Sorry but I will only warn you off from entering this tar pit. While it is all too easy to get the right hardware for this, finding and getting A2DP (http://www.google.com/search?hl=en&source=cnet&q=A2DP ) will be your biggest challenge and I decline to write more about that.

But to the hardware side almost 99% of the dongles out can get the bluetooth audio link support. Just you should see 99% of the time failures getting A2DP working. Simple audio was a snap.

A2DP was a tar pit so I'll leave you with that.
