Short answer: the EUIU UI-05. It ranks #659 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $99. The Soundpeats H3 ranks #763, rated 3.6/5, at $93.59, $5.41 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the EUIU UI-05: A hybrid with coaxial 10mm and 6mm dynamic drivers plus three balanced armatures. The catch: Treble sits about 3.6 dB below target, a dark, relaxed balance.
The case for the Soundpeats H3: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. The catch: Presence sits about 4.9 dB low with an 8.7 dB dip near 5.3 kHz, so vocals and instruments lose some bite.
Buy the EUIU UI-05. It is rated higher for sound quality, and the $5.41 you would save on the Soundpeats H3 does not close the 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.
