Product Description

Fourté is the pinnacle of in-ear monitor technology. With its entire design being made up of industry firsts, Fourté isn’t just a four driver hybrid UIEM. The innovations of acoustically shaping micro-chambers, direct radiating drivers, and the single sound bore come together in our patented tia technology. Fourté is our first IEM to feature internally integrated patented apex technology. These along with its ergonomic shell, machined out of solid aluminum, have dictated our entire UIEM design language since its development in 2016.

Sound
"It truly amazes me how easily the Fourté reproduces every single note of each track I fire through it. Nothing gets overshadowed, everything is just there and sounds perfectly clean with incredible separation."
– Linus (Headfonia)

"From initial listening, the sound is incredibly impressive. The Fourté is able to resolve and emit an orchestra of sound like no other. The separation, detail, attack along with the larger than life sound and undercurrents of the dynamic driver bass, consolidate its TOTL status immediately."
– Smit Patel (Enjoy the Music)

"To say these are airy doesn’t cover it by half. The emphasis on upper treble, combined with the sheer audacity of its extension, blows the roof wide open, letting in unimaginable air and height."
– Pinky Powers (The Headphone List)

The black anodized aluminium shell is topped off with a copper colour anodised aluminium faceplate and a beautifully aged copper faceplate chip; each one developing a truly unique patina pattern making sure that no two Fourté are alike. Fourté’s unique drivers, acoustic chambers, integrated apex technology and passive radiator all unite delivering an unrivaled sonic experience. The level of detail retrieval coupled with its “out-of-head” sound-stage and deep reaching bass reanimate well-recorded music; putting its resolving capabilities at the level of some of the worlds greatest audiophile systems.

Technology

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.

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. A12t features two major elements of the tia system: the tia driver and the tia single-bore design.
