Short answer: the CCA C10. It ranks #630 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $24.89; the Kiwi Ears x B Media Chorus ranks #831, rated 3.5/5, and costs $39.99, which makes this an easy call rather than a real tradeoff.
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 tradeoff: 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.
Why pick the Kiwi Ears x B Media Chorus: A single 10 mm dynamic driver with mid-bass about 3.7 dB above target gives a warm, punchy sound that suits warm and bassy listeners, and bass holds within 6 dB of target down to 20 Hz. The tradeoff: A Harman preference score of 67.4 in hobbyist measurements points to a colored tuning, with a 4.4 dB dip near 6.1 kHz that dulls instrument edge and a 5.2 dB peak near 8.1 kHz that can make cymbals splashy.
Buy the CCA C10. It is rated higher for sound quality than the Kiwi Ears x B Media Chorus 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.
