Headphone test

Headphone sequence

Headphone sequence

Check each earpiece separately, compare centered balance and finish with a short range sweep.

Run one reference at a time. Record what you actually hear before changing the setup.

  1. 01

    Left earpiece

    A 500 Hz tone should appear only in the left earpiece.

  2. 02

    Right earpiece

    The same 500 Hz tone should appear only in the right earpiece.

    Record this reference
  3. 03

    Centered balance

    Pink noise through both channels should appear centered rather than pulled to one side.

  4. 04

    Short headphone sweep

    A 200 Hz to 8 kHz sweep helps reveal a repeatable dropout or buzz.

    Record this reference

Check both sides with repeatable references and capture the result as evidence.

Interpretation: The test can reveal an audible imbalance or missing channel in the current complete path. Limit: One failed listening test cannot determine whether the headphones, cable, adapter, device or software caused it.

Safety and privacy: Start at a low device volume. No sound starts automatically. Use Stop all audio at any time. Signals and analysis stay in your browser by default. Browser dBFS is not physical SPL.

How to use this test

  1. 1.
    Wear the headphones normally: Confirm left and right orientation and keep operating-system balance centered.
  2. 2.
    Check each earpiece: Run the left and right references before comparing the centered signal and sweep.
  3. 3.
    Retest on another path: If a problem appears, repeat the same reference on a second device before assigning a cause.
