Short answer: the Shure KSE1500, though neither ranks well in its class. Both are rated 2.8/5 for sound quality (#1035 and #1051 of 1291 in-ear headphones), and the Shure KSE1500 costs $2,999 against $3,599 for the 64 Audio Tia Fourte, with sound quality a draw, the lower price decides it. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the ThieAudio Monarch MKIII instead, ranked #1 at $999.
The case for the 64 Audio Tia Fourte: Lower mids sit within about 0.9 dB of target, keeping voices and guitars natural. Watch for: Presence sits about 7.1 dB low with a 10.9 dB dip near 3.5 kHz, so vocals and instruments lose some bite.
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 Shure KSE1500. Both are rated the same for sound quality, and it costs $600 less than the 64 Audio Tia Fourte.
