Short answer: the Kiwi Ears Orchestra. Both are rated 3.9/5 for sound quality (#506 and #510 of 1291 in-ear headphones), and the Kiwi Ears Orchestra costs $662.56 against $699.99 for the DUNU Zen, and with sound quality even, the cheaper one is the better buy.
Why pick the DUNU Zen: Crinacle’s measurement earns it a preference score of 72, and squig.link measurements show a warm, slightly bass-lifted tuning with bass about 1.6 dB above target that suits warm and bassy tastes. The catch: Air above 10 kHz falls about 8 dB short of target, with an 11 dB hole near 11.9 kHz, so the top end sounds rolled off and lacks shimmer.
Why pick the Kiwi Ears Orchestra: Eight balanced armatures per side earn a preference score of 72 in crinacle’s measurement. The tradeoff: Presence sits 5.5 dB below target with a 6.7 dB dip near 5.3 kHz, which pushes vocals and guitar bite back and makes some recordings sound distant.
Buy the Kiwi Ears Orchestra. Both are rated the same for sound quality, and it costs $37.43 less than the DUNU Zen.

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.
