The sound is distorted in my BeHear headset.
If you are experiencing sound distortion while multiple Bluetooth devices are connected to your BeHear headset, we recommend that you modify the default CODEC (APTX LL) and choose either the APTX or SBC CODEC instead.
This can be done in the W&H BeHear app, while your headset is paired and connected to your smartphone.
Go to the Settings menu. Choose Device. Scroll down to the "ADVANCED" section and choose the desired CODEC from the dropdown list.
Note: You will need to turn your headset off and then back on to apply the modification.
