Look closer. Listen for yourself.

Compare responses.

Measured shapes, side by side. Add up to six curves; a curve is not a verdict.

Selected curves

0 / 6

Add a product to begin. Its default measurements form a consensus within its main rig partition.

Level alignment & spread

Curves are aligned to the first using the response-distance weighted least-squares offset across 20 Hz–20 kHz, with balanced focus and conservative reliability weights. Smoothing is display-only. Shading is the observed default-measurement min/max when at least two sources contribute, not a confidence interval. Missing overlap is not extrapolated.

Comparison workspace

Frequency-response curves show relative level across frequency, not how a product will sound in your ear. 0 curves. Missing measurements remain gaps. No measurements selected.

Level (dB)

Add a product or upload a measurement to inspect its response.

Frequency (Hz)
Sources and limitations
A measurement is not an ear. Fit, seal and insertion depth matter; response above 8 kHz is less reliable.
