#380 Tago Studio x Moondrop Harmon-SP: $319 eBay
Pros: A three dynamic driver IEM with a preference score of 76. Bass is full to 20 Hz with a warm 2.7 dB upper bass lift, and the midrange stays within about 0.7 dB of target.
Cons: The treble is uneven, with a 5.2 dB peak near 8.2 kHz and dips near 6.1 kHz and 10.3 kHz. It is sold mainly in Japan at about $319, the 7.5 ohm impedance can reveal hiss, and the score rests on a single measurement.

Frequency Response
How the Tago Studio x Moondrop Harmon-SP 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 elrics. Thanks to them for publishing their work.
