64 Audio is an American high-end in-ear monitor maker founded in 2010 as 1964 Ears by sound engineer Vitaliy Belonozhko, best known for custom and universal monitors used by touring musicians. Its designs feature proprietary tia (tubeless) treble drivers, Apex pressure-relief modules, and LID (Linear Impedance Design) for source-agnostic tuning.

64 Audio put a commodity planar driver in a $1,399 shell and engineered its worst habit away — and the argument about whether that's worth fourteen Chi-Fi planars has never stopped.

The IEM the hobby calls its all-rounder — agreed on bass, imaging and comfort, and still argued over at the 3 kHz dip, the tia treble and the $2,000 price.

The cheapest 64 Audio, and the one its own reviewers keep picking over the $2,000 flagship — with four screw-in modules that quietly settle most of the arguments about it.
