Short answer: the Simgot SuperMix 4. It ranks #18 of 450 in-ear headphones by sound quality, rated 4.8/5, at $169.99; the SeeAudio Yume ranks #29, rated 4.7/5, at $169. The price gap is small enough that the sound-quality ranking should decide it.
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. Watch for: 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.
Why pick the SeeAudio Yume: A preference score of 82 in HypetheSonics’ measurement with a smooth 1.49 dB standard deviation from target. Watch for: Presence sits about 3.2 dB below target from 3 to 6 kHz with a 4.3 dB dip near 4.3 kHz, so vocals and guitars lose a little bite, while a 4.7 dB peak near 8.5 kHz can make some cymbals stand out.
Buy the Simgot SuperMix 4. It is rated higher for sound quality, and saving $0.99 with the SeeAudio Yume does not make up for the sound-quality gap.

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.

SeeAudio Yume: $169.00 Linsoul eBay
Pros: A preference score of 82 in HypetheSonics’ measurement with a smooth 1.49 dB standard deviation from target. Bass reaches 20 Hz within about 1 dB of target and the mids from 200 Hz to 3 kHz stay within 0.2 dB, so the sound is balanced and natural. Its hybrid of one dynamic driver and two balanced armatures rates above the Final Audio A4000 and Shuoer S12.
Cons: Presence sits about 3.2 dB below target from 3 to 6 kHz with a 4.3 dB dip near 4.3 kHz, so vocals and guitars lose a little bite, while a 4.7 dB peak near 8.5 kHz can make some cymbals stand out. The higher rated Truthear Nova sells at about the same price.
