Microphone Test Online – Free, No Install

Whether you're setting up a new headset, troubleshooting a call, or just curious if your microphone still works, a quick and honest test beats guessing. This tool runs entirely in your browser, free and with no signup or download, showing your input levels in real time as you speak. It works across operating systems and devices, giving you a fast first checkpoint before diving into app-specific settings.

1. 1

   Select your microphone

   Choose the correct input device from the dropdown menu if you have more than one microphone connected, since browsers default to whichever was plugged in most recently.

2. 2

   Allow microphone access

   When your browser prompts for permission, click Allow. Without this, no input will register regardless of how well your hardware is actually working.

3. 3

   Speak normally and watch the level meter

   Talk at your regular volume and confirm the visual meter moves consistently, neither flatlining at zero nor constantly maxing out and clipping.

4. 4

   Record a short sample and play it back

   Use the recording feature to capture a few seconds of speech, then listen back to check for clarity, background noise, or unexpected static.

5. 5

   Test again after changing devices or settings

   If you adjust system volume, drivers, or switch microphones, rerun the test to confirm the change actually improved input rather than assuming it worked.
