This page gives you a short general-purpose headphone check that covers the most common questions first: do both channels work, does the stereo image center correctly, is bass present, and can the drivers still reproduce a gentle high tone without obvious problems? It is useful for new headphones, recently repaired devices, Bluetooth earbuds after pairing, or any setup that suddenly sounds wrong. The test does not autoplay. You trigger each step yourself and can stop the sound at any time.
Play a short tone that should appear only in the left ear cup. If it sounds centered, channel routing may be wrong.
If left and right both play in the correct ear, your basic channel routing is probably fine. A centered stereo tone usually means the channel balance is close enough for everyday listening. If bass is missing, the cause may be weak driver output, a poor seal with earbuds, or device EQ settings. If the high tone is missing, keep in mind that some listeners, especially adults, naturally hear less at the top of the range.
This is a convenience tool, not a stress test. There is no benefit in running it loudly. Low listening levels are enough to confirm channel routing, bass presence and basic treble output. If a tone sounds uncomfortable, stop immediately and lower the volume before continuing.
Use this page as a first pass. It walks through the most important checks before you move to a more specific tool.
Check system audio settings, adapter wiring and Bluetooth balance settings, then confirm the result again with the Left / Right Audio Test.
Very low tones are naturally harder to reproduce and easier to lose with a poor earbud seal. Try the Bass Test for more detail.
Yes. The quick check still works for speakers, although room acoustics may affect the bass and stereo impression.
