Short answer: a tie on sound quality. Both are rated 4.3/5 (#206 and #218 of 1291 in-ear headphones) at nearly the same price ($49.99 vs $51.99), so choose on features and fit.
Why pick the CCA Rhapsody: Two dynamic drivers and four balanced armatures deliver a preference score of 77 at a budget price, with an average deviation of only 1.5 dB from target in squig.link hobbyist measurements. Watch for: A 4.3 dB peak near 8 kHz and air about 4.6 dB over target can make cymbals and sibilance sound sharp on bright recordings.
The case for the TKZK Ouranos: The median of 6 hobbyist measurements gives it a very good Harman preference score of 77 with a 1.71 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Watch for: A 4.2 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the CCA Rhapsody or the TKZK Ouranos on features: they are rated the same for sound quality at close to the same price.

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.
