I needed to make sure my headset was working before a video call, so I opened up the browser and did a quick online mic test. It's surprisingly simple—you just hit record and speak a few words, then play it back to check the audio quality. I always adjust the input volume in the system settings first to avoid clipping or being too quiet.
