I bought these headphones a few years ago from amazon, I had been looking to buy some wireless headphones for quite some time and these seemed to be a nice jumping off point.
The first thing i noticed about about these headphones was how uncomfortable they were, the headphones felt really stiff on my head and it became apparent after a few hours of use that the headphones began to hurt my ears.
Comfort factors aside these headphones did it's job and sounded good, at least while I was siting fairly close to the transmitter, i found out the hard way that moving too far away from the transmitter produced a horrificly loud hissing sound in the headphones.
There is one other reason i gave these headphones such a low rating and that is the battery life, if you use headphones heavily and don't have rechargable batteries this thing will have you buying a TON of batteries.
Maybe i'm just too used to good wired headphones but i was fairly let down by this product and would'nt recommend it.
