How to use this tool to test your equipment

• Latency Test: Click to hear a sound and feel the audio transmission delay.
• Simulated Surround Sound: Simulate sound moving around your head (8D Audio effect).
Unbalanced audio channels or one-sided sound are common headphone issues. This tool uses the browser's Web Audio API to generate test audio signals, automatically detecting your headphone connection status and outputting independent left and right channel test sounds. This helps users quickly verify if their headphone hardware is working correctly.
What should I do if the Bluetooth headphone test fails? Please ensure your Bluetooth headphones are set as the system's default audio output device. Some devices require you to manually switch the audio output channel in the system settings.
What audio formats does the testing tool support? This tool generates sine wave test tones via the Web Audio API, covering frequencies from 200Hz to 20kHz, and supports standard PCM audio output formats.
Before testing, make sure your device is not muted and your browser has granted microphone permissions. Loose physical connections or abnormal system audio drivers may cause false positives, so multiple tests are recommended. This tool does not collect user audio data, but always ensure you are on a secure network.
For audio professionals, we recommend using the 800Hz-1kHz test tone for baseline testing, as the human ear is most sensitive to this frequency range. Typical test scenario: Clicking "Play Left Channel" should produce a pure 800Hz tone on one side, and clicking "Spatial Audio Test" should reveal noticeable changes in stereo imaging. If the test results are normal but you still experience issues during actual use, please check the audio channel balance settings in your specific audio software.
