Check channels, center image, phase, bass, and range.
Use defined low-level signals to identify routing, balance, polarity, and obvious playback problems without downloading an audio file.
Headphone channel and range bench
Remove headphones first if your current volume is unknown. MeterSee limits its generated level, but the operating system, amplifier, and headphones determine actual sound pressure.
Ready for a controlled listening test
Play one signal at a time and confirm the result after it stops. A signal is never counted as passed merely because its button was clicked.
The Web Audio graph produces defined stereo and frequency signals. MeterSee cannot hear the transducers, measure sound pressure, or certify frequency response. Hearing sensitivity varies; do not increase volume to chase inaudible high or low frequencies.
Treat listening results as functional evidence.
The browser can generate defined signals but cannot measure the acoustic output of physical headphones without calibrated capture hardware.
Verify operating-system balance, reseat the connector, and compare another output device.
Reverse the headphones physically and compare whether the direction follows the hardware or the listener.
Lower volume, reseat the headphones, and compare a second pair. Do not increase volume to chase inaudible frequencies.
Headphone listening checks
How this test works
Channel, center, polarity, bass, and sweep signals help you compare what you hear. The generated frequency is known; the physical sound level is not.
What this cannot establish
This is not an audiogram, frequency-response measurement, or Bluetooth latency meter. Do not turn up the volume to hear an inaudible frequency. Compare a second pair at a comfortable level.
Recheck before replacing hardware
Change one variable at a time, repeat under the same conditions, and compare with the operating system or the affected application. An unavailable reading is not a pass.
Relevant fix guides
- One headphone side is quieter: separate channel settings from the physical listening pathUneven headphone sound can begin with a balance setting, the source audio, an imperfect connection, earbud fit, or the device itself. A low-volume comparison can narrow the problem without forcing the quiet side louder.
- Bluetooth audio delay: find which part of the listening path is lateA late sound can come from Bluetooth buffering, a video player's synchronization, a game's processing, or the return path of a call. A controlled comparison is more useful than a universal latency fix.
