Why do dual-channel bluetooth headsets have a significant drop in sound quality and become mono when using the voice function?
Reason:
Bluetooth headphones use the A2DP protocol when listening to music, watching video and playing games. The full name of A2DP is the Advanced Audio Distribution Profile bluetooth Audio transmission model protocol.The protocol uses a chip in the headset to stack data, allowing the transmission of sound in high definition.When using this protocol, the stereo sound can be reflected, double channel can be realized, and the sound quality is full and clear.However, this protocol does not support voice communication.When the voice function is enabled, it will automatically switch to the HFP/HSP protocol,so that the bluetooth device can support voice communication, but cannot carry high sound quality and stereo.So that's normal.
