Poor product

Purchased this product as recommended from Employee. Did not get what I asked for. Base unit quit 3 days later. Found out base quitting is a common occurence

Waste of Money. Not Recommended

1- Difficult Assembly. The power cord on the base is difficult to plug in and keeps sliding half the way out by itself. 2- They easily fall off your head if you look up or down 3- Poor sound quality, there is always static noise 4- Manual tuning! Why?! I never need to manually tune the speakers of the TV. Why can’t these headphones just give me the same sound coming out of the TV? 5- Base turns off by itself. This is extremely annoying. I am often watching a movie or a game and all the sudden the headphones scream shshshshshsh because the base decided to shut off. Unplug the base from TV then reconnect, it would work fine for 10 minutes then the same thing happens again.

Didn''t last long

Had them about a month and then base station died. No idea if it was the power cable or the unit itself. Not the most comfortable headset either. At least BestBuy was able to give me store credit...I'll go and buy something else (probably another brand) on Black Friday. The CS rep at the store claims they no longer carry them in store and can only get them online...wonder if that's a sign they are being phased out.

Worth the money easily

If they were as comfortable as headphones priced three times as much I would have given them 5 stars. But as they are-they are fine. Sound is surprisingly good even when listening to music. For catching a movie or a TV show- they are perfect. No need to buy the higher priced Sennheisser wireless model simply for the optional headset charging stand. Best of all, if you have a set of audio out jacks on your TV set, then you can plug in the included RCA audio cable into the TV, from the transmitter and listen on your earphones, as loud as you want, while someone else can listen to their choice of volume from the tv simultaneously, and not influence your volume. Range is very good and have had no crackle, dropout, or white noise to speak of while wearing them.

Big design problem

The electrical cord plug on the base has the worst design. It's hard to put it in and it disconnects often. The worst thing is that BestBuy doesn't accept it as a return reason, they just exchange it with another one. It took me 30 minutes to convince the customer service guy that the headphone has a problem. Nice customer service BestBuy!!!

Sennheiser 125

Very good product. Problems with reception background noise at first and then changed the channel and now are perfect. Tuning is great and volume control works fine as well.

  • from Kingston, ON


Although the bass comes through almost too well, the treble and mid-range are very weak. Occasional pops and crackles that are not part of the program tend to be disconcerting. Will sometimes lose signal strength if the headphones move on your head. Uses up batteries relatively quickly. If the signal is lost; i.e., turn off the receiver or TV and the white noise that comes through is not pleasant. Could be more comfortable over the ears. Given the name brand, I was expecting a bit better quality. Unfortunately, I was disappointed.

Easily falls off your head and not very comfy

These sound pretty good and does not cut out like my Sony's. They are not very comfortable and will easily fall off your head if you tilt up or down. Made of very cheap plastic. I upgraded to the covers my ears set and are much better fitting!

  • from Montréal, QC

Poor reception

These headphones were hard to pair with the base. They always had static so I returned them. Also, I had to unplug them from the TV after each use so that meant getting out of bed. I would not recommend them.

  • from Brampton ON

so far so good

Not bad quality for the price. Range is very good. Not overly happy with the manual tuning. Batteries don't last super long time.

Sennheiser Wireless Headphones

Great headphones. Allows you to listen to TV and music while roaming around the house and outdoors. They have good range.

Sennheiser RS 135 wireless headphones

I've been using this product for many years & it is very good. I am quite deaf & these headphones do the job. The sound is clear & they are easy to set up. They do have a shelf life though, which is true for all things electronic....usually about 5 years. I am about to buy my 3rd set & am happy to do so.
