Sound cards and phones use two different Bluetooth profiles, Advanced Audio
Distribution Profile (A2DP) and Headset Profile (HSP). The main difference
between them is that HSP provides signaling to answer and hang up calls etc,
and it uses a codec that sounds lousy. A2DP, on the other hand, sounds
pretty decent.

Do these allow you to pair with both devices using A2DP, or only one device
with A2DP, and the other with HSP?
