Short answer: the ThieAudio Origin. It ranks #922 of 1369 in-ear headphones by sound quality, rated 3.3/5, at $849; the Yanyin Carmen ranks #1051, rated 3.1/5, at $849. With prices this close, go by the sound-quality ranking rather than the cost.
The case for the ThieAudio Origin: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. Watch for: Presence sits about 5.1 dB low with a 5.9 dB dip near 3.9 kHz, so vocals and instruments lose some bite.
Why pick the Yanyin Carmen: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: Treble about 7 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the ThieAudio Origin. It is rated higher for sound quality than the Yanyin Carmen at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

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.
