A headphone test checks whether both channels play clearly and whether their balance feels consistent. Start with the panning control, compare the center position, then try spatial audio or the wireless sync flash. The result depends on headphone fit, device settings, and the listener; it is not a laboratory quality score.
Start with your device volume low. 50% here does not guarantee a safe listening level.

A SIMPLE START
How to run this audio check
01
Fit and connect your headphones
Wear the marked left and right sides correctly. Seat earbuds comfortably, choose the intended output, and lower the device volume.
02
Move the balance across the range
Play the balance signal and move from left to center to right. Listen for a silent side, abrupt dropouts, or an unexpected shift at center.
03
Check spatial sound and sync separately
Run the short binaural orbit, then the five-beep sync check. Stop between tests and compare a wired connection if wireless delay is noticeable.
Check headphones, earphones, and gaming headsets
A headset combines an output device with a microphone, so a successful headphone audio check does not confirm the input works. First compare the two earpieces using the same signal. Then use the microphone page if callers cannot hear you. Your operating system or meeting app may list the input and output under different names.
For earbuds, fit can change the low-frequency impression substantially. Reseat both sides before adjusting balance to compensate. Compare the same pair with another source at a similarly comfortable level. A repeatable difference is more useful than a single impression from a song with uneven mixing.
Understanding the binaural spatial check
The spatial button moves a synthetic source around a listener model using HRTF processing. The changing cues can help you explore front, side, and rear impressions on headphones. They do not certify a headset’s advertised surround mode, and the apparent direction can vary from one listener to another.
For a reference comparison, note whether other spatial processing is already enabled on the device. Applying another virtual-surround effect can change the browser’s result. Compare one configuration at a time and return to the balance signal if the spatial impression makes basic channel orientation unclear.
Wireless delay: what the flash can reveal
The sync test pairs a visible flash with a short beep. A repeatable late beep can suggest playback delay, especially when it changes between wired and wireless output. The display, browser scheduling, and device buffering also contribute, so this comparison cannot report an exact end-to-end Bluetooth latency number.
The engine latency figure shown after audio starts is only the browser’s reported estimate. It does not include every wireless or hardware delay. Use the visual check to compare your own setups under similar conditions rather than to rank unrelated products by a supposedly precise measurement.

How do I test the sound quality of headphones online?+
Begin with low-volume left/right balance, then listen for dropouts, buzzing, and inconsistent level. Use a short tone sweep for frequency-specific problems and familiar audio for everyday listening. Browser tools help reveal symptoms but cannot produce a calibrated quality rating or separate headphone response from fit and hearing differences.
Can I use this test for wireless earbuds?+
Yes. Pair both earbuds and select them as the browser’s output, then compare the left and right channels. Check fit and charge if one side seems weak. The sync flash offers a visual delay comparison, but it does not measure the complete Bluetooth path in exact milliseconds.
Why does my headset sound different during a call?+
A call can use a different output device, communication mode, gain setting, or processing path from normal playback. Compare the selected devices inside the meeting app with your system settings. A browser test is a useful reference, but repeat the check in the application where the problem occurs.
Does the binaural test prove my headphones support 7.1?+
No. It creates spatial cues for ordinary two-channel headphone playback. A convincing impression does not demonstrate eight independent hardware channels, and a weak impression does not prove the headphones are defective. Use it as a listening comparison; discrete 7.1 speaker testing requires a compatible multichannel output.
