Short answer: the ZiiGaat Arcanis. It ranks #781 of 1291 in-ear headphones by sound quality, rated 3.5/5, at $399; the Tangzu Nezha ranks #884, rated 3.4/5, at $399. Close enough in price that the sound-quality gap is the deciding factor.
The case for the ZiiGaat Arcanis: Mids from 250 Hz to 3 kHz sit within 1 dB of target across 25 measurements, so vocals and acoustic instruments sound natural. Watch for: Presence falls about 7 dB low with a 9.8 dB dip near 5.9 kHz, which strips detail and edge from instruments, and sub-bass is 2.1 dB short at 30 Hz.
Why pick the Tangzu Nezha: A broadly balanced tuning with a preference score of 66 against the Harman target. Watch for: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the ZiiGaat Arcanis. It is rated higher for sound quality than the Tangzu Nezha at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

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.
