- Reviews, Comparisons and Sound Samples
Frequency Response
How the CVJ Kira 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.
Measurement data: median of 3 measurements from the squig.link databases of eplv, kuping-sensi and soundignity. Thanks to each of them for publishing their work.
