AKG Hearo 999 II wireless headphones

Has any one auditioned these? They are really designed for surround sound, but sound like they might be pretty good for two channel listening with the advantage of being able to listen in another room.

They use digital wireless technology which should ameliorate some of the noise problems associated with wireless headphones. Has this technology really matured?

I was really wondering how they compare in audio quality to an equivalently priced (~$7-800) regular wired headphone and headphone amp set-up.

AKG makes some very good headphones. I use them in my studio. Not sure about the wireless ones though. My bigest concern would be interference from other sources in and around your home. I'd certianly ask about a return policy for those reasons. Good Luck
