Short answer: the Kiwi Ears Etude. Both are rated 3.8/5 for sound quality (#574 and #595 of 1291 in-ear headphones), and the Kiwi Ears Etude costs $119 against $129 for the HiBy Yacht10, and with sound quality even, the cheaper one is the better buy.
The case for the HiBy Yacht10: A single dynamic IEM with a 10mm magnesium aluminum dome. The catch: A 2.31 dB spread from the target shows peaks and dips that better tuned sets avoid.
Why pick the Kiwi Ears Etude: The median of 17 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.05 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.7 dB low with a 5.8 dB dip near 4.0 kHz, so vocals and instruments lose some bite.
Buy the Kiwi Ears Etude. Both are rated the same for sound quality, and it costs $10 less than the HiBy Yacht10.

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.
