This is a free stereo channel test tool. Test your left/right speakers, headphones, or soundbar. Uses the Web Audio API โ works offline as a PWA. All audio is generated locally in your browser.
Verify your new headphones work perfectly out of the box. Check driver matching, stereo imaging, and overall sound quality before the return window closes.
Is one side quieter? Is there distortion? Identify whether the problem is in the headphones, cable, or audio source before spending money on repairs.
Ensure your studio headphones have perfectly matched drivers for accurate mixing. Even 1-2dB channel imbalance can skew your stereo image decisions.
Test stereo imaging for competitive gaming. Accurate left/right positioning can be the difference between winning and losing in FPS games.
Test each wireless earbud independently. Bluetooth connection issues can cause one side to be quieter or delayed โ our test helps you spot these problems.
Some audiophiles believe headphones 'burn in' after hours of use. Test before and after burn-in to check if the sound actually changed.
