Short answer: the Moondrop Chu 3. It ranks #640 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $24.99; the CCA Xyrra ranks #733, rated 3.6/5, at $24.99. Close enough in price that the sound-quality gap is the deciding factor.
Why pick the Moondrop Chu 3: The median of 16 hobbyist measurements gives it a solid Harman preference score of 70 with a 2.14 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. The tradeoff: Presence sits about 3.1 dB low with a 5.3 dB dip near 5.4 kHz, so vocals and instruments lose some bite.
What the CCA Xyrra does well: A very cheap hybrid with a dynamic driver and a balanced armature. The catch: Bass sits about 3.2 dB above target, a bass heavy balance.
Buy the Moondrop Chu 3. It is rated higher for sound quality than the CCA Xyrra at the same price, 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.
