Result

This page opens the mic test in playback-check mode: start the test, record a short clip and immediately hear yourself back.

Hearing your own recording is the fastest way to judge what other people get on calls: muffled sound, echo, background noise or a microphone that sits too far away. A five-second clip is enough to catch all of it.

The clip is created with MediaRecorder right in your browser and stays on your device — nothing is uploaded, and closing the tab discards it. You can also download the clip if you want to compare microphones.
