Short answer: the Soranik MEMS-3S 2025. It ranks #806 of 1291 in-ear headphones by sound quality, rated 3.5/5, at $1,200. The SeeAudio Neo ranks #866, rated 3.4/5, at $1,099, $101 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Soranik MEMS-3S 2025 does well: A broadly balanced tuning with a preference score of 68 against the Harman target. The catch: An uneven response, 2.3 dB standard deviation from target.
What the SeeAudio Neo does well: Bass and sub-bass sit within a decibel of target down to 20 Hz, giving a clean, controlled low end without boom. The tradeoff: Squig.link measurements show the 3 to 6 kHz presence band about 5.4 dB below target with a 9.2 dB dip near 5.5 kHz, so vocals lose clarity and instruments sound recessed.
Buy the Soranik MEMS-3S 2025. It is rated higher for sound quality, and the $101 you would save on the SeeAudio Neo does not close the gap.

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.
Measurement data: the Soranik MEMS-3S 2025 from aftersound, dchpgall, hbb and vsg; the SeeAudio Neo from aftersound, eliseaudio, hbb and timmyv, all via squig.link.
