Nope, doesn't work. Apple hasn't provided a "headset profile", which means Mac computers won't be able to handle headsets. Yet. Maybe in the release version of Panther.
If they include a headset profile, any Bluetooth headset will work.
Mind you, you can already detect the headset, and you can pair your computer with it, but it won't show up as a sound source or sound output device. The computer and the headset will talk to each other, but none of them will understand the other.
And yes, I've tried.
