It’s been a while (few years actually) since I even tried, but bluetooth headsets just won’t play nicely. You either get the audio quality from a bottom of the barrel or somewhat decent quality without microphone. And the different protocol/whatever isn’t selected automatically, headset randomly disconnects and nothing really works like it does with my cellphone/windows-machines.
YMMV, but that’s been my experience with my headsets. I’ve understood that there’s some propietary stuff going on with audio codecs, but it’s just so frustrating.
