Short answer: a tie on sound quality. Both are rated 4.3/5 (#232 and #237 of 1291 in-ear headphones) at nearly the same price ($249 vs $244.99), so choose on features and fit.
The case for the DUNU PRS6: 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 tradeoff: Presence sits about 3.7 dB low with a 6.2 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
What the Samsung Galaxy Buds4 Pro does well: A pair of 0 lbs (5.1 g) ANC earbuds with IP57 protection and a 76.9 preference score from a smooth 1.6 dB deviation. The tradeoff: A 4.2 dB dip near 2.3 kHz and presence about 2.3 dB under target take some clarity and bite off vocals and guitars.
Buy the DUNU PRS6 or the Samsung Galaxy Buds4 Pro on features: they are rated the same for sound quality at close to the same price.
