The latest bluetooth software and firmware updates finally enable bluetooth headsets on Mac OS X. What this means is that you can use a bluetooth headset as a regular sound input and output device selectable in the Sound Preference Pane.

I hooked up my Sony Ericsson HBH-35 headset and it worked immediately as expected. While listening to your Music with a headset is not really recommendable, it works great with iChat audio conferences. Now telephony is truely wireless, really cool.
