Why AirPods and Bluetooth mics sound bad on calls

When you use a Bluetooth headset's microphone, it usually switches from high-quality music mode to a hands-free mode that carries audio both ways at much lower quality. Both your voice and what you hear get muffled. The test above flags this when it sees a low sample rate.

Steps

  1. 1

    Use a different microphone

    Keep listening on your Bluetooth headphones but pick your laptop's built-in mic or a USB mic as the input. Your headphones stay in high-quality mode.

  2. 2

    Use a headset with a USB dongle

    Headsets that connect through their own USB receiver don't have this limitation.

  3. 3

    Check for wideband or LE Audio support

    Newer headsets and computers support better call codecs (wideband speech, LE Audio). Update your system and headset firmware.

  4. 4

    Go wired for important calls

    A wired headset avoids Bluetooth compression entirely.

Still not working?

  • On Windows, a Bluetooth headset can appear twice: once for stereo audio and once as "Hands-Free". Choosing the stereo device for output and another mic for input avoids the switch.
