This one, but with a 4-pin (stereo+mic) format that's compatible with at 
least 1 major vendor (so that "DIY" means "buy an adapter from a web 
store" rather than "fire up the soldering iron").

See for example:

Offtopic gripe - Bluetooth headsets are OK if they work, but so far I 
have been unable to get my GTA01 to talk to one (it pairs, but I can't 
get audio through it). I posted a query on device-owners and did not 
hear any other success stories. I hope that OM has done enough QA 
testing to guarantee that this is only a Linux software issue and that 
the Freerunner (at least) will eventually have full BT headset support.
