Short answer: a tie on sound quality. Both are rated 3.9/5 (#517 and #541 of 1291 in-ear headphones) at nearly the same price ($103.50 vs $99), so choose on features and fit.
What the DUNU Kima 2 does well: The median of 20 hobbyist measurements gives it a solid Harman preference score of 72 with a 2.32 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 3.2 dB low with a 5.6 dB dip near 10.3 kHz, so vocals and instruments lose some bite.
Why pick the qdc SUPERIOR: A broadly balanced tuning with a preference score of 72 against the Harman target. Watch for: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the DUNU Kima 2 or the qdc SUPERIOR 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.
