Short answer: the 64 Audio Volur. It ranks #391 of 450 in-ear headphones by sound quality, rated 3.0/5, at $2,499; the Shure KSE1500 ranks #405, rated 2.8/5, and costs $2,999, which makes this an easy call rather than a real tradeoff.
What the 64 Audio Volur does well: 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. Watch for: 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.
What the Shure KSE1500 does well: It is one of very few electrostatic in-ears, with a claimed 10 Hz to 50 kHz range. The catch: In oratory1990’s measurement the presence band from 3 to 6 kHz sits about 8.6 dB below target with a 9.5 dB dip near 4.1 kHz, which recesses vocals and instrument attack, while a 9.9 dB peak near 9.4 kHz can make cymbals and sibilance hiss.
Buy the 64 Audio Volur. It is rated higher for sound quality than the Shure KSE1500 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Headphones In Full
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.

Shure KSE1500: $2,999.00 Amazon eBay
Pros: It is one of very few electrostatic in-ears, with a claimed 10 Hz to 50 kHz range. Its warm, V-shaped balance suits listeners who like low end weight paired with an emphasized top.
Cons: In oratory1990’s measurement the presence band from 3 to 6 kHz sits about 8.6 dB below target with a 9.5 dB dip near 4.1 kHz, which recesses vocals and instrument attack, while a 9.9 dB peak near 9.4 kHz can make cymbals and sibilance hiss. A preference score of 59 at such a steep price makes it hard to justify on sound alone.
