Short answer: the ROSESELSA Distant Mountain. It ranks #223 of 481 over-ear headphones by sound quality, rated 3.6/5, at $55.99; the Audio-Technica ATH-M20x ranks #293, rated 3.3/5, and costs $59, which makes this an easy call rather than a real tradeoff.
The ROSESELSA Distant Mountain is the better-sounding option. A broadly balanced tuning with a preference score of 73 against the Harman target. Watch for: About 5 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music.
Why pick the Audio-Technica ATH-M20x: The response is gentle in the midrange, with upper mids within about half a dB of target, so voices sit naturally. The catch: Sub-bass under 60 Hz is about 7 dB below target, so deep synth bass and kick drums lack rumble.
Buy the ROSESELSA Distant Mountain. It is rated higher for sound quality than the Audio-Technica ATH-M20x and costs less, which makes it the one to get unless you need something the other one 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.
