Good luck. Battery powered headphones have two real problems.
Battery power isn't enough to both power the headphones to give you "excellent" quality and they sure won't last long with a quality wireless protocol.
Bluetooth is your best bet but even that isn't going to be geared towards what you want.
A lot of people want this type of thing at the store I work for. And we don't have wireless headphones for sound quality purposes. A lot can interfere with the performance. Batteries will die faster, making them inconvienent and the sound quality suffers making it not worth the effort right now.
