Headphone Test
Test your headphones for left ear, right ear, and stereo audio. Verify both drivers are working.
Wear headphones and click each button to verify both ears are working and channels are correct.
How does this test work?
A headphone test plays tones through the left ear, right ear, and both ears so you can verify both headphone drivers work and the channels are correct.

Frequently Asked Questions
One ear of my headphones is not working. Is it broken?+
If one ear produces no sound during the test, the driver in that ear may be damaged, or the cable/connector has a loose connection. Try wiggling the plug to check for a loose connection.
