Short answer: the TANGZU Wu Legend. It ranks #518 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $259; the TANGZU Zetian Wu Legend ranks #604, rated 3.8/5, at $259. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the TANGZU Wu Legend: Dual planar magnetic drivers (14.2 mm and 6 mm) give the Wu Legend a warm, bass-leaning tuning with bass and midrange within a decibel of target in squig.link hobbyist measurements. Watch for: A 6.3 dB dip near 3.75 kHz pulls the presence region about 5 dB under target, so vocals and guitars sound distant, while air jumps about 8 dB above target with a 7.4 dB peak near 10.9 kHz that can make treble sound glassy.
Why pick the TANGZU Zetian Wu Legend: 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.
Buy the TANGZU Wu Legend. It is rated higher for sound quality than the TANGZU Zetian Wu Legend at the same price, so only choose the other one for a particular feature it does better.

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.
