Short answer: the KZ ZVX. It ranks #264 of 450 in-ear headphones by sound quality, rated 4.0/5, at $19.99; the CCA CRA ranks #298, rated 3.9/5, and costs $20.99, so there is not much of a tradeoff to weigh.
What the CCA CRA does well: Crinacle’s measurement gives it a preference score of 72, and its deviation from target of only about 2 dB is a smooth result for such a cheap set. The tradeoff: In squig.link measurements a 7 dB peak near 8.1 kHz and about 4 dB of extra air above 10 kHz can make cymbals and sibilance sound splashy, while a 3.5 dB dip near 3.1 kHz sets vocals slightly back.
Buy the KZ ZVX. It is rated higher for sound quality than the CCA CRA and costs less, which makes it the one to get unless you need something the other one does better.

CCA CRA: $20.99 Amazon eBay
Pros: Crinacle’s measurement gives it a preference score of 72, and its deviation from target of only about 2 dB is a smooth result for such a cheap set. Across 34 hobbyist measurements on squig.link, bass sits about 3 dB above target from 20 to 200 Hz, so it suits listeners who want extra punch and rumble. At 23.5 ohms and 111 dB it plays loud from any phone or dongle, and it rates level with the KZ ZSN Pro and 7Hz x Crinacle Zero 2 while costing a little less.
Cons: In squig.link measurements a 7 dB peak near 8.1 kHz and about 4 dB of extra air above 10 kHz can make cymbals and sibilance sound splashy, while a 3.5 dB dip near 3.1 kHz sets vocals slightly back. The KZ ZSN Pro X rates a bit higher at a similar price.
