There's a subtler issue where you can use a number of different codecs with something like A2DP. There should be a lowest common denominator of common support mandated by the spec, but you can get into fun with codec negotiation.

Yeah, I didn't mention that though because even the lowest quality A2DP codec is light years ahead of HFP or HSP which are both optimized for low bitrate monaural audio.
