Short answer: the Tripowin Vivace. It ranks #385 of 1291 in-ear headphones by sound quality, rated 4.0/5, at $29.90; the Tripowin x 0diBi Vivace ranks #535, rated 3.9/5, at $29.90. Close enough in price that the sound-quality gap is the deciding factor.
Why pick the Tripowin Vivace: The median of 5 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.82 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 3.1 dB low with a 5 dB dip near 10.0 kHz, so vocals and instruments lose some bite.
Why pick the Tripowin x 0diBi Vivace: A very cheap single dynamic IEM tuned with 0diBi. Watch for: A 1.88 dB spread from the target still leaves some peaks and dips.
Buy the Tripowin Vivace. It is rated higher for sound quality than the Tripowin x 0diBi Vivace 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.
