Short answer: the Xenns Mangird Tea Pro. Both are rated 4.0/5 for sound quality (#384 and #459 of 1291 in-ear headphones), and the Xenns Mangird Tea Pro costs $359 against $379 for the Plunge Audio Unity Dynamic, so with nothing between them on sound quality, price settles it.
What the Plunge Audio Unity Dynamic does well: A broadly balanced tuning with a preference score of 73 against the Harman target. The catch: An uneven response, 2.2 dB standard deviation from target.
Why pick the Xenns Mangird Tea Pro: The median of 14 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.74 dB spread. Watch for: Presence sits about 4.3 dB low with a 6 dB dip near 5.8 kHz, so vocals and instruments lose some bite.
Buy the Xenns Mangird Tea Pro. Both are rated the same for sound quality, and it costs $20 less than the Plunge Audio Unity Dynamic.

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.
