Short answer: a tie on sound quality. Both are rated 4.8/5 (#23 and #18 of 450 in-ear headphones), so choose on features and fit.
Why pick the Simgot EW100P: In oratory1990’s measurement it earns a preference score of 83 with a deviation of only 1.49 dB, so its single 10mm dynamic driver tracks the Harman target unusually closely. Watch for: A 5.8 dB dip near 9.7 kHz and treble running about 2.4 dB under target between 6 and 10 kHz soften cymbals and string texture, while the 10 to 16 kHz air region is 3.6 dB hot.
Why pick the Simgot SuperMix 4: Across 48 hobbyist measurements on squig.link it scores 83 for preference, with an average deviation of only about 1 dB, so the overall balance is even and easy to like. The tradeoff: A roughly 3 dB dip near 6.5 kHz and a presence region about 2 dB under target make vocals and guitar attack a touch recessed, while a 5.7 dB peak near 11.9 kHz adds a hint of glare up top.
Buy the Simgot EW100P or the Simgot SuperMix 4 on features: they are rated the same for sound quality at close to the same price.

Pros: In oratory1990’s measurement it earns a preference score of 83 with a deviation of only 1.49 dB, so its single 10mm dynamic driver tracks the Harman target unusually closely. Bass and low mids sit within 1 dB of target and sub-bass is only 2.4 dB down at 30 Hz, giving kick drums real weight without boom. At 32 ohms and 122 dB sensitivity it reaches loud levels from a phone or a basic dongle.
Cons: A 5.8 dB dip near 9.7 kHz and treble running about 2.4 dB under target between 6 and 10 kHz soften cymbals and string texture, while the 10 to 16 kHz air region is 3.6 dB hot. It is wired only and has no microphone for calls.

Simgot SuperMix 4: $169.99 Amazon eBay
Pros: Across 48 hobbyist measurements on squig.link it scores 83 for preference, with an average deviation of only about 1 dB, so the overall balance is even and easy to like. Sub-bass sits about 1 dB above target down to 20 Hz, giving warm, full low end that suits bass and warm listeners. The 7.2 ohm, 120 dB/Vrms hybrid of dynamic, balanced armature, planar and piezoelectric drivers gets loud from any phone or dongle.
Cons: A roughly 3 dB dip near 6.5 kHz and a presence region about 2 dB under target make vocals and guitar attack a touch recessed, while a 5.7 dB peak near 11.9 kHz adds a hint of glare up top. Its rating sits below the EPZ P40 at a similar price, and its very low impedance can pick up hiss from noisy sources.
