The 64 Audio tia Fourté™ is a first-of-its-kind universal-fit earphone that takes full advantage of the patent pending tia™ system and everything we’ve learned up to this point in designing world-class in-ear monitors.
Tubeless in-ear audio
An industry first technology featuring a tubeless system with the all-new tia drivers
The tia driver is an open balanced armature speaker design that brings new meaning to resolution and transparency, like most hi-fi speaker designs, produces the sound with the direct-radiating, fully unobstructed diaphragm. This eliminates a lot of the vibrations and resonances
Ground breaking technology such as frequency-shaping acoustic chambers in combination with an internal passive radiator that help to craft a visceral low end, smooth mids, and a luscious 3D soundstage.
Internal apex™ technology helps to vent air pressure from inside the ear canal for fatigue-free listening
