Short answer: the Moondrop x Crinacle Dusk. It ranks #109 of 1291 in-ear headphones by sound quality, rated 4.5/5, at $399.99; the Unique Melody 3DT ranks #139, rated 4.4/5, at $399. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the Moondrop x Crinacle Dusk: The median of 28 hobbyist measurements gives it an excellent Harman preference score of 80 with a 1.36 dB spread, and its mids sit within about 1.2 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 3.6 dB low with a 4.7 dB dip near 6.7 kHz, so vocals and instruments lose some bite.
What the Unique Melody 3DT does well: Four hobbyist measurements on squig.link give the 3DT a preference score of 79.0, with its three dynamic drivers producing a balanced response where every band from 60 Hz to 10 kHz sits within 1.6 dB of target. The catch: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing.
Buy the Moondrop x Crinacle Dusk. It is rated higher for sound quality, and the $0.99 saving on the Unique Melody 3DT is not enough to make up the difference.

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.
