#38 Sonicast Direm Pro II: $254.66 Amazon $254.66 eBay
Pros: A single dynamic driver earphone with a preference score of 83 and a low 1.24 dB deviation from target. Sub bass reaches fully to 20 Hz and every band from the lower mids to 12 kHz stays within 0.7 dB of target, so it sounds clean and natural.
Cons: Upper bass is about 1.6 dB above target and a 3.6 dB peak near 8.2 kHz adds slight edge. The cheaper Sonicast Direm E3 scores a little higher, and this score rests on a single measurement.
Is the Sonicast Direm Pro II right for you?
Buy it if

Frequency Response
How the Sonicast Direm Pro II 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 dl. Thanks to them for publishing their work.
