64 Audio tia Fourté

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 that 64 Audio has learned up to this point in designing world-class in-ear monitors. The earphones are machined out of a solid piece of aluminium for a durable yet elegant look with a beautiful copper patina finish inlayed on the faceplates. Inside, proprietary tia open balanced armatures are expertly arranged to deliver rich, natural sound in a brand new way.

Featuring groundbreaking technology such as frequency-shaping acoustic chambers in combination with an internal passive radiator that helps to craft a visceral low end, smooth mids, and a luscious 3D soundstage. Get ready to hear detailed highs as you've never experienced before thanks to a custom open balanced armature tia high driver. 64 Audio broke all the rules and started from scratch to come up with the tia Fourté and still managed to fit this groundbreaking technology into a shell that's smaller and more ergonomic than their Universal-Fit 12 driver model.

The tia Fourté features innovative apex technology. Apex (air pressure exchange) relieves air pressure caused by miniature speakers in a sealed ear canal, giving you a superior listening experience that simply cannot be achieved by traditional IEMs.

Welcome to the pinnacle of IEM design.

Tia
Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. Fourté utilizes the complete Tia system; its four drivers radiate freely into the Tia bore with no obstructions to the drivers.

Apex
Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex is integrated in Fourté all the way down to the way the shell is milled, offering similar pressure release and isolation to our m20 module.
