Short answer: a tie on sound quality. Both are rated 3.9/5 (#298 and #312 of 450 in-ear headphones) at nearly the same price ($20.99 vs $23), so choose on features and fit.
The case for the CCA CRA: 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 catch: 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 CCA CRA or the Sony WI-C100 on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
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.
