Short answer: the Rose Technics Ceramics. It ranks #558 of 1291 in-ear headphones by sound quality, rated 3.8/5, at $39.99. The CCA C10 ranks #630, rated 3.7/5, at $24.89, $15.10 cheaper, which does not close the gap in sound quality.
What the Rose Technics Ceramics does well: A broadly balanced tuning with a preference score of 72 against the Harman target. The catch: An uneven response, 2.2 dB standard deviation from target.
What the CCA C10 does well: Bass reaches all the way to 20 Hz within half a decibel of target on average, with a 3 dB lift from 60 to 200 Hz that gives drums and bass guitar body. The catch: Across nine hobbyist measurements on squig.link a 7.5 dB peak near 8.1 kHz stands out, which can make cymbals and sibilance splashy.
Buy the Rose Technics Ceramics. It is rated higher for sound quality, and the $15.10 saving on the CCA C10 is not enough to make up the difference.

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 Rose Technics Ceramics from achoreviews, audioamigo, musicafe, pw and soundignity; the CCA C10 from aftersound, bedrock, eplv, flare, hbb, melatonin, rg, soundignity and superreview, all via squig.link.
