Have owned these for a year now. I would not recommend them. I have these at home for my PC. Everything seems to add interference. Its tollable but thats not the best thing to say about headphones. Some days just turning your head a few inchs when I am a feet from the unit is enough for them to loose signal. I don't bother to charge them on the stand, I rotate batteries between a charger and the headphones. At work I have had 2 pairs of sennheiser headphones. In 2004 I bought the RS-40. They worked great but I broke them by standing on them. Now I have refurbished RS130s that work excellently, and they run in rechargable AAA's! Neither Senn's really have the "surround sound" but I can't tell the difference to be honest. The surround sound on these is not that decernable. I think reception quality trumps surround dound in the end. I would get the RS130sBuy Acoustic Research AW791 Wireless Surround Headphones (Silver)!
