Step by step
- Lower your system volume first, then put on your gaming headphones.
- Click Left and Right to confirm each sound plays only in that ear, ensuring footsteps and gunshots match on-screen direction.
- Click In phase and Out of phase: in-phase sound should feel centered, not wide or hollow.
- Run the 20 Hz–20 kHz sweep and 50 Hz bass test to check that low explosions do not rattle and mids/highs stay clear.

Related questions
Can I do an earphone test for gaming with this tool?
Yes. In-ear monitors and earbuds use the same left, right, and phase signals, so you can test channel separation and bass response the same way.
Why do footsteps sound like they come from the wrong side?
Your left and right channels may be swapped, or your headphones might be on backwards. Check the L and R markings first, then test Left and Right in the tool.
Does this test check my gaming headset microphone?
No, this tool only tests audio output (speakers and headphones). To check your mic, use your operating system sound input settings or your game's voice test.
