64 Audio tia Fourté

Overview

The 64 Audio tia Fourté is a universal-fit four-driver hybrid in-ear monitor with three balanced-armature drivers and one dynamic low-frequency driver. Its tia system combines open armatures, a single-bore design and acoustic chambers.

Internal Apex technology vents pressure from the sealed ear canal. The aluminium housings use copper-patina faceplate inlays, and the package lists a protective case, detachable 48-inch cable, dehumidifier and cleaning tool.
