Short answer: the 64 Audio Tia Trio. It ranks #373 of 450 in-ear headphones by sound quality, rated 3.3/5, at $2,299. The 64 Audio U12t ranks #381, rated 3.2/5, at $1,999, $300 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for 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 tradeoff: 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.
What the 64 Audio U12t does well: 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. The catch: 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 64 Audio Tia Trio. It is rated higher for sound quality, and the $300 you would save on the 64 Audio U12t does not close the gap.

64 Audio Tia Trio: $2,299.00 64 Audio eBay
Pros: 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. Air above 10 kHz rises about 4.9 dB, giving cymbals shimmer and a sense of space. At 104 dB/mW it runs fine from a phone. It rates above the 64 Audio U12t and the SoftEars Cerberus.
Cons: 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. A 5.9 dB peak near 11.9 kHz may add a touch of sizzle. The 64 Audio A12t from the same maker earns the same rating for less money.

64 Audio U12t: $1,999.00 64 Audio eBay
Pros: 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. In the median of 22 hobbyist measurements on squig.link, the treble never rises more than a fraction of a decibel above target between 1.5 and 12 kHz, so there is no harshness or sibilance at any volume. At 108 dB/mW it plays loud from a phone. It matches the rating of the SoftEars Cerberus for less money.
Cons: 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. The 64 Audio A12t from the same maker rates higher at the same price, and the Fir Audio e12 matches its rating for less.
