Short answer: the Kinera Celest Wyvern Abyss. It ranks #577 of 1368 in-ear headphones by sound quality, rated 3.8/5, at $29.99; the Tripowin x HBB Kailua ranks #707, rated 3.6/5, at $28.99. The price gap is small enough that the sound-quality ranking should decide it.
What the Kinera Celest Wyvern Abyss does well: 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. Watch for: Its 2.07 dB spread is less even than the best measured sets.
The case for the Tripowin x HBB Kailua: The median of 12 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.17 dB spread, and its mids sit within about 0.7 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 3.3 dB low with a 5.7 dB dip near 10.0 kHz, so vocals and instruments lose some bite.
Buy the Kinera Celest Wyvern Abyss. It is rated higher for sound quality, and saving $1 with the Tripowin x HBB Kailua does not make up for the sound-quality gap.

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.
