Test Channel Balance
Use the Left, Right and Both buttons. A healthy pair plays equal volume on each side, with the tone in the center when both play.
Test Different Frequencies
Tap the frequency chips: 200 Hz for bass, 1 kHz for mids and 3 kHz for presence. Tones should be clean and steady. Fuzziness suggests damage or dirt. Compare against a second pair if unsure.
Fix Common Headphone Issues
Clean the mesh gently with a dry brush, reconnect Bluetooth, update firmware and check for the correct output device. For microphone problems see microphone test.
Protect Your Hearing
Keep volume at a comfortable level and take breaks. The World Health Organization provides guidance on safe listening. Also check hearing range test.
