Short answer: the CCA C12. It ranks #561 of 1291 in-ear headphones by sound quality, rated 3.8/5, at $42.05; the Arisyn Huo Shu ranks #668, rated 3.7/5, and costs $49.99, which makes this an easy call rather than a real tradeoff.
Why pick the CCA C12: Sub-bass sits within 0.2 dB of target and holds up all the way to 20 Hz across hobbyist measurements on squig.link, and a 3.3 dB lift from 60 to 200 Hz adds warm punch to drums and bass lines. The tradeoff: The top octave runs 7.5 dB above target with an 8.8 dB peak near 11.9 kHz, which can add sizzle to cymbals and hiss to bright recordings.
What the Arisyn Huo Shu does well: A budget single dynamic IEM with a 10mm LCP driver and a wood faceplate. Watch for: Treble sits about 2.8 dB below target, a dark, relaxed balance.
Buy the CCA C12. It is rated higher for sound quality than the Arisyn Huo Shu and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
Measurement data: the CCA C12 from avishai, isaiahse and melatonin; the Arisyn Huo Shu from aftersound, bassaudio, digaoreviews, fernandagunsan, jaytiss, pw, soundcheck39 and soundignity, all via squig.link.
