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 Volur ranks #391, rated 3.0/5, and costs $2,499, which makes this an easy call rather than a real tradeoff.
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.
Why pick the 64 Audio Volur: Two 9mm dynamic drivers deliver about 3 to 4 dB of extra sub-bass and bass in HypetheSonics’ measurement, still 2 dB above target at 30 Hz, so bass-heavy music has real depth and slam. The tradeoff: A 4.6 dB dip near 3.4 kHz and a 2.4 dB shortfall across 3 to 6 kHz push vocals back behind the bass.
Buy the 64 Audio Tia Trio. It is rated higher for sound quality than the 64 Audio Volur and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
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 Volur: $2,499.00 64 Audio eBay
Pros: Two 9mm dynamic drivers deliver about 3 to 4 dB of extra sub-bass and bass in HypetheSonics’ measurement, still 2 dB above target at 30 Hz, so bass-heavy music has real depth and slam. Air above 10 kHz rises about 5.5 dB for shimmer on cymbals. The treble avoids sharp peaks, topping out at 3.8 dB near 11.9 kHz, so it stays easy to listen to at volume. At 103 dB/mW a phone drives it adequately.
Cons: A 4.6 dB dip near 3.4 kHz and a 2.4 dB shortfall across 3 to 6 kHz push vocals back behind the bass. A 1.9 dB lift in the lower mids adds thickness that can muddy dense mixes. The 64 Audio U12t and Fir Audio e12 both rate higher for less money.
