Ultra comfortable headphones with some static. Remember that static is common to all wireless headphones (possibly not $300+ units...never tried any at this price range for obvious reasons mainly price). Often after longer use periods 30 minuts or over, the sound cuts out and the tuning button must be pushed to connect back. Occasionally, this will not work for long and the headphones must be turned off and on again.
I found it quite difficult to find good ratings for ANY Wireless Headphones so research on many sites before you make any choices.

THE GOOD...

Ultra comfortable with the best auto size adjustment,
Easy to use buttons,
Surround Sound mode which works well with some applications,
Good charging base and easy to put on base,

THE BAD...

Lots of static most of the time,
Sound cuts out occasionally

i did the same thing another reviewer did !! i threw away the plastic armor these things come sealed in before i tested them enough !! i have never heard such static in my life !! it doesn't matter where you sit these things sound terrible !! i'm stuck with 70.00 worth of ststic!! i had retired a 6 year old set of rca's that did very good except for a loud drone in between songs,(not even noticeable on live constant cd's) guess what? their not retired anymore !!i can live with slight drones but not the constant static of these things !! beware buyer is all i can say !!

900MHz is an old technology. I owned my first 900MHz wireless headphone from about 10 years ago. Apparently, things have not improved by much. The audio quality of these headphones reminds me those really old radios from 20 years back. There are constant audio artifacts from interference such as hissing, high-pitched whines, etc.

If you accept the the fact that you are dealing with an old technology, I suppose this pair of headphones is not too bad. If you want hifi, well, you will be disappointed. The following is a list of pros and cons.

Pros:
1. Very comfortable headphones.
2. One button auto-tuning. You don't need to perform constant manual tuning like other wireless headphones.
3. Decent sound quality if you manage to ignore the audio artifacts such as the hissing and whines.

Cons:
1. Custom rechargable batteries. Don't you hate it when the manual tells you to get your batteries replaced by a dealer? Right! The total cost of replacement will probably make it infeasible.

2. Uses 900MHz wireless technology. See above. Well, I searched around for headphones using other technologies and only found infrared implementations. In this my understanding that infrared does not travel across walls, so the headphones are only useful if you are in line of sight of the transmitter.

3. Useless surround sound feature. Note that this is not Dolby Surround Sound, which decodes Dolby Surround encoded soundtracks. The surround sound feature of this headphones just makes your music sounds muffled as if you were playing it in a large room with very bad acoustics. Mercifully, this feature can be turned off.

In conclusion, buy this pair of headphones if the convenience of wireless is an overwhelming consideration, otherwise pass on it.

I bought these because my hearing is bad and I wanted to hear the TV without annoying the rest of my family. I will use them but they have a lot of distortion if the volume is turned up beyond a minimal level (on the TV). I don't have the humming that others have found and I can go anywhere in the house without much loss.

However, the sound quality isn't there. It is way too high on treble and the distortion is annoying. I'd return them but I had to butcher the box plastic sealed box to get them open and then threw the box away before I tested them enough.

I ordered these headphones about a week ago and find that when they work, they have excellent quality. However, do not be fooled, they fail to work most of the time. After charging these headphones for a full night, I have tried listening to them this morning. I have moved the base to several different areas, and I have tried all the 3 channels to try to get rid of interfernce and static. Anytime the headphones pass within a straight line of the transmitter, you come across major static. After changing channels and listening to the headphones for 20 minutes, they begin to go into massive static yet again. Nothing works to help the performance of these headphones. Full charge, changing position. Not to mention that the headband "adjustment" strap is nothing more than an elastic band. It is not terribly comfortable. The surround sound mode is rather useless too. It just pumps in more treble into the sound. Finally, the volume varies widely. Each song is being adjusted as being too loud or too soft between songs on the same CD. Unfortunately, I cannot recommend these headphones at all.
