How to Check If Your Microphone Is Working — Free Online Test

⚡ Quick Answer

To check if your microphone is working, open a free browser-based mic test tool, allow microphone access, and speak. If the volume meter responds to your voice, your mic is functioning. If there's no movement, the issue is likely permissions, the wrong input device selected, or a driver problem.

"Can You Hear Me?" — The Most Frustrating Question in Tech

You join a meeting, a voice chat, or a recording session — and nobody can hear you. Before spiralling into panic mode, do one quick thing: test your microphone online. A browser-based mic test gives you immediate, visual feedback — you can literally watch the meter respond when you speak.

👤 Real-Life Scenario

Priya, a freelance translator, couldn't be heard during client calls. She'd reinstalled Zoom twice. Using a browser mic test, she discovered the tester was defaulting to her laptop's internal mic — but she was using a headset. She switched the input device and suddenly her voice came through clearly.

How to Test Your Microphone Online — Step by Step

  1. Open the Microphone Tester — Compatible with Chrome, Firefox, Safari, and Edge on any device.
  2. Allow Microphone Access — Click Allow when the browser prompts. If you don't see a prompt, check the address bar for a blocked microphone icon.
  3. Speak Into Your Mic — Say something clearly and watch the on-screen volume meter. If it moves, your mic is working.
  4. Check the Input Device — If you have multiple microphones, use the dropdown to switch and test each one.

Volume Meter Doesn't Move At All

Make sure you clicked Allow for microphone access. Then check OS-level permissions: Windows: Settings → Privacy & Security → Microphone → Turn on access. Mac: System Settings → Privacy & Security → Microphone.

Mic Is Detected But Volume Is Very Low

Windows: Right-click the speaker icon → Sound settings → Input → raise the input volume slider. Mac: System Settings → Sound → Input → drag the Input Volume slider right.

Mic Works in Browser But Not in Zoom/Teams/Discord

This is an app-level permissions issue. In Zoom: Settings → Audio → Microphone. In Teams: Settings → Devices. In Discord: User Settings → Voice & Video → Input Device.

Echo or Feedback in Mic

Your speakers are too loud — the mic is picking up speaker output. Use headphones to break the feedback loop and reduce mic sensitivity in your OS sound settings.
