tia Fourté

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. The earphones are machined out of a solid piece of aluminum for a durable yet elegant look with 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 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. Get ready to hear detailed highs like you've never experienced before thanks to a custom open balanced armature tia high driver. Additionally, internal apex™ technology helps to vent air pressure from inside the ear canal for fatigue-free listening. We broke all the rules and started from scratch to come up with the tia Fourté and still managed to fit this ground breaking technology into a shell that's smaller and more ergonomic than our Universal-Fit 12 driver model.

Internal Apex Tia High Driver

Features

3D SOUND
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
CROSSOVER
A passive crossover network that directs frequencies to drivers that are optimized for their reproduction.
CENTER DRIVE
A superior balanced armature driver design that pushes the diaphragms in the center. This yields a deeper, more dynamic bass response.
NOISE ISOLATION
The capability of the earphones to reduce ambient or stage noise when properly inserted.
DRIVER CONFIG
The configuration and arrangement of drivers per frequency band.
FREQUENCY RESPONSE
The range of frequencies that the earphone is able to produce under typical use.
IMPEDANCE
The load or resistance that the earphone will present to an amplifier. Lower resistance is much easier to drive than high resistance.
tia SINGLE-BORE
The single-bore design is a huge leap 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.
TRUE PHASE
ApexTM restores proper phase response at the eardrum by switching from pressure-based amplitude to velocity- based amplitude.
APEXTM
A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement.
SENSITIVITY
The Sound Pressure Level (SPL) produced per 1mW of input power. The higher the sensitivity the less power is required to drive the earphones.
ALUMINUM BODY
The body of the earphones are machined out of a solid piece of aluminum for ultimate durability and feature a beautiful matte finish.
tia SYSTEM
A tubeless system which include: tia™ drivers, tia single-bore, tia acoustic chambers, and a passive radiator system. The absence of sound restricting tubes yields an incredibly smooth and musical frequency response and enables a larger depth and soundstage than the conventional system.
