I need my both microphone to work on my AirPods

Set Microphone to left, right, or automatic

There's a microphone in each AirPod, so you can make phone calls and use Siri. By default, Microphone is set to Automatic, so that either of your AirPods can act as the microphone. If you're using only one AirPod, that AirPod will be the microphone.

You can also set Microphone to Always Left or Always Right. You can also set Microphone to Always Left or Always Right to always have either the right or the left AirPod use the microphone even if you remove it from your ear or put it in the case.
