Short answer: the TANGZU Wu Legend. It ranks #518 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $259; the Kiwi Ears Halcyon ranks #576, rated 3.8/5, at $259. With prices this close, go by the sound-quality ranking rather than the cost.
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 Kiwi Ears Halcyon: The median of 16 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.07 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 3.4 dB low with a 6.5 dB dip near 6.1 kHz, so vocals and instruments lose some bite.
Buy the TANGZU Wu Legend. It is rated higher for sound quality than the Kiwi Ears Halcyon at the same price, which makes it the one to get unless you need something the other one 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.
