Short answer: the Simgot ET142. Both are rated 3.8/5 for sound quality (#573 and #604 of 1291 in-ear headphones), and the Simgot ET142 costs $249.99 against $259 for the TANGZU Zetian Wu Legend, with sound quality a draw, the lower price decides it.
What the Simgot ET142 does well: The median of 17 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.07 dB spread. Watch for: A 7.9 dB peak near 7.9 kHz can make cymbals and sibilance sound sharp.
Why pick the TANGZU Zetian Wu Legend: A dual planar IEM with a 14.2mm bass planar and a 6mm treble planar. The catch: Treble sits about 2.5 dB below target, a dark, relaxed balance.
Buy the Simgot ET142. Both are rated the same for sound quality, and it costs $9.01 less than the TANGZU Zetian Wu Legend.

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.
