Short answer: the DITA Mecha. It ranks #382 of 1291 in-ear headphones by sound quality, rated 4.0/5, at $899; the Unique Melody MEXT ranks #507, rated 3.9/5, and costs $999, so there is little reason to consider the other one.
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.
The case for the Unique Melody MEXT: Bass is full and well extended, sitting about 1 dB above target from 20 Hz to 200 Hz in squig.link measurements, which gives electronic music and film scores solid low end weight. Watch for: Across hobbyist measurements the presence region sits 4.5 dB low with a 7.6 dB dip near 3.5 kHz, so vocals and guitars can sound recessed and lack bite.
Buy the DITA Mecha. It is rated higher for sound quality than the Unique Melody MEXT and costs less, which makes it the one to get unless you need something the other one does better.

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.
