#638 Twistura D-Major Discontinued eBay
Pros: A single dynamic IEM with a beryllium plated driver and swappable nozzles. It measures reasonably close to the Harman target (score 68 across nine measurements).
Cons: Discontinued, so it is mainly found used. Bass sits about 2.0 dB below target, so it sounds lean. Sub-bass falls about 4.0 dB short at 30 Hz. A 2.31 dB spread from the target shows peaks and dips that better tuned sets avoid.

Frequency Response
How the Twistura D-Major 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 9 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 9 measurements from the squig.link databases of hu-fi, kuping-sensi, lumerion, musicafe, obodio, pw, soundignity, theaudiostore and treblewellxtended. Thanks to each of them for publishing their work.
