#100 Tangzu x HBB Wu Zetian: $199 Discontinued eBay
Pros: A 14.5 mm planar IEM with a preference score of 81. Bass and midrange stay within about 1 dB of target to 20 Hz, and the cable comes with swappable 2.5, 3.5 and 4.4 mm plugs.
Cons: Presence and treble run about 2 dB low with dips of 4.5 dB near 4.1 kHz and 4 dB near 10.3 kHz, so it sounds a little relaxed. It is discontinued after selling for $199, and the score rests on a single measurement.

Frequency Response
How the Tangzu x HBB Wu Zetian 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 a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of nymz. Thanks to them for publishing their work.
