Microphone Not Working/ Others Can't Hear Me. How to fix?

If you can hear sound through the headset, but can’t use the mic, please check according to the following steps.

Step 1: Please make sure the boom mic hasn’t been mute on and has been plugged tightly into the headset.

Step 2: Please check the sound setting on your audio source (computer/PS4 or Nintendo Switch), make sure that you have set the C519M as both input/output devices. 

If the above still doesn't help, please contact us at support@avantree.com.
