Short answer: the Moondrop Blessing 3. Both are rated 4.4/5 for sound quality (#89 and #106 of 450 in-ear headphones), and the Moondrop Blessing 3 costs $359.99 against $399 for the Unique Melody 3DT, and with sound quality even, the cheaper one is the better buy.
The case for the Moondrop Blessing 3: Crinacle’s measurement gives it a preference score of 79, and the median of 38 hobbyist measurements on squig.link keeps every band from 20 Hz to 10 kHz within 2 dB of the Harman target, with a smooth 1.65 dB deviation. The tradeoff: The Etymotic EVO matches its rating for noticeably less money.
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 tradeoff: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing.
Buy the Moondrop Blessing 3. Both are rated the same for sound quality, and it costs $39.01 less than the Unique Melody 3DT.

Moondrop Blessing 3: $359.99 Amazon AliExpress eBay
Pros: Crinacle’s measurement gives it a preference score of 79, and the median of 38 hobbyist measurements on squig.link keeps every band from 20 Hz to 10 kHz within 2 dB of the Harman target, with a smooth 1.65 dB deviation. The result is balanced, natural sounding vocals and instruments with full bass extension. At 14.8 ohms and 120 dB/V it is easy to drive from a phone, and it rates above the Kiwi Ears Orchestra Lite and the FiiO FH5s.
Cons: The Etymotic EVO matches its rating for noticeably less money. A 3.8 dB dip near 6.9 kHz next to a 3.6 dB peak near 8.1 kHz gives the treble slight unevenness, and sub-bass sits about 2 dB under target, so it lacks the extra rumble bass lovers may want.

Unique Melody 3DT: $399.00 Linsoul eBay
Pros: 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. Midbass is gently lifted for warmth, and presence stays near neutral, so vocals sound clear and natural. At 113 dB sensitivity it runs easily from a phone.
Cons: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing. Sub-bass sits about 1.4 dB below target at 30 Hz, and it costs more than the equally rated Binary 1900 and Etymotic EVO.
