64 Audio tia Fourté Universal IEM Earphones
The 64 Audio tia Fourté Universal IEM Earphones represent the pinnacle of in-ear monitor technology, featuring a groundbreaking design composed of industry-first innovations. Not merely a four driver hybrid UIEM, Fourté integrates pioneering advancements such as acoustically shaping micro-chambers, direct radiating drivers, and the single sound bore, all encapsulated within the patented tia technology. This cutting-edge design, combined with an ergonomic shell crafted from solid aluminium, has set the standard for UIEM development since its inception in 2016.
Renowned for its exceptional sound quality, the tia Fourté earphones offer unparalleled detail retrieval, expansive soundstage, and deep-reaching bass. Testimonials from industry experts attest to its remarkable performance, with phrases like "incredibly impressive" and "unrivalled sonic experience" highlighting its prowess.
The black anodised aluminium shell, complemented by a copper faceplate and a beautifully aged copper faceplate chip, ensures each pair of Fourté earphones is uniquely distinctive, developing a one-of-a-kind patina pattern over time.
Integrated with patented apex technology, the tia Fourté earphones provide a comfortable listening experience by releasing air pressure in the sealed ear canal while maintaining standard levels of isolation. This innovative venting system alleviates listener fatigue and contributes to a more realistic soundstage, ensuring prolonged enjoyment of music at the highest fidelity. Whether it's the transparent and lifelike sound signature delivered by the tia system or the pressure release and isolation facilitated by the integrated apex technology, the tia Fourté earphones stand as a testament to 64 Audio's commitment to pushing the boundaries of audio excellence.
What 64 Audio say
The black anodised 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 unrivalled 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.
Featured Technology
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 utilises the complete Tia system; its four drivers radiate freely into the Tia bore with no obstructions to the drivers.
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.
