Follow these simple steps to test your headphones
Connect your headphones or earbuds to your device via 3.5mm jack, USB, or Bluetooth. Ensure they are properly connected.
Set the volume to a comfortable level. Start with low volume and gradually increase to avoid hearing damage.
Use channel test, frequency sweep, and music playback to evaluate your headphone performance across different aspects.
Check the oscilloscope display and test results to identify any issues with your headphones' audio quality.

Common questions about headphone testing
Possible reasons include: 1) Headphones not properly connected; 2) System volume muted or too low; 3) Wrong audio output device selected in system settings. Check your connections and audio settings.
This usually indicates a wiring issue or driver imbalance. Try: 1) Check the headphone cable connection; 2) Clean the audio jack; 3) Test with different audio source; 4) Use the balance control to compensate temporarily.
The frequency sweep test plays tones from 20Hz to 20kHz. If you can't hear certain frequencies: 1) Low frequencies (20-100Hz) require headphones with good bass response; 2) High frequencies (15kHz+) may be inaudible due to age-related hearing loss; 3) Some budget headphones have limited frequency range.
For accurate testing: 1) Use a quiet environment; 2) Start with low volume and increase gradually; 3) Test each channel separately first; 4) Compare results with known good headphones; 5) Run multiple tests for consistency.
Yes! High volume levels can cause permanent hearing damage. Always: 1) Start with low volume; 2) Take breaks during extended testing; 3) Avoid prolonged exposure to high frequencies; 4) If you experience discomfort, stop immediately.
The oscilloscope shows real-time audio waveforms. A clean sine wave indicates pure tone playback. Distorted or clipped waveforms may indicate: 1) Volume too high; 2) Driver distortion; 3) Poor quality audio source. Use it to visually verify audio quality.
