Each tone should come from the matching earpiece. When both sides check out, move on to the microphone.

Headset test: check your headphones and mic in one flow
This headset test walks you through checking both halves of your headset in one place: first the earpieces, then the microphone. Play tones to confirm the left and right sides work and aren't swapped, then speak to see your mic's live level and record a clip to hear yourself back. It's the fastest way to make sure a gaming or call headset is fully working before you join a meeting or game, all in the browser with nothing uploaded.
Step 1: test the earpieces
With the headset on, play the left-only and right-only tones and confirm each sound comes from the correct side. Swapped sides usually mean the headset is wearing the wrong way round or the audio channels are reversed in your settings. Playing both together should sound centred. This also confirms your headset (not your speakers) is the active output device.
Step 2: test the microphone
Grant microphone access and speak normally. The level meter should rise as you talk; if it stays flat, the wrong input is selected or the boom mic is muted. Record a short clip and play it back to check clarity and background noise. Everything is processed on your device and never uploaded, so it's private.
Common headset problems
If only one side plays, check the plug is fully seated. A headset half-inserted into a combo jack often loses a channel or the mic. For USB headsets, make sure the headset is selected as both the output and input device in your system settings, since it can default to only one. A mute switch on the cable or earcup is a frequent reason a mic seems dead.
Everything runs in your browser
The tones are generated locally and the microphone audio is analysed on your device, nothing is recorded to a server or uploaded. Start at a comfortable volume, especially with a headset, to protect your hearing.
Frequently asked questions
Use the two-step flow: first play the left and right tones to confirm both earpieces work and aren't swapped, then grant microphone access and speak to check the mic level, recording a clip to hear yourself back. It checks the whole headset in one place.
Most often the plug isn't fully seated in the jack, which can drop a channel or the mic on a combo connector. Push it in firmly. Also check the system balance isn't shifted to one side and, for USB headsets, that the headset is the selected output device.
Make sure the headset is selected as the input device (USB headsets can default to output only), check for a mute switch on the cable or earcup, and confirm you allowed microphone access. If the level meter stays flat when you speak, the browser is likely listening to a different microphone.
No. The tones are generated locally and your microphone audio is analysed on your device only. Nothing is recorded to a server or uploaded, and any clip you record stays in your browser and is discarded when you record again or leave the page.
Yes. Any headset your system recognises works, whether it's a 3.5 mm, USB or Bluetooth model. Just make sure it's set as both the output and input device so the earpiece and microphone tests both use the headset.
