Short answer: the MEE Audio M6 Pro. Both are rated 3.8/5 for sound quality (#28 and #26 of 68 in-ear headphones), and the MEE Audio M6 Pro costs $39.99 against $48.99 for the CCA C12, and with sound quality even, the cheaper one is the better buy.
What the CCA C12 does well: A preference score of 71 in crinacle’s measurement is respectable for a hybrid with one dynamic driver and five balanced armatures. Watch for: The 2.2 dB deviation from the target shows the response still wanders, so tonal balance will not be fully natural.
Why pick the MEE Audio M6 Pro: A preference score of 71 in crinacle’s measurement is a decent result for a single 10mm dynamic driver. The tradeoff: The 100 dB/mW sensitivity is the lowest in this group, so it needs a little more volume than the hybrids.
Buy the MEE Audio M6 Pro. Both are rated the same for sound quality, and it costs $9 less than the CCA C12.

CCA C12: $48.99 Amazon eBay
Pros: A preference score of 71 in crinacle’s measurement is respectable for a hybrid with one dynamic driver and five balanced armatures. The 24 ohm impedance and 112 dB/mW sensitivity make it easy to drive from any phone. A slightly warm tilt gives it a fuller, more relaxed presentation than a bright set.
Cons: The 2.2 dB deviation from the target shows the response still wanders, so tonal balance will not be fully natural. Crowding six drivers into one housing does not translate into a score above cheaper single-driver sets like the CCA CRA, which has a higher rating.

MEE Audio M6 Pro: $39.99 Amazon eBay
Pros: A preference score of 71 in crinacle’s measurement is a decent result for a single 10mm dynamic driver. At 16 ohms and 100 dB/mW it is simple to drive from a phone, and the slightly warm tilt gives a smooth, easy listen. Its rating matches the CCA C12 and KZ ZAX.
Cons: The 100 dB/mW sensitivity is the lowest in this group, so it needs a little more volume than the hybrids. The 2.2 dB deviation from the target leaves audible coloration, and the 7Hz x Crinacle Zero 2 rates higher at a lower price.
