Reviews, Comparisons and Sound Samples
- Frequency response measurements of the BLON Shu by 3 squig.link measurers

Frequency Response

How the BLON Shu 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 3 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.
