Short answer: the Unique Melody 3DT. It ranks #106 of 450 in-ear headphones by sound quality, rated 4.4/5, at $399; the ThieAudio Hype 2 ranks #161, rated 4.3/5, at $399. The price gap is small enough that the sound-quality ranking should decide it.
The case for the Unique Melody 3DT: 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. Watch for: A 7 dB peak near 8 kHz adds an edge to cymbals and sibilance that some listeners will find fatiguing.
Buy the Unique Melody 3DT. It is rated higher for sound quality than the ThieAudio Hype 2 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

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.
