I understand you are experiencing issues with your A40. Here are a few steps you can take to attempt to remedy the issues.

Make sure that the M80 is firmly plugged into the controller and the volume wheel is turned up and the game voice balance is in the middle.

Hard reset your Xbox One by holding down the power button until it completely powers off. You should be able to hear it click or shut down fully

Try using the provided inline cable and the headset on a smartphone and see if the sound quality has improved.
