Short answer: the Canpur CP54E. It ranks #930 of 1291 in-ear headphones by sound quality, rated 3.3/5, at $1,999; the 64 Audio U12t ranks #945, rated 3.2/5, at $1,999. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the Canpur CP54E: A broadly balanced tuning with a preference score of 65 against the Harman target. The catch: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Why pick the 64 Audio U12t: Twelve balanced armatures produce a warm, smooth tuning with sub-bass right on target down to 20 Hz and about 1.6 dB of extra bass for body. Watch for: Presence sits about 5.7 dB below target from 3 to 6 kHz, with a 7.9 dB dip near 3.3 kHz, so vocals and guitars sound distant and detail is subdued.
Buy the Canpur CP54E. It is rated higher for sound quality than the 64 Audio U12t at the same price, 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.
