Short answer: a tie on sound quality. Both are rated 3.8/5 (#544 and #573 of 1291 in-ear headphones) at nearly the same price ($249.99 vs $249.99), so choose on features and fit.
What the DUNU DN142 does well: The median of 11 hobbyist measurements gives it a solid Harman preference score of 72 with a 1.89 dB spread, and its mids sit within about 1 dB of target, so vocals and instruments sound natural. Watch for: Presence sits about 3.4 dB low with a 6.4 dB dip near 6.7 kHz, so vocals and instruments lose some bite.
Why pick the Simgot ET142: The median of 17 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.07 dB spread. Watch for: A 7.9 dB peak near 7.9 kHz can make cymbals and sibilance sound sharp.

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.
