Short answer: the Arisyn Huo Shu. Both are rated 3.7/5 for sound quality (#668 and #634 of 1291 in-ear headphones), and the Arisyn Huo Shu costs $49.99 against $54.99 for the KZ ZS10 Pro 2, and with sound quality even, the cheaper one is the better buy.
The case for the Arisyn Huo Shu: A budget single dynamic IEM with a 10mm LCP driver and a wood faceplate. The catch: Treble sits about 2.8 dB below target, a dark, relaxed balance.
What the KZ ZS10 Pro 2 does well: The median of 9 hobbyist measurements gives it a solid Harman preference score of 70 with a 2.13 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The tradeoff: An 8 dB peak near 10.9 kHz can make cymbals and sibilance sound sharp.
Buy the Arisyn Huo Shu. Both are rated the same for sound quality, and it costs $5 less than the KZ ZS10 Pro 2.

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.
