Short answer: a tie on sound quality. Both are rated 3.9/5 (#486 and #517 of 1291 in-ear headphones) at nearly the same price ($100 vs $103.50), so choose on features and fit.
Why pick the Audio-Technica ATH-CKR7TW: Crinacle’s measurement gives it a solid Harman preference score of 73 with a 2.18 dB spread. Watch for: Its 2.18 dB spread is less even than the best measured sets.
Why pick the DUNU Kima 2: The median of 20 hobbyist measurements gives it a solid Harman preference score of 72 with a 2.32 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The tradeoff: Presence sits about 3.2 dB low with a 5.6 dB dip near 10.3 kHz, so vocals and instruments lose some bite.
Buy the Audio-Technica ATH-CKR7TW or the DUNU Kima 2 on features: they are rated the same for sound quality at close to the same price.
