Short answer: the ThieAudio Legacy 4. It ranks #30 of 1291 in-ear headphones by sound quality, rated 4.8/5, at $50.99. The Simgot EW200 ranks #44, rated 4.7/5, at $45, $5.99 cheaper, which does not close the gap in sound quality.
The case for the ThieAudio Legacy 4: The Legacy 4 pairs one dynamic driver with three balanced armatures, and the median of twelve hobbyist measurements on squig.link shows bass essentially on target, slightly above it at 30 Hz. Watch for: A 4.3 dB dip near 3.75 kHz and a presence band about 2.3 dB low can push vocals back and soften the attack of guitars and snares.
The case for the Simgot EW200: A single dynamic in-ear with an excellent 82 Harman preference score and an unusually smooth 1.56 dB spread from target. Watch for: A 3.5 dB peak near 8.1 kHz and air about 2.3 dB above target can make cymbals and sibilance a little crisp for treble-sensitive listeners.
Buy the ThieAudio Legacy 4. It is rated higher for sound quality, and saving $5.99 with the Simgot EW200 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.
