people can’t hear me on facetime with my airpods in

Hi Grace,

Welcome to Apple Support Communities. I understand that when you try to use your AirPods for a FaceTime call the mic isn't picking up your voice, but if you take your AirPods out, others can hear you without issue. I know how important it is to be able to use your AirPods for FaceTime calls; I'd like to help. I'd recommend using the steps below to change and test the microphone settings for your AirPods:

"Open the AirPods Case, then go to Settings > Bluetooth on your iOS or iPadOS device. Tap the information button  next to your AirPods in the list of devices. Here's what you can do:

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. These set the microphone to either the left or right AirPod. That AirPod will be the microphone even if you remove it from your ear or put it in the case."

Adjust the settings of your AirPods

If you find that the microphones aren't working on one or both AirPods, use these steps next and test again: Reset your AirPods

Should the behavior continue after using these steps, reach out to Apple for additional assistance: Contact Apple Support

Best Regards.
