Short answer: the Tripowin x 0diBi Vivace. It ranks #535 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $29.90; the Kinera Celest Wyvern Abyss ranks #577, rated 3.8/5, and costs $29.99, which makes this an easy call rather than a real tradeoff.
The case for the Tripowin x 0diBi Vivace: A very cheap single dynamic IEM tuned with 0diBi. The tradeoff: A 1.88 dB spread from the target still leaves some peaks and dips.
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. The catch: Its 2.07 dB spread is less even than the best measured sets.
Buy the Tripowin x 0diBi Vivace. It is rated higher for sound quality than the Kinera Celest Wyvern Abyss and costs less, so only choose the other one for a particular feature it does better.

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.
