Short answer: the HiBy Yacht10. It ranks #595 of 1291 in-ear headphones by sound quality, rated 3.8/5, at $129; the Kiwi Ears Airoso ranks #636, rated 3.7/5, at $129. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick 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 Airoso: A warm, even tuning measured by 23 people with a 2.0 dB spread: bass sits about 2.6 dB above target with clean extension, mids stay close to neutral, and upper air lifts about 3 dB. The catch: Presence dips about 3.5 dB with a 6.6 dB low point near 5.6 kHz, softening vocal edge, and a 3.9 dB peak near 12 kHz adds some brightness.
Buy the HiBy Yacht10. It is rated higher for sound quality than the Kiwi Ears Airoso 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.
