Fast answer: Use this guide as a practical checklist for headphone and speaker test: check left and right audio channels. Start with the main browser tool, confirm the result with one focused follow-up test, then change only one device, browser, or setting at a time so you know what actually fixed the issue.
Are both your headphone drivers working? Is the left and right audio properly balanced? A simple stereo test can answer these questions in seconds. This is essential before recording, mixing, or even just watching movies.
How to Test Your Headphones
- Open the headphone/speaker tester
- Put on your headphones
- Play the left channel test — you should only hear sound in your left ear
- Play the right channel test — you should only hear sound in your right ear
- If both ears hear both channels, your wiring may be incorrect
Common Audio Issues
- One channel not working: Likely a damaged driver or broken cable
- Channels swapped: Left and right are reversed — check your headphone orientation or audio settings
- Crackling/static: Loose connection, damaged cable, or interference
- Volume imbalance: One side is louder — adjust balance in your OS audio settings

FAQ
Do I need to install anything for this guide?
No. The recommended checks run in a modern browser unless the article specifically points you to an operating-system or device setting.
Is the browser test private?
The KeyboardTester.click tools are designed to run the test interaction in your browser. Do not type passwords, private messages, or sensitive account data into any testing page.
What should I do if the result looks wrong?
Repeat the test in a clean browser tab, then change one variable at a time such as device, cable, USB port, permission, wireless mode, or browser profile.
When should I use a related tool?
Use a related tool when the first result points to a narrower issue, such as latency, ghosting, stuck input, camera permission, audio routing, or QR/OCR decoding quality.
