Short answer: the HIFIMAN RE2000. It ranks #685 of 1369 in-ear headphones by sound quality, rated 3.6/5, at $799; the Unique Melody Maven II ranks #908, rated 3.4/5, and costs $1,799, so there is little reason to consider the other one.
The case for the HIFIMAN RE2000: Crinacle’s measurement gives a Harman preference score of 69 with a deviation of 2.63 dB, a respectable match to the target most listeners prefer. The catch: A score of 69 is only middling for a flagship in-ear, and a response that deviates from the target by 2.63 dB leaves audible coloration.
Why pick the Unique Melody Maven II: A broadly balanced tuning with a preference score of 66 against the Harman target. Watch for: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the HIFIMAN RE2000. It is rated higher for sound quality than the Unique Melody Maven II and costs less, so only choose the other one for a particular feature it does better.
