Fix settings when balance or mono routing is wrong.
Try another cable or adapter when the side changes by source.
Replace only when the same side stays quiet everywhere.
Repair picks
If one side stays quiet across devices and cables, a simple wired headphone replacement is the cleanest path.

FAQs
How do I test left and right headphone channels? +
Run the left/right audio test and listen for whether each side plays only when expected. Then check balance, mono audio, cable position, and another source before blaming the headphones.
Can one quiet headphone side be a settings problem? +
Yes. Balance, mono audio, app output routing, and loose connectors can make one side weak or silent even when the drivers are still working.
Should I replace headphones if one side is not working? +
Replace only when the same side stays quiet across sources, settings, and cables. If the fault moves with the cable or adapter, start there instead.
Repair path
If the same fault repeats, use the guide before buying replacement hardware.
Run the source test.
Use the matching live tester first, then return to the model page only if the fault repeats.
