Question: are there microphones in both airpods?
Answer: 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.
