Short answer: the Vision Ears EXT MK II. It ranks #500 of 1291 in-ear headphones by sound quality, rated 3.9/5, at $3,350; the Canpur CP622B ranks #550, rated 3.8/5, and costs $3,499, so there is little reason to consider the other one.
The case for the Vision Ears EXT MK II: A broadly balanced tuning with a preference score of 73 against the Harman target. The tradeoff: Treble about 2 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
The case for the Canpur CP622B: The median of 13 hobbyist measurements gives it a solid Harman preference score of 72 with a 1.92 dB spread. The catch: Presence sits about 5.2 dB low with a 7.5 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
Buy the Vision Ears EXT MK II. It is rated higher for sound quality than the Canpur CP622B and costs less, 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.
