Bluetooth headphones often drop in audio quality during calls due to the switch from a higher-quality music playback mode to a lower-bandwidth voice mode. This switch enables the microphone function to work simultaneously during calls, prioritizing clarity and stability over audio fidelity. To mitigate this, consider using headphones specifically designed for calls or those supporting advanced Bluetooth profiles like aptX HD that maintain better quality during both music playback and calls.
