#214 Harmonic Empire Xiao Qiao: $69.00 Amazon $69.00 eBay
Pros: A semi-open single dynamic IEM that measures very close to the Harman target (score 77 across seven measurements), with bass and treble each within 1.4 dB of it.
Cons: The semi-open design leaks sound and isolates less than sealed IEMs, so it is a poor choice for commuting or noisy places.

Frequency Response
How the Harmonic Empire Xiao Qiao 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 7 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 7 measurements from the squig.link databases of aden, aftersound, audioamigo, bassaudio, csi-zone, soundcheck39 and soundignity. Thanks to each of them for publishing their work.
