Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Good sound - poor durability
I have now owned two sets of wireless Sennheisers, the RS-65 and the prior design, the T4-9.  Sennheiser has made great design improvements in the past few years, especially regarding comfort. Specifically, the prior version had a flat foam surface that pressed against your whole ear.  This version has a velvet-like cup that surounds your ear without pressing it into your head. It's interesting that some people say they are uncomfortable. I disagree - I find them light and reasonably comfortable.    The sound quality is good, but there is an important caveat: wireless headphones always come with more static than wired headphones.  I found that it was not a problem when I was in the same room as the transmitter.  In the old version the static would increase slowly as you walked away.  The RS design blocks noise until a threshold S/N ratio is reached - then there is no sound at all. It would be nice if you could choose that functionality because when I'm using them for the TV it's more important to at least hear something than to hear clear sound and then no sound.    MY BIG COMPLAINT: The first Sennheisers I owned lasted for a year and then the structural headband broke. They still worked but you had to tape them up.  The second Sennheisers I owned lasted for a year and then, you guessed it - SAME PROBLEM. I'm not knocking these things around, just taking on and off. For expensive headphones, these are just not made well enough.    I don't know if I would buy Sennheisers again without evidence that the band was made better. I strongly recommend you buy them with an extended warranty.    UPDATE: I have since moved into a city from a sparsley populated suburb and have found that the interference from neighboring buildings makes it impossible to use these.  If you live in a densely populated area, be aware that you may need to return them because of transmission difficulties.  However every area is different.  I would only buy these again if a new model used a more advanced transmission  scheme like 2.4GHz, and of course, if it appeared they had redesigned the headband.
