From 64 Audio

The pinnacle of in-ear monitor technology, tia Fourté takes full advantage of everything we've learned up to this point in designing world-class in-ear monitors. Tia Fourté boasts the most accurate sound and widest soundstage of any in-ear monitor, making it the perfect choice for audiophiles seeking detailed, lifelike audio, and three-dimensional sound.

Tia Fourté features our complete, three-part tia™ system housed in an ergonomic shell, machined from a solid piece of aluminum and finished with elegant, copper patina faceplates.


Tia Fourté features the following unique technology:


The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. All our Custom In-Ear Monitors with tia feature two major elements of the tia system: the tia driver and the tia single-bore design.

Tia Driver
An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.

Tia Single Bore
A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.
