Short answer: a tie on sound quality. Both are rated 4.6/5 (#39 and #47 of 450 in-ear headphones), so choose on features and fit.
What the DUNU Kima Classic does well: Across 10 hobbyist measurements on squig.link it earns a preference score of 81.6 with only 1.22 dB of deviation, so the tuning stays close to what most listeners prefer from deep bass through the upper mids. Watch for: A 6.6 dB dip near 10.9 kHz takes some sparkle and shimmer off cymbals.
The case for the ThieAudio Monarch MKII: A preference score of 81 from crinacle’s measurement and just 1.45 dB of deviation make it one of the most accurate in-ears available. The catch: Those measurements show a 5.6 dB dip near 6.5 kHz and treble about 2.6 dB below target, which softens cymbal attack slightly.

The Two Headphones In Full
DUNU Kima Classic: $22.99 Amazon eBay
Pros: Across 10 hobbyist measurements on squig.link it earns a preference score of 81.6 with only 1.22 dB of deviation, so the tuning stays close to what most listeners prefer from deep bass through the upper mids. Bass sits about 1.2 dB above target and sub-bass reaches 20 Hz without rolling off, giving kick drums real weight without muddying vocals. The single 10mm dynamic driver at 32 ohms and 108 dB plays loudly from a phone dongle, and it carries a higher rating than the pricier KBEAR KB01.
Cons: A 6.6 dB dip near 10.9 kHz takes some sparkle and shimmer off cymbals. There is no inline microphone, so it cannot double as a calling headset.

ThieAudio Monarch MKII AliExpress eBay
Pros: A preference score of 81 from crinacle’s measurement and just 1.45 dB of deviation make it one of the most accurate in-ears available. Across 19 hobbyist measurements on squig.link, sub-bass and bass sit within half a dB of target down to 20 Hz, so kick drums and synth bass have full, tight weight. Its 108 dB/mW sensitivity and 36 ohm impedance mean a phone drives it easily, and the hybrid layout combines a dynamic woofer, six balanced armatures and two electrostatic tweeters.
Cons: Those measurements show a 5.6 dB dip near 6.5 kHz and treble about 2.6 dB below target, which softens cymbal attack slightly. Air above 10 kHz rises about 3.4 dB over target, peaking near 11.8 kHz, which listeners sensitive to treble may hear as a touch of glare.
