Short answer: the 64 Audio A12t. Both are rated 3.3/5 for sound quality (#374 and #373 of 450 in-ear headphones), and the 64 Audio A12t costs $1,999 against $2,299 for the 64 Audio Tia Trio, with sound quality a draw, the lower price decides it.
What the 64 Audio A12t does well: Bass is on target down to 20 Hz with a slight 1.9 dB lift from 60 to 200 Hz, so low end feels full and solid without boom. Watch for: In the two hobbyist measurements on squig.link, treble from 6 to 10 kHz sits about 10 dB below target with a 13.7 dB dip near 8.7 kHz, and presence is 7.3 dB low, so cymbals, strings and vocal clarity sound noticeably dark and muffled.
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 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.
Buy the 64 Audio A12t. Both are rated the same for sound quality, and it costs $300 less than the 64 Audio Tia Trio.

The Two Headphones In Full
64 Audio A12t: $1,999.00 64 Audio eBay
Pros: Bass is on target down to 20 Hz with a slight 1.9 dB lift from 60 to 200 Hz, so low end feels full and solid without boom. That warm balance suits listeners who prefer a relaxed, bass rich sound for long sessions. At 12.6 ohms and 108 dB/mW it runs easily from a phone.
Cons: In the two hobbyist measurements on squig.link, treble from 6 to 10 kHz sits about 10 dB below target with a 13.7 dB dip near 8.7 kHz, and presence is 7.3 dB low, so cymbals, strings and vocal clarity sound noticeably dark and muffled. The qdc Anole V6 earns the same rating for considerably less.

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.
