What is A2DP (Advanced Audio Distribution Profile) - Definition?

A2DP stands for Advanced Audio Distribution Profile. A2DP is a Bluetooth profile which describes how stereo-quality audio can be streamed from one device to another over Bluetooth. So, it helps in streaming music wirelessly to headphones or speakers over Bluetooth. Both devices needed to have this A2DP profile for this to work. If both devices do not contain this profile, you may still be able to connect using a standard Headset or Handsfree profile, but it will not support stereo music.

A2DP is one-way only and streams a stereo signal.
