Short answer: the IOAudio Sogno. It ranks #5 of 1291 in-ear headphones by sound quality, rated 4.9/5, at $399; the Myer Audio CKLVX D62 ranks #101, rated 4.5/5, at $399. Close enough in price that the sound-quality gap is the deciding factor.
The IOAudio Sogno is the better-sounding pick. Its preference score of 88, taken from the median of six hobbyist measurements, comes with an average deviation of only about 0.8 dB, one of the most even responses among in-ears. The tradeoff: A 3.3 dB dip near 6.5 kHz next to a 3.6 dB peak near 8.1 kHz can make some cymbals and sibilants sound slightly uneven.
The case for the Myer Audio CKLVX D62: Nine hobbyist measurements on squig.link score it 79.6 for preference with a near neutral tilt and 1.59 dB of deviation. The tradeoff: Presence sits about 2.8 dB low with a 5.5 dB dip near 5.4 kHz, while a 4.8 dB peak follows at 8.1 kHz, so the treble swings between recessed vocals and occasional sibilant edge.
Buy the IOAudio Sogno. It is rated higher for sound quality than the Myer Audio CKLVX D62 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

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.
