Bluetooth kennt zwei Profile für die Übermittlung von Audiosignalen: SCO und A2DP. Beim SCO-Profil handelt es sich um eine Zweiwege-Verbindung mit schnellen Reaktionszeiten (tiefe Latenz) zur Übertragung von Gesprächen. Es überträgt Töne in der Regel in Mono-Qualität, mit dem SCO-Profil lassen sich sowohl Töne empfangen als auch senden.

The bandwidth of bluetooth cannot accommodate uncompressed high-quality stereo audio, so the audio stream must be digitally compressed. Pausing, playing, advancing the track are features of the AVRCP profile, most commonly combined with A2DP.
