How does the online test work?
You just need to press the appropriate buttons:
- The “Left” button will hear the test signal only in your left ear. Check the volume and clarity of the sound.
- The “Right” button will play the signal in the right channel. Check for crackling or popping.
- The “Both” button will play the same signal in both earbuds.
Why test your headphones?
Over time, headphones can develop problems: a kinked cable, a clogged mesh, oxidized contacts, or a system settings issue. Channel balance is most often affected, causing the left or right speaker to sound quieter, distorted, or not working at all. This test will immediately reveal the problem.
What problems can this test identify?
- Channel imbalance (one earbud is louder than the other).
- Complete failure of the left or right speaker.
- Sound distortion, crackling, or popping in a specific channel.
- Problems with the connection or cable (if the sound disappears when moving).
- Incorrect audio system settings in Windows, macOS, Android, or iOS.
What should I do after the test?
- If the test was perfect, your headphones are fine! The problem may be with the sound source (for example, a mono file).
- If one channel (Left or Right) isn’t working: check the cable for kinks and try connecting the headphones to a different device. There may be a physical defect.
- If the sound is offset: adjust the channel balance in your operating system’s sound settings.
