Short answer: a tie on sound quality. Both are rated 3.9/5 (#474 and #542 of 1291 in-ear headphones) at nearly the same price ($345 vs $349), so choose on features and fit.
What the DUNU DN242 does well: The median of 4 hobbyist measurements gives it a solid Harman preference score of 73 with a 1.90 dB spread, and its mids sit within about 1.3 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 4.6 dB low with a 5.9 dB dip near 3.6 kHz, so vocals and instruments lose some bite.
The case for the ISN H60: A broadly balanced tuning with a preference score of 72 against the Harman target. The catch: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the DUNU DN242 or the ISN H60 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.
