Short answer: the BGVP Solomon. It ranks #72 of 1291 in-ear headphones by sound quality, rated 4.6/5, at $229. The Simgot SuperMix 5 ranks #98, rated 4.5/5, at $219.99, $9.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the BGVP Solomon does well: Six hobbyist measurements on squig.link put its preference score at 81.1, with bass and low mids within about 1 dB of target and sub-bass holding flat to 20 Hz. The tradeoff: The presence region sits about 2.2 dB below target with a 3.9 dB dip near 3.1 kHz, so vocals and guitars can sound set back behind the bass and treble.
Why pick the Simgot SuperMix 5: Its five driver hybrid scores 80.1 for preference across 22 squig.link measurements, with a 1.24 dB deviation that keeps the whole range smooth. Watch for: Presence and treble sit about 2.5 dB below target from 3 to 10 kHz with a 3.9 dB dip near 6.1 kHz, so the sound is a bit laid back and cymbals lack bite.
Buy the BGVP Solomon. It is rated higher for sound quality, and the $9.01 you would save on the Simgot SuperMix 5 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.
