Tia Fourté

Regular price $3,599.00

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 sound stage 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 all three elements of our complete tia system: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers.

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.

TIA ACOUSTIC CHAMBERS

This specific structural design optimizes driver performance with precise placement of each internal component. The exact placement of each driver delivers what many describe as a three-dimensional, holographic sound stage.
Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed in the ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB), tia Fourté features an internal m20 apex module.

Only from 64 Audio, apex alleviates listener fatigue by releasing air pressure sealed in the ear canal. This venting enables musicians and music enthusiasts to listen more comfortably for longer.

Alleviate Listener Fatigue

When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.

 

Extend The Soundstage

Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.

 

High Fidelity Listening

Apex lowers decibel levels while preserving the clarity of the sounds around you, so you can stay aware of external sounds, without distracting from your music.
