#134 EarAcoustic Genesis Mix9: $420 eBay
Pros: A nine driver hybrid with a dynamic woofer, four balanced armatures and four planar drivers, scoring 80. Bass reaches 20 Hz and the midrange stays within about 1.5 dB of target.
Cons: Presence and treble run 1 to 2 dB low with dips of 5.7 dB near 4 kHz and 5.2 dB near 6.1 kHz, so it can sound a bit polite. It sells mainly in Japan and Europe at about $420, and the score rests on a single measurement.

Frequency Response
How the EarAcoustic Genesis Mix9 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 aftersound. Thanks to them for publishing their work.
