What Are Bluetooth Profiles?

Bluetooth devices do not all work in the same way. One device may not work with another (such as a Bluetooth phone with a Bluetooth computer, a Bluetooth headset with a Bluetooth music device, etc.) This is because there are a number of Bluetooth profiles, which can change the performance of your headset.

More information about Bluetooth profiles can be found below or at this website.

HSP – For voice and mono music, e.g. Skype: (Headset Profile)

This is the most commonly used profile, providing support for the popular Bluetooth headsets to be used with mobile phones.

HFP – A more advanced version of HSP (Hands Free Profile)

*Allows Voice Dialing Activation + Redial + Call transfer + call answer/end capabilities

A2DP - For stereo but no voice: (Advanced Audio Distribution Profile)

Also referred to as the AV profile, it's designed to transfer a stereo audio stream like music from an mp3 player to a headset or car radio. This profile relies on AVDTP and GAVDP.

AVRCP - For remote control: (Audio/Video Remote Control Profile)

This profile is designed to provide a standard interface to control TVs, Hi-fi equipment, etc. to allow a single remote control (or another device) to control all of the A/V equipment that a user has access to. It may be used in concert with A2DP or VDP.
