• You can always use Popcall with the regular microphone built into your phone or computer.
• You can always use bluetooth earbuds (like AirPods) or wired earbuds with an integrated microphone.
• If you want to use an external mic that's not connected to a speaker, that will only work on your laptop or desktop computer – not your iPhone or Android phone or other mobile device.

On your mobile device:

External mics work with Popcall only if they are made to automatically handle both audio input and output.

✅ AirPods and similar bluetooth devices with speakers and a mic do work
✅ Wired earbuds with an integrated microphone do work
❌ External USB microphones don't work

On your laptop or desktop computer:

✅ External microphones do work by changing the audio input on your computer or in your desktop browser
