The only problem I've had is recharging. Just hanging the phones on the cradle doesn't turn on the red charging light the way it's supposed to. I don't know if it's a design error or a defect in my phones, but it isn't worth sending them back for it. I just put a weight on the phones and the red light stays on. I guess I could call support and see if they have a remedy. The use of a large packing box filled mostly with non-recyclable peanuts is my worst criticism. Otherwise, I love Crutchfield and these phones.

[Editor's Note: Please note that we use only biodegradable starch packing peanuts in our warehouse. We cannot speak for the packing peanuts our vendors may use.]

Sennheiser Sensation.

Written By Harlan, Elm Grove, WI on Wednesday, October 08, 2008

Crutchfield Customer Review (What's this?)

I've replaced another Sennheiser model I had. The RS65. This one though is much improved & even less money. They fit very well over the ears. Very comfortably and snuggly with no cauliflower ear feeling. Crisp, clear sound.

We use them primarily with a Sony Bravia XBR4 32" HDTV for sound. Easy installation, hook up to our audio jacks (RCA jacks/red, white I believe) on the DVR. Great when your mate's asleep. They perform quite well I might add also. The range is very good and easily adequate.

I rarely experienced the static. The bass isn't bad but don't expect the thumping & pronounced bass you've always dreamed off. They hang up easily for recharging with their included battery after its use. I highly recommend these. A very good value overall.

Written By ddenoon, Olathe, KS on Sunday, August 24, 2008

We had an infrared headset with our former Sony and my husband enjoyed it so much that a wireless headset became a necessity with our new TV. He says that this new headset is more comfortable and he wears them anytime we both watch TV. It really reduces the number of times he is asked to turn down the volume because he can turn up his volume as loudly as he wants. Very satisfied with this product.

Repeat Business

My wife originally bought this product for me for Christmas 2007. I have thoroughly enjoyed it and use it several times a day (i.e. a must to listen to things other than my kids' viewing of Spongebob, etc.)! We live in a more rural area and I can listen while walking the dogs--the range is a little greater than the specs advertise. The band connecting the phones recently wore out and I reordered the same product!

Great for watching tv while on the treadmill

Written By jtrapp77, Santa Rosa, CA on Sunday, April 15, 2007

Despite all the mixed reviews I decided to purchase these since I have never dealt with wireless headphones before. I wanted to be able to hear my tv while walking on the treadmill without having to turn up the tv to an extreme level. The sound quality is great. I can hear the shows I'm watching so well that I don't even hear the treadmill itself. The only downside is that the headphones completely cover your ears and feel bulky. I'm used to headphones I can stick in my ears. These make it hard to stay cool while exercising since they cover so much area.

Poor design

Written By Bob, San Francisco, CA on Tuesday, January 30, 2007

The mediocre performance was a surprise, I was expecting more. Certainly not the poor reception or the constant hissing. Adding insult to the poor performance was the poor desing of the headphone itself. With light use it broke!

Don't buy it.

Previously I have a RCA 900MHz wireless headphones and it sound well but it broke, 5 years of service, and I want another with more range. I choose the Sennheiser RS 120 for it specs but it don't produce bass and the sound quality is worst than my earlier wireless headphones. If walk a 20 or 25' it distort the sound. Is my first shop in Crutchfield that I'm very deception. The only positive feature it has is the battery life and charging time. Don't buy it for any reason.

Excellent Choice

Written By Gary, Montana on Saturday, May 07, 2005

Having some hearing loss I chose wireless headphones so my wife could enjoy TV at a reasonable volume. This model was chosen due to the many rave reviews I have read and they were right-on.

Extremely easy set-up to a TV, dish, DVD, VCR, headphones jack, or the "Tape-Out" RCA jacks of a receiver for hearing all components. It comes with two gold adapters and all you would need. Easy recharge by simply setting them on the attractive charging stand; it could not be easier. Quick tuning with no interference, 3 channels, smooth volume adjustment. Excellent range throughout my large house; steady sound to the kitchen, bathroom, through four rooms, out in the hot tub, and up and down the stairs. High quality stereo sound. Sturdy, well-made, comfortable weight and earpad design. Two replaceable, easy-to-find, long lasting AA NiMH batteries that do not develop memory when recharging after short use.

I am very happy with this investment, and my wife is, too.

Product Research



Open-Air, Supraural On-the-ear Design: Sennheiser headphones adjust to the shape of your head, with their joints, flexible materials and extendable arms. Comfortable cushions provide optimum comfort in those places where sturdy material would rest on your head.

Transmitter/Recharger: The system comes with an RF transmitter that connects to an audio source via preamp outputs. Its transmission range is from 926 to 928 MHz. It transmits a signal to the headset, using one of three selectable transmission channels. With this powerful transmitter, your crystal clear listening range is up to 328 ft. The transmitter has an automatic On/Off function. It switches on and begins transmitting when it detects an audio signal, and will switch off if it detects no audio signal for 3 minutes. The transmitter also functions as a storage stand/charger for the headset's NiMH rechargeable battery when not in use. This unit also has overcharging protection. There is a keyhole slot on the back of this transmitter for wall mounting.

Headset: The headset features cloth ear pads for listening comfort. The left ear cup has a compartment for the user replaceable rechargeable battery, and an On/Off switch. On the right ear cup, there is a tuning control for tuning the headphones to the base, and a headset volume control. The headset also has contacts that allow the battery to be recharged when the headset is placed on the transmitter/storage stand.

Rechargeable "AAA" Batteries: Power for the headset is provided by two "AAA" rechargeable batteries that fit into a compartment on the headset (supplied). The batteries in the headset are recharged whenever the headset is placed on the transmitter/storage stand. Fully charged batteries have an operating time of about 20-25 hours. The manual recommends an initial charging of 24 hours before the batteries are first used, after that the normal charging time is approximately 18 hours. Note: Only rechargeable batteries should be used.



  • Channel Switch: allows you to select transmission channel 1, 2 or 3
  • On/Off: Green LED indicates whether the unit is on or not
  • Charge Indicator: A red LED will illuminate when the battery in the headset is being charged


  • Volume Control: allows you to adjust the volume of the headset
  • Tuning Button: allows you to tune the headset for the clearest reception
  • On/Off Switch: turns the headset on or off



  • Audio In: this cable is permanently attached to the transmitter, with stereo male RCA connectors at the other end.
  • DC Input: for use with supplied AC adapter


  • Charging Contacts: interfaces with charging arms on transmitter to charge the "AAA" NiMH batteries.



  • Carrier Frequency: 926-928 MHz

  • Modulation: FM stereo

  • Frequency Response: 22-19,500 Hz
