Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
Sennheiser RS-65
I would ditto all of the other reviews; this is a good set of wireless headphones.  The only downside is that after using them for a couple of months to give a decent review, I read that I should have received a second battery that wasn't in the box (it does say it on the box, but no mention in the instructions).  No big deal for a $20 battery though.  It is worth noting that they use a proprietary battery vs. something you can buy at Radio Shack.  I am happy with the purchase.
