Frequency Response
How the Penon Fan 3 measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the median of 10 independent measurements, so one odd sample or rig cannot skew it, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: median of 10 measurements from the squig.link databases of aden, dl, flare, isaiahse, jaytiss, koi, sl0the, superreview, theaudiostore and treblewellxtended. Thanks to each of them for publishing their work.
