To test your microphone on Mac, open System Settings → Sound → Input, select your mic, and speak. You should see the input level meter move. For a more thorough test, open QuickTime Player, choose File → New Audio Recording, and listen back to a short clip.
Method 1: System Settings (the quick check)
The fastest way to test your mic without opening any app:
- Open System Settings → Sound
- Scroll to the Input section
- Make sure the correct device is selected (MacBook Microphone, AirPods, external mic, etc.)
- Speak normally and watch the Input level meter
If the meter moves when you talk, your mic is working. If it doesn't, either the wrong device is selected or the input volume is too low.
Common trap: macOS sometimes silently switches your input device when you connect or disconnect Bluetooth headphones. If your AirPods disconnected during your last call, macOS may have fallen back to the built-in mic — and never switched back. Always check which device is selected, not just whether the meter moves.
Method 2: QuickTime (hear yourself back)
The Settings meter tells you the mic is picking up sound. It doesn't tell you what you actually sound like. For that, record yourself:
- Open QuickTime Player
- File → New Audio Recording
- Click the dropdown arrow next to the record button to select your mic
- Hit record, talk for 10 seconds, stop
- Play it back
This catches problems the level meter can't: distortion, echo, background noise, or that buzzing from the USB hub you forgot was interfering. If it sounds clear in QuickTime, it'll sound clear on the call.
Method 3: In-app audio tests
Most call apps have a built-in audio test. Use them — they check the specific audio pipeline the app uses, which can differ from the system default.
Zoom's test is the most useful because it actually records and plays back audio. Teams' test call is thorough but takes 30 seconds. Meet barely qualifies as a test.
Common mic problems and fixes
Mic not showing up at all
Check System Settings → Privacy & Security → Microphone. The app needs permission. If it's not in the list, restart the app. If it's there but unchecked, toggle it on (the app will need to restart).
Bluetooth mic connected but silent
Bluetooth audio devices sometimes connect for output but not input. Open System Settings → Sound → Input and manually select your Bluetooth device. If it's not listed, disconnect and reconnect the device.
Volume is too low or sounds muffled
Drag the Input volume slider up in System Settings → Sound → Input. For external mics, check that the gain is set correctly on the device itself. If you're using a headset, make sure the mic boom is positioned near your mouth, not pointing at the ceiling.
Echo or feedback loop
You're probably using the built-in mic while playing audio through the built-in speakers. Use headphones, or let the app's echo cancellation handle it (most do this automatically, but it works better with headphones).
How to verify mid-call (without asking)
"Can you hear me?" is the worst way to check. You break the flow, put attention on yourself, and still don't know if you sound good — just that you're audible.
A better approach: use a visual speaking indicator. Am I on Mute? Pro shows a speaking pulse that responds to your voice in real time. If the pulse moves when you talk, audio is flowing. If it doesn't, something is wrong — and you can fix it silently without interrupting anyone.
It's the difference between asking the room if your mic works and knowing for yourself before you speak.
