Short answer: a tie on sound quality. Both are rated 4.2/5 (#303 and #284 of 1291 in-ear headphones), so choose on features and fit.
Why pick the Craft Ears Omnium: A broadly balanced tuning with a preference score of 76 against the Harman target. Watch for: The rating reflects sound quality only; comfort, build and noise isolation are not part of the score.
The case for the Softears Karma: The median of 6 hobbyist measurements gives it a very good Harman preference score of 76 with a 1.80 dB spread, and its mids sit within about 1.4 dB of target, so vocals and instruments sound natural. The catch: Its 1.80 dB spread is less even than the best measured sets.
Buy the Craft Ears Omnium or the Softears Karma on features: they are rated the same for sound quality at close to the same price.

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.
