I bought this headset to replace a radio shack wireless headset where the batteries were failing. I like the Sennheiser for its quality, the fact that it sounds great and for the fact that it uses AAA rechargeables (comes with it) that will hold a charge for more than 24 hrs of use, and they are easily replaceable when that time comes. The sound quality is excellent... good bass and the highs are clear. I use these primarily in bed so as not to disturb the wife while watching TV... I am one of those who needs the noise in order to sleep, so the headphones are on all night albeit at low volume. I have found that they are cool and comfortable to wear. I wake up without the red ears I used to get with the others. If there is a complaint it would be that they fit on the ear and as such feels loose on the head, so when I do use them while moving about they slip. The old set was around the ear, so was more secure, but after a couple of hours were intolerable to wear... tradeoffs. Oh, one other thing I discovered that I really like is that the ear cushions are easily removable and can be cleaned with a mild detergent, dried and snapped right back on. So, bottom line, I am very satisfied with these and recommend them to other night owls or those who need to wear them for long periods.
I love these headphones 2006-12-11
I have had my Sennheiser HDR120 headphones for almost a year now. Whereas I often have trouble hearing speech clearly coming straight from the TV, with these headphones I get crystal clear sound. I like being able to roam around the house and not miss a word of sound. I have demonstrated these to numerous friends, and their most common reaction is, "I gotta have a set of those."
So close, yet so far.

I've been using these headphones for about 3 months now. I initially bought them to use at my work, but have since brought them home because the interference there was too high.
Tuning them is difficult, but in a lower interference environment once you get them set you typically don't have to play with it. It's pretty much impossible to get rid of a slight hiss though.
The biggest problem with these headphones is the automatic turn-off of the transmitter. After 5 minutes of silence, the transmitter shuts down. The headphones then burst into static because they're no longer receiving a signal. It's pointless since the headphones are still wasting battery and the transmitter is plugged in, and god forbid you be doing something where sound isn't absolutely consistent.
I could handle the tuning issues as just being part of the wireless game, and I love the freedom of being able to just leave my headphones on when I need to go do laundry. But really, the transmitter cut off makes these equal parts delightful and irritating.
Great headphones at a great price! 2005-09-04
I can't believe the quality and usable distance of these headphones. I hear nothing but quality sound. I have heard no hissing and no fade. The controls are easy to use and the sensitivity makes whatever you're listening to, sound like your listening to it live.
Freedom, but at the cost of quality 2005-05-05

I bought these headphones in February and have greatly enjoyed them. I walk all over my house, single story 1700 sf and never have a problem. I use them mostly for TV and music. I have not experienced any reception problems or high pitched buzing like others have. I recommend these headphones.
The hissing will drive you mad! 2004-12-25
I bought these headphones, hoping that they will allow me the freedom to move around the house while still being able to hear the stereo. These headphones do have great range: I was 50 feet from the base, with two walls of separation, and could still hear the sound as clearly as when I was right in front of the base. Unfortunately, the clarity of the sound, even when you're right next to the base, is not very good. A high-pitched whistle pierces my ears, and I just had to return the headphones. I don't recommend them.
