Short answer: the Yanyin Canon II. Both are rated 4.0/5 for sound quality (#383 and #399 of 1291 in-ear headphones), and the Yanyin Canon II costs $379 against $399 for the ThieAudio Hype 4 MKII, with sound quality a draw, the lower price decides it.
Why pick the ThieAudio Hype 4 MKII: The median of 11 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.68 dB spread. The tradeoff: Presence sits about 4.4 dB low with a 6 dB dip near 4.7 kHz, so vocals and instruments lose some bite.
Why pick the Yanyin Canon II: Its one dynamic plus four balanced armature hybrid measures a preference score of 73.9 in hobbyist squig.link measurements, with a modest 1.88 dB deviation from target. The tradeoff: The presence region from 3 to 6 kHz averages 4.2 dB below target with a 5.4 dB dip near 3.4 kHz, which pushes vocals and guitars slightly back and softens the attack of snare hits.

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.
