My brother has a stereo pair made by Coby (has adaptor to connect to computer or iPod), and I've had a couple mono ones in the past (Plantronics or whatever they're called). I've never been a fan of bluetooth stuff, as the audio quality isn't much more than acceptable, and they don't hold a charge very long (maybe 4-5 hours at the most), but my brother likes the Coby as a way to listen to the iPod while falling asleep.
If you just want wireless headphones, Sony has some 900mhz ones that are pretty good.
