I've been using bluetooth headsets exclusively for my gaming VOIP since as long as I can remember. With Teamspeak, I can route the incoming audio to it. Plus, of course, use the mic. And then my game audio comes from my analog speakers.
I've been using a Jabra BT8010 for a while, but I want to update to something that picks up my voice and gets rid of background audio a bit better. As far as the audio coming into my ear, it's still perfect.
