Integrating the Advanced Audio Distribution profile into Bluetooth enabled devices. By Almansor Kerroum.

Bluetooth uses profiles to define various classes of functionality. In the audio domain, earlier versions of Bluetooth provided only telephony services – the so called Headset Profile, which offered only speech quality audio. This profile was unable to satisfy the consumer craving for hifi stereo headsets, so the Advanced Audio Distribution Profile (A2DP) was introduced
Using A2DP (also called Bluetooth stereo), consumers can now stream high quality audio from portable devices – like media players, mobile phones and PDAs – to a Bluetooth stereo headset.
