How to Use an Online Mic Test Tool
Click the big blue button to begin. Your browser will ask for microphone permission.
A browser popup will appear. Click "Allow" so the test can hear your microphone.
You'll see the audio bars move and a green "Microphone is working!" message.

Why Is My Microphone Not Working?
Before you panic or start shopping for a new mic, the good news is that most microphone problems are pretty easy to fix once you know where to look. It's rarely the mic itself — more often it's a setting, a permission, or a loose connection that's the culprit. Here are the most common reasons your microphone might not be working:
Browser permission was blocked — You may have accidentally clicked 'Block' when the browser asked for mic access. Check your browser settings and reset the microphone permission for this site.
Wrong input device selected — Your computer might be picking up the built-in mic instead of your headset, or nothing at all. Head into your sound settings and set the right device as the default input.
Microphone muted in system settings — Both Windows and macOS have a system-level mute for input devices. It's easy to miss — open your sound settings and make sure the mic isn't muted or set to zero volume.
Loose or unplugged cable — If you're using a wired mic, give the cable a gentle push. A slightly loose 3.5mm jack or USB connection is one of the most common reasons a mic goes silent.
Outdated audio drivers — A recent system update can sometimes break audio drivers. Check your device manager or the manufacturer's site and install the latest audio drivers.
App-level permission not granted — Apps like Zoom, Teams, or Meet have their own mic settings separate from the browser. Make sure the app itself has permission to use your microphone in its audio preferences.
