I use it to multitask. I was not aware that this product is not rechargable. Now that I accept that fact, I use rechargable batteries.

Comments about Sennheiser HDR 120 - Wireless RF Expansion Headphones for the RS 120 Wireless Headphone Monitoring System:
I have a set of these. They work fine. I'm a little hard of hearing, and use them to watch TV. The only negative I have is that the TV audio has to be at a level the system will accept, otherwise it reverts to noise. That level is reasonably low. They do fall off my head when I bend over. Helpful hint: do not wear them on your head while you are washing dishes and moving a big cooking pot containing three inches of olive oil in the bottom. My headset fell off into the olive oil. I took it all apart, dumped it into soapy water, agitated it around for a few minutes and dried it in the sun. It worked great...for a couple of hours. Then it didn't, Tonight I am repeating the process, hoping I missed some grease the first time around. We'll see. Otherwise this little adventure will cost me [$] bucks.

was looking for two wireless headphones so my wife and I could watch and listen to a tv program while each of us was using the exercise equipment at the same time in our home exercise room. These headphones did exactly what we wanted with terrific sound so all could be understood, whether watching the news, espn, or a movie.

We drive the Sennheiser 120 transmitter from our mixer board in our church and presently have 7 headsets. Those with hearing loss have stated this is the clearest they have heard a service in years. We use 2 chargers to charge the headsets during the week. We could have many more headsets, the transmitter can handle them all.

My mom has low hearing. She depends on her two sets of HDR 120 headphones and wears them nearly 24/7 to listen to her TV. The HDR 120 is very comfortable and lightweight, has good sound quality, and runs for a long time on each charge. She says she can hear her TV clearly for the first time in years!

Comments about Sennheiser HDR 120 - Wireless RF Expansion Headphones for the RS 120 Wireless Headphone Monitoring System:
My wife uses these to listen to TV while walking on a treadmill.
Fortunately for me I had previously purchased a complete HDR 130 headphone set because the HDR 120 EXPANSION headphones do not come with a supporting transmitter/charger station. For me this was no issue but I didn't notice this fact in the associated marketing literature. Buyer beware.
The HDR 130 headphones I had previously purchased had suddenly stopped working and the replacement HDR 120 set work fine with the previously purchased transmitter/charger.
The only negative feature of the HDR 120 headset is that the channel has to be tuned with a rotating wheel, not an up/down switch as is found on the HDR 130 set. Since this wheel is located right next to the volume wheel, it is easy to inadvertently de-tune them.

Use this to watch movies at night with a front projection system. Purchased 4 sets and have them scattered throughout the house so I can use them in any room with upto 4 people listening to any one source at a time. Great fit. Very good sound, although can suffer from distortion on some frequencies at times, but the three options usually let you clear it up.

If you can't keep them on your head there isn't much to say about the sound. How does a company that specializes in headphones make a product that fails to meet the basic requirement? Don't bend over while wearing.
