Short answer: the DUNU DN142. Both are rated 3.8/5 for sound quality (#544 and #604 of 1291 in-ear headphones), and the DUNU DN142 costs $249.99 against $259 for the TANGZU Zetian Wu Legend, with sound quality a draw, the lower price decides it.
Why pick the DUNU DN142: The median of 11 hobbyist measurements gives it a solid Harman preference score of 72 with a 1.89 dB spread, and its mids sit within about 1 dB of target, so vocals and instruments sound natural. The tradeoff: Presence sits about 3.4 dB low with a 6.4 dB dip near 6.7 kHz, so vocals and instruments lose some bite.
What the TANGZU Zetian Wu Legend does well: A dual planar IEM with a 14.2mm bass planar and a 6mm treble planar. Watch for: Treble sits about 2.5 dB below target, a dark, relaxed balance.

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.
