ive just purchased the ultra small nokia bh800 (9.7 out of 10 best in the market so far) and it seems i get better sound quality during calls and less when using bluetooth audio toggle is it the program and is there a alternative that works?

The problem is in using the lower audio quality (meant for voice transmission) of the headset profile instead of the high quality stereo audio you would get with A2DP. The reason it sounds better for voice calls is because they is a lower amount of information that needs to be sent (just the persons voice), and not the whole spectrum of sounds music does. I think there's a method for getting A2DP on the 2125, but of course that would require the use of A2DP BT headphones, not just a headset. The sound difference between the headset profile and A2DP is huge though.
