Stereo function fails

On my second set and it developed same problem as my first. Lower dial that controls reception/stereo feature can only "dial in" the right hand ear piece. Very very fine point where stereo feature is actually enabled but fades out and requires constant "fiddling" to find the tiny range where left hand earpiece gets reception which quickly fades out.

  • from Ottawa, ON

Great set of headphones.

Nice and comfortable. Has a wheel to adjust the signal (which reading some of these reviews, I honestly believe some people did not find). My son can watch something beside me while I am working and I don't hear anything. I can watch something which might have the occasional bad word and he can't hear anything. Sound is crisp and clear. Definitely would buy again, will likely get a second pair since you can use the same receiver with multiple headphones.

  • from Lasalle, QC

Very disapointed

A lot of noise, static and on top of that everyone around you can hear the sound. They act like a speaker for the people around you and not like headphones. I would have liked to return them but just found out about Best Buy policy regarding headphones after I purchased. Too bad for me and I will never buy headphones from Best Buy because of that policy.

  • from Kitchener, ON

ok headphones

they are just ok - comfortable - but I found a slight hiss with them, so I returned them for bluetooth wireless.

Do not reflect the quality connected with the name Sennheiser

Not impressed at all with these headphones. Will likely go back to my JVC wired headphones. Quality is poor. Bass notes are distorted and poorly reproduced. Occasional static heard along with random reduced volume and clicking noises. If I could replace them I would. Best Buy wont refund, exchange only. Even on sale they are not a good buy.

  • from Toronto, ON

Worked for about 1 year

It's all good headphone .... while it was new. Then started having noise while I was moving me head. Learned to stay still while watching......... I wouldn't buy this again. I think its overpriced for it's quality and life. Sorry Sennheiser I wish I could give a better rating and wouldn't need to shop around for another headphone just after one year of light usage.

  • from penticton bc

excellent for the money

ive had 3 previous versions of these muffs,and still have 2 for varios items ,the other set I had 8 yrs,and wore them out. excellent range and aaa batteries last a long time. I keep 2 others always charged. cant go wrong with these,and no expensive batteries to replace in the future. only gripe is the headband doesn't fit overly tight to the head ,and can fall of when bending over,but hey, fine for meI use these for radio,and tv. ide buy again,and again4.5 for me

  • from ok falls bc canada


ive owned the rs110 for 8 years,and the rs120 model for 5 years now,and have had no issues with them,i use them for ham radio listening and radio fm. battery power is excellent,and the range is amazing. all around my yard,even mowing the lawn. I keep on hand a set of AAA recharged in a separate charger,and keep rotating them when the headset ones get weak.i wanted a nice fresh set to eventually replace my worn rs110 set,and these were on sale 50 off.. they all work with the same tramsmitter too!! bonus. for the price point,and overall sound reproduction,you cant go wrong. AAA batteries are cheap and easy to replave,unlike many Bluetooth headphones from others.. I am oldschool. keep it simple

Bonne marque, bon produit, bonne qualité

C'est notre troisième paires d'écouteur pour TV Sennheiser et nous sommes très satisfait du produit et de la qualité du son. Comme ils sont tous compatibles entre eux, nous pouvons être jusqu'à trois qui écoutent le même film avec des écouteurs, pratique quand les enfants font dodo

Happy with them..Good sound

Sennheiser Head Phones

I really enjoy my head phones. They are comfortable, good sound and I can listen to my TV shows as loudly or quietly as I like. I can also walk around the house and not miss any of the dialogue.

Mauvais produit

Mauvais produit tel qu'on refuse un remboursement dans les 24 heures, incompréhensible que vous vendez un tel produit

  • from Vancouver, BC

Works fantastic!

Love them. They work fantastic! Excellent range. They work at all corners of my home. Sound quality is excellent. I am very impressed and my expectations were exceeded.

  • from BC Canada

Didn't work

Upgraded to 135 model after 125 model failed after three days. Was not digital optical as was told to me by store employee. After hooking up, the base transmitter failed immediately. Very poor power connection. Will never recommend or purchase this brand again!

  • from Vernon, BC


We purchased these headphones on the recommendation of one of the employees at the store. We have never had headphones, and he was extremely helpful and explained he difference in the different brands. He said these were an extremely good product, and we bought them on his advice. He didn't have any in stock that day, but ordered them in for us. We are very happy with them, easy to install in the tv, they are very comfortable, the audio is good high quality. We highly recommend this product. Thank you Best Buy!

Sennheiser RS 135-9 Headphones

I have two sets of Sennheiser headphones. My ordinal set RS 126 are 5 years old and still going strong, although I've had to replace the batteries. I needed a second set of headphones so I went a bought the RS 135-9 based on my satisfaction with the original 5 year old Sennheiser's. They are easy to set up and once you have them tuned in and have the volume set it's only a matter of turning them on and off. Another thing I like about them is, you can wander far away from the TV and not lose contact as with the set of Bluetooth ones I tried. Can't go wrong with these

Sennheiser over-ear sound isolating wireless headphones

Disappointed with first headphones. Had to return them because of touchy volume control. Poor quality product control, should not have been put on market. Hearing could have been damaged. Replaced the defective is ok, but controls could be better.

  • from Frankford, ON

Works Great & Dead Simple To Set Up

Was concerned that the set up would be difficult, but found it to be very straightforward and simple. Works great so far.

  • from Vancouver, BC

a necessary indulgence

I live on a very busy, noisy major street and it would be impossible to listen to TV even if volume was increased past what is acceptable in apartment living. I also have grandchildren whose programming choices are not mine so being able to share the space but not the sound is a blessing. I was happy at the comfortable fit, quality of sound and the ease of re-charging of my first pair so bought this second pair as well even if the cost was a budget stretcher.

  • from Victoria, BC

Good sound, old technology

Oer -the-ear design is comfortable, although larger and bulkier than should be. Sound quality is better than average, but not audiophile quality. Most annoying is the manual frequency tuning, which must be done frequently. Automatic tuning circuitry has been around for YEARS! I can't understand why a headset at this price level does not incorporate this most basic feature. Added to this annoyance is the close proximity of the tuning control to the volume control, and both controls are flush-mounted sin wheels. Very poor ergonomics. Also, there is audio muting when signal is lost, resulting in annoying (and) unnecessary static after only a few minutes. Another rather basic feature missing from a German engineered product. The best feature is the recharging method of resting the headset onto the cradle arms, which (fortunately) mutes the audio. Summary: Sennheizer could, and should do better. Disappointing.

  • from Montréal, QC

Good for the first 2 months

I have bought 2 pairs of these and when they're new they're amazing. After the first 2 months both sets starting squeaking (plastic noise) and the started getting static every 20-25 min. Not recommended at all.
