Short answer: the Rose Technics QT9 MK3. It ranks #108 of 1291 in-ear headphones by sound quality, rated 4.5/5, at $280.99; the Myer Audio SLIIVO SL-41 Pro ranks #136, rated 4.4/5, at $279. Close enough in price that the sound-quality gap is the deciding factor.
The case for the Rose Technics QT9 MK3: The median of 4 hobbyist measurements gives it an excellent Harman preference score of 80 with a 1.44 dB spread, and its mids sit within about 1.5 dB of target, so vocals and instruments sound natural. Watch for: Its 1.44 dB spread is less even than the best measured sets.
The case for the Myer Audio SLIIVO SL-41 Pro: It scores 79.1 in the median of 4 squig.link measurements, with a 1.47 dB spread and mids that hold close to target. The catch: Presence is about 3 dB below target with a 4.7 dB dip near 3.75 kHz, which pulls vocals and guitar attack back.
Buy the Rose Technics QT9 MK3. It is rated higher for sound quality, and the $1.99 saving on the Myer Audio SLIIVO SL-41 Pro is not enough to make up the difference.

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.
