Listen to what this product sounds like Estimated: Warm

Estimated tuning - how it was calculated: From a pair of earphones - the curve is that family's typical response, not a lab measurement of this exact unit.

Estimated bands vs the mids anchor (300–1000 Hz mean): bass +3.1 dB Β· treble +1.9 dB - the size of the deviation from flat this preview plays.

Same signal, two ways: Without this is baseline flatness (no EQ at all - the reference line at 0 dB), With this plays this product's estimated tuning curve through the EQ - flip live and hear what the tuning family adds to, and takes from, a flat source.

Wearing your own earphones or headphones? Pick them here and the player pre-corrects for their sound, so the demo plays the target tuning itself - not both mixed together.

Take the tuning with you - the same estimated curve ships as an EQ preset: Equalizer APO (.txt) GraphicEQ Qudelix-5K / Wavelet (CSV) Preset page

Tuning tools

EQ presets - Equalizer APO, Qudelix-5K, Wavelet

Generated from this product's labeled estimate curve - its tuning family, not a lab measurement - toward an approximate Harman in-ear (IE 2019) target. When a measurement lands, the preset regenerates from it automatically. An estimate - a starting point for people who already EQ, not a verdict. The same ten filters load into each tool: Equalizer APO runs them system-wide on Windows, the Qudelix-5K / 71 app takes the CSV as a paste-in import, Wavelet (Android) imports the same CSV into its parametric EQ.

Compatibility checker

No specs on file from any synced store listing yet - and this page never guesses. The rules below still apply to what you own; the listing photos usually settle the connector and plug.

How to read the specs off a listing (photos usually settle it)

  • Connector: 2-pin is two flat pins leaving the shell; MMCX is a round, coaxial click-in stud.
  • Plug size: the jack on the cable's source end - 3.5mm plain, 4.4mm/2.5mm balanced, or a fixed USB-C/Lightning wire.
  • Impedance and sensitivity: usually in the listing's spec table. Sensitivity may be quoted per mW or per V - the unit picker above flips the math.
