Short answer: the Truthear Nova. It ranks #2 of 450 in-ear headphones by sound quality, rated 4.9/5, at $169.99; the Simgot SuperMix 4 ranks #18, rated 4.8/5, at $169.99. With prices this close, go by the sound-quality ranking rather than the cost.
The case for the Truthear Nova: A Harman score of 90 puts it among the best-tuned in-ears measured, with every band from sub-bass to presence within about 1.5 dB of the target. The tradeoff: A 2.7 dB peak near 8 kHz can make bright cymbals and sibilant vocals slightly edgy on poorly mastered tracks.
The case for 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 Truthear Nova. It is rated higher for sound quality than the Simgot SuperMix 4 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Headphones In Full
Truthear Nova: $169.99 Amazon AliExpress eBay
Pros: A Harman score of 90 puts it among the best-tuned in-ears measured, with every band from sub-bass to presence within about 1.5 dB of the target. The deviation of only 0.86 dB means vocals, guitars and drums sound natural and evenly balanced. The hybrid design pairs a dynamic driver with four balanced armatures, and the 14.8 ohm impedance with 123 dB sensitivity lets a phone drive it easily. Sub-bass sits about 1.5 dB above target, adding a touch of rumble without muddying the mids.
Cons: A 2.7 dB peak near 8 kHz can make bright cymbals and sibilant vocals slightly edgy on poorly mastered tracks. Treble and air run about 1.3 to 1.4 dB hot, so listeners sensitive to brightness may find extended sessions a little sharp. It is wired only, with no microphone or wireless features listed.

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.
