Short answer: the 7Hz Sonus II. It ranks #258 of 1291 in-ear headphones by sound quality, rated 4.2/5, at $75.99; the Simgot EG280 ranks #373, rated 4.1/5, and costs $79.99, so there is not much of a tradeoff to weigh.
The case for the 7Hz Sonus II: A hybrid dynamic and planar in-ear with a 76.5 preference score, a smooth 1.7 dB deviation and slightly warm, natural bass. Watch for: The 3 to 6 kHz presence range sits nearly 4 dB under target with a 5.2 dB dip near 6 kHz, so vocals and guitars can sound a little distant and less crisp.
What the Simgot EG280 does well: The median of 15 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.76 dB spread, and its mids sit within about 0.7 dB of target, so vocals and instruments sound natural. The tradeoff: Its 1.76 dB spread is less even than the best measured sets.
Buy the 7Hz Sonus II. It is rated higher for sound quality than the Simgot EG280 and costs less, which makes it the one to get unless you need something the other one does better.

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.
