64 Audio Fourté Blanc - Limited Edition Four Hybrid Drivers Universal IEM Earphones

64 Audio Fourté Blanc

64 Audio's second reinterpretation of the world renown Fourté; the first fully tubeless universal in-ear monitor. Rounding off Fourté’s industry leading legacy, Blanc delivers a fresh perspective, both cosmetically and technically. A custom designed open dynamic driver, one balanced armature, and two tia drivers challenge the technical possibilities of a four driver system. This culmination of small yet powerful details all build upon the wide resolving nature of the tia system, bringing recorded music to life.

Blanc is tuned very similarly to Fourté Noir, with some subtle improvements in the low-frequency band due to a new implementation of the dynamic driver, resulting in lower distortion. Lows reach deep while maintaining realism, giving space for upper bass and mid-range punch/presence. This accuracy in the mid band is not only a result of its own amplitude but because of the quick transient response of the high-mid section. The high-frequency band is left sounding pure and clean.

Tia’s classic sound-stage presents the depth of the stereo field rather than just the width. Recordings with sudden wide panned instruments seemingly come from behind the listening position. Perception of effects and tiny details are deepened. Vocals are centered yet tucked to the back of your head, giving them space while gluing them into the mix.

Hear. Feel. Create.

Limited Edition - 500 Worldwide
Limited and minimal in nature, each Fourté Blanc is one of only 500 units; all with exclusive packaging and upgraded internal components contained within a pristine white ceramic-coated shell. Internally, everything from the driver choice and position to the solder is meticulously engineered. These are beautifully juxtaposed with the unique patina of Blanc’s copper faceplate, the cloth pattern and letter pressing on the packaging; all imperfect in their own way giving each Fourté Blanc customer a truly exclusive experience.

Dynamic Driver Upgrade
The redesigned filter is a high precision textile mesh material which reduces distortion by half and improves linearity in Fourté Blanc. This is due to the reduction of back pressure on the driver and quelling of all turbulence effects between the filter and driver cone. The result is significant and measurable improvement.

Shielded Cable
In addition to the 3.5mm Pearl Premium Cable, Blanc includes an exclusive new 4.4mm Balanced Shielded Silver-Core Cable. The pure silver shield acts as a Faraday cage effective against electric fields while reflecting electromagnetic radiation and reducing interference from outside noise onto the signal.

White Ceramic Coating
Ceramic coating is used to execute the pristine white colour of Blanc’s shell since there are currently no good white PVD or anodizing alternatives which would achieve the shade of white required. The coating is a custom mixture that is applied in-house. The shell is first prepped and anodized to harden and insulate the aluminium, which would otherwise be soft and conductive.

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 Blanc all the way down to the way the shell is milled, offering similar pressure release and isolation to the 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. Fourté Blanc utilizes the complete Tia system; its four drivers radiate freely into the Tia bore with no obstructions to the drivers.
