Short answer: the HIFIMAN Svanar. It ranks #834 of 1369 in-ear headphones by sound quality, rated 3.5/5, at $1,999. The Unique Melody MEST MKIII ranks #903, rated 3.4/5, at $1,919, $80 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the HIFIMAN Svanar: A single dynamic flagship using HIFIMAN’s Topology Diaphragm. Watch for: Bass sits about 2.5 dB above target, a bass heavy balance.
Why pick the Unique Melody MEST MKIII: A broadly balanced tuning with a preference score of 66 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the HIFIMAN Svanar. It is rated higher for sound quality, and the $80 saving on the Unique Melody MEST MKIII 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.
