How to test
- Lower your volume, open Headphone Test and confirm the volume warning.
- Play left, right and both channels. Each side should sound only on its own earcup.
- Try the stereo, frequency, bass, noise and balance tests.
- Open Microphone Test, press Start, allow access, then speak and watch the level meter.
- Record in Recording Studio, play it back and download it.
- Run the noise and speech checks in Audio Diagnostics.
Privacy
Your microphone audio stays on your device. GearBlizz does not upload, store or transmit your recordings.
The microphone only turns on when you press a button, and it is released when you stop or leave the microphone sections.
Headphone test
Start at low volume. High-frequency and loud sounds can damage hearing.
Left / right channel
A 440 Hz tone on one side at a time. Tap an active button again to stop.
Stereo test
Alternating sound switches sides every 0.8 s. The sweep glides smoothly from left to right.
Frequency generator
Sine wave through both channels.
Bass test
Many headphones roll off below 40 Hz, so quiet or absent tones at the lowest steps are common.
Audio quality
Noise and test waveforms for checking distortion, rattle and tonal balance. Waveforms play at 440 Hz.
Stereo balance
Play a sound, then move the slider until it feels centered. A centered slider means equal level in both ears; a large offset can point to a driver mismatch, a poor seal or an uneven ear.
Volume is relative to your system volume. Keep it low and raise it gradually.

Record & listen back
The best way to judge quality is to hear it. Record a few seconds of your voice, then play it back through your headphones or speakers. Listen for hiss, crackle, distortion and a muffled sound.
Input level
Levels are digital dBFS, where 0 dBFS is the loudest value the browser can record. They are approximate and are not sound pressure (dB SPL). Activity lights above −50 dBFS. Average covers the time since you started or reset.

Record & play back
Voice test
Press start, then read the sentence aloud at a normal volume. The test records for 10 seconds, then you can play it back and download the audio and a report of the measured levels.

Guided checks
Each check listens through the selected microphone and reports what it measured. Results are approximate and describe this microphone, room and gain setting, not the microphone's frequency response.
Pick a check to begin.
Recording playback check: record a clip in the Recording Studio and listen for crackle, dropouts or hiss.
Live checks
Start the microphone to run these continuously. Silence and weak-signal checks refresh every 3 seconds.
- Clipping: Not running
- Silence (below −80 dBFS): Not running
- Weak signal (peak below −30 dBFS): Not running
