Short answer: the Canpur CP54E. Both are rated 3.3/5 for sound quality (#930 and #903 of 1291 in-ear headphones), and the Canpur CP54E costs $1,999 against $2,299 for the 64 Audio Tia Trio, with sound quality a draw, the lower price decides it.
Why pick the 64 Audio Tia Trio: A single dynamic driver and two balanced armatures give near-neutral sub-bass down to 20 Hz and about 1.8 dB of extra bass for warmth and weight. The catch: In squig.link measurements the 3 to 6 kHz presence band sits about 4.7 dB below target with a 6.6 dB dip near 5.5 kHz, so vocals and strings can sound recessed.
The case for the Canpur CP54E: A broadly balanced tuning with a preference score of 65 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.
Buy the Canpur CP54E. Both are rated the same for sound quality, and it costs $300 less than the 64 Audio Tia Trio.

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.
