Short answer: the CCZ CZ10 TianGong. It ranks #538 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $29.99; the Kinera Celest Wyvern Abyss ranks #577, rated 3.8/5, at $29.99. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the CCZ CZ10 TianGong: A broadly balanced tuning with a preference score of 72 against the Harman target. Watch for: An uneven response, 2.0 dB standard deviation from target.
Why pick the Kinera Celest Wyvern Abyss: The median of 15 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.07 dB spread, and its mids sit within about 0.8 dB of target, so vocals and instruments sound natural. The catch: Its 2.07 dB spread is less even than the best measured sets.
Buy the CCZ CZ10 TianGong. It is rated higher for sound quality than the Kinera Celest Wyvern Abyss 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.
