Headphones test

Make sure left and right sound right.

Ready to test

Check both ears

Set a comfortable volume, then listen to each channel. Audio plays only after you press a button.

You should hear a short tone on the side you choose. If left and right sound swapped, check your headset connection and system audio settings.

How to check your headphones

Choose a comfortable system volume first. This test plays a brief tone after you press a channel button; it cannot change your computer's output device.

Select your output

Connect your headphones and choose them in your computer's sound output settings.

Try each channel

Press Left, Right, and Both. Listen for the tone in the expected ear or speaker.

Fix missing sound

Check volume, connection, and output selection. If the sides are reversed, inspect your headset or system audio settings.

If a test doesn't work

Headphones have no sound

Raise the system volume to a comfortable level and choose the correct output device in your computer's sound settings. Try Left and Right separately to catch swapped channels.

Camera shows no picture

Check the camera selected above and the browser's camera permission. Close other apps using the camera, then restart the test. Your video remains in this browser.

Your tests stay with you. Microphone audio and camera video are processed in your browser. A short microphone recording is kept only in this open browser session so you can play it back; it is removed when you leave the page. We do not upload or save recordings, video, device names, or detailed test readings.
