Short answer: a tie on sound quality. Both are rated 4.7/5 (#26 and #28 of 450 in-ear headphones), so choose on features and fit.
The case for the Aoshida E20: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. The catch: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings.
The case for the Simgot EW200: Crinacle’s measurement gives it an excellent preference score of 82, and the median of 37 hobbyist measurements on squig.link keeps every band from sub-bass to presence within about 1.5 dB of target, so music sounds natural and balanced across genres. 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 Aoshida E20 or the Simgot EW200 on features: they are rated the same for sound quality at close to the same price.

Aoshida E20: $22.99 Amazon eBay
Pros: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. Sub-bass sits within a decibel of target down to 30 Hz, and the mids stay within about 1 dB, so vocals sound natural with solid bass underneath. Its dual dynamic driver design and budget price make it a sensible pick for warm or mildly V shaped tastes.
Cons: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings. Bass from 60 to 200 Hz runs about 1 dB lean, so it has less punch than bass focused alternatives. It is rated level with similarly priced rivals such as the KZ EDZ and DDHiFi Janus 3 rather than above them.

Simgot EW200 AliExpress eBay
Pros: Crinacle’s measurement gives it an excellent preference score of 82, and the median of 37 hobbyist measurements on squig.link keeps every band from sub-bass to presence within about 1.5 dB of target, so music sounds natural and balanced across genres. Sub-bass holds right to 20 Hz with only 0.2 dB of shortfall at 30 Hz, giving kick drums real depth, and a 1.56 dB spread marks an unusually smooth response. Its 16 ohm load and 126 dB/V sensitivity let it run loud from any phone.
Cons: 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. The 1.5 dB bass lift gives a slightly warm tilt that strict neutral purists may not want.
