MBP A2DP Quality...

I just got the Motorola S805 bluetooth headphones and I'm having a bit of trouble getting them to work with my MBP. First, I'm running the latest version of Leopard 10.5.6. The headphones pair without a problem, but the audio quality is horrible and also the volume is very low.

I know the A2DP profile is being utilized because they are in stereo mode, not mono.

Also I tried them with my iPhone (3.0 beta3) and the audio quality is fine, no problem here.
Any advice?

 

anyone?
