Short answer: the Sony WF-1000XM5. It ranks #163 of 1291 in-ear headphones by sound quality, rated 4.4/5, at $248; the DUNU PRS6 ranks #232, rated 4.3/5, and costs $249, which makes this an easy call rather than a real tradeoff.
Why pick the Sony WF-1000XM5: Mild bass emphasis, about 1.9 dB above target from 60 to 200 Hz, adds warmth without muddying the midrange, which stays within 0.8 dB of the target for a preference score of 78. The catch: Treble from 6 to 10 kHz runs about 2.2 dB low, with a 4.9 dB dip near 8 kHz, so cymbals and sibilance lose some bite.
What the DUNU PRS6 does well: The median of 3 hobbyist measurements gives it a very good Harman preference score of 77 with a 1.78 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Presence sits about 3.7 dB low with a 6.2 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
Buy the Sony WF-1000XM5. It is rated higher for sound quality than the DUNU PRS6 and costs less, so only choose the other one for a particular feature it does better.

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.
