Sennheiser  RS-65 Wireless RF Circumaural Headphones with SRS Surround Sound Processor (Black)
These have worked great so far.
I purchased the SR65, and been using them for an hour so far. The sound is great for wireless headphones. No distortion of crackle, and Im sitting about 15 ft away from the base. The base sits behind the TV, so it's not in direct view of the headset. I get a litle crackle when I go in the next room, but it only does it for  less than a second and then it sounds just fine. I was going to buy the SR85 when Amazon had it for 169.00 but decided against it.  If you are undecided about what model to get, my vote is for the SR65.  Will see about the comfort level, I have a small head and they feel very cormftable so far. <BR>Very satisfied.
