left airpod mic isn't working

Hey rickey26,

Thanks for using Apple Support Communities. Since you mentioned your left AirPod specifically, check to see if your microphone is set to Always Right. If that is the case, try setting it to Automatic and test to see if that changes the outcome. You can find that using the following guidance from Change the settings of your AirPods and AirPods Pro - Apple Support.

"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."

If the same continues, does anything similar happen when you make calls on your iPhone without AirPods? If so, you can also give the steps in If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker a try since this might be related to the paired iPhone, not the AirPods.

Take care.
