Short answer: the DITA Mecha. It ranks #382 of 1291 in-ear headphones by sound quality, rated 4.0/5, at $899; the Meze Astru ranks #605, rated 3.8/5, at $899. Close enough in price that the sound-quality gap is the deciding factor.
The case for the DITA Mecha: Hobbyist measurements on squig.link put its preference score at 73.6 with a smooth 1.75 dB deviation, so no single band pulls far from a natural balance. The catch: A 4.7 dB dip near 6.3 kHz sits right beside a 5.2 dB peak near 8 kHz, so cymbals and sibilants can sound slightly uneven, recessed one moment and sharp the next.
What the Meze Astru does well: A single dynamic driver IEM with bass right on the Harman target and full sub-bass to 20 Hz. The catch: Expensive for its rating.
Buy the DITA Mecha. It is rated higher for sound quality than the Meze Astru at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
