If you are talking for communication, not just for stereo, I don't believe there is a system out there yet. The issue being, the transmitter part of the system would require to much battery power for the room in the headset. There probably wouldnt be enough room in the headsets, plus they would get heavy. Bluetooth technology isnt far enough along yet, the bandwith requirements for it are too high to get any quality out of it.
Sure they have the technology in cell phone, but that is a much broader market.
I use the Commzilla system. It is wired, and works great. The only drawback is the headsets are mono and not stereo. I bought the system through"
