Speaker & Headphone Test

How to use

1. Set a comfortable volume. Drag the Volume slider down before the first tone, then bring it up to a normal listening level. The tone is steady, so you don't need it loud.
2. Play one side at a time. Click L. The tone should come only from your left speaker or left earcup. Click R and check that it jumps to the right.
3. Play both channels. Hit Both channels for a centered tone. If one side sounds louder, your balance or a driver is off.

Why test this

Stereo faults are easy to miss. A channel can quit, a cheap adapter can cross left and right, or an OS balance slider can creep to one side. Music and video hide all of it, because your brain fills in whatever is missing. It only bites when direction matters. In a game, a footstep to your left should sound left. In a mix, a swapped channel ruins the result. And if you've just opened new headphones, you want to catch the problem before the return window closes. Feeding a clean tone to one channel at a time is the surest way to confirm each side works and sits where it should. It also pins the blame correctly. If the left tone plays left here but your game sounds reversed, the problem is in the game or the OS, not the headphones.

What the results mean

Press L and the tone should sit fully on the left. Press R and it should jump fully to the right. Each side should come through clean, with nothing bleeding across. Both channels should land dead center and match in volume. If the left tone comes out on the right, your channels are crossed: check the headphones aren't reversed, then the cable, the adapter, and any flipped setting. If one side is weak or silent, recenter the OS balance slider and test again, because a mis-set balance looks exactly like a dead speaker. When a side stays dead across cables, ports, and devices, the driver or its wiring is gone. A tone that buzzes or crackles points to a loose connection or a failing driver, not a routing problem.

FAQ

How do I know my headphones are on the right way round?

Play the left channel. The tone should come from the earcup on your left. If it shows up on your right, the headphones are turned around or the channels are swapped somewhere in software.

The left tone comes out of my right ear. What causes that?

Swapped channels. Either the headphones are reversed, a cable or adapter crosses the wires, or a balance or mono setting is flipped in your OS. Re-seat the headphones first, then work back through the cable and your sound settings.

Only one side plays. Is the speaker dead?

Not always. Check the OS balance slider first, since a setting pushed to one side mimics a dead speaker exactly. Then try a different cable, port, and device. If the same side stays silent everywhere, the driver or its wiring has failed.

Will this test a 5.1 or 7.1 surround headset?

It tests the two stereo channels those headsets play through. Most "7.1" gaming headsets are virtual surround over a single stereo pair, so this still checks the real drivers. A true 5.1 speaker set has center, rear, and sub channels you route in your OS, not here.

Is it safe for my hearing and my speakers?

Yes, at a sensible level. The tone is a steady 440 Hz sine at the volume you pick. Keep the slider moderate. Long blasts at high volume tire your ears and push small drivers harder than they like.
