HSP (Handset Profile) and HFP (Hands-Free Profile) Bluetooth profiles are those required for typical, mono Bluetooth headset operations; A2DP and AVRCP are important for stereo headsets. A2DP (Advanced Audio Distribution Profile) - allows the transmitting of stereo audio signals (with much better quality than the mono encoding used for HSP and HFP). AVRCP (Audio / Video Remote Control Profile) -is used for sending commands (e.g. Skip Forward, Pause, Play) from a controller (e.g. stereo headset) to a target device (e.g. PC with Media Player).
