Headphone Checker: Left/Right

Is one of your earbuds silent, quiet, or acting up? Headphone Checker helps you quickly test the left and right channels to find out.

How it works

Tap left or right on screen, and the app plays a sound through only that channel. No sound on one side means you’ve found the faulty earbud.

Two ways to test:
- Voice mode — hear a spoken “left” or “right”
- Melody mode — hear a short musical cue

Features

- Independent left and right channel testing
- Voice or melody test sounds
- Light and dark theme
- Bluetooth connection status at a glance
- Clean, fast interface — nothing to configure
