64 Audio U18s

64 Audio, the leader in custom and universal fit in-ear monitors, is proud to announce the launch of the U18s, the new audiophile-grade, universal fit 18-driver in-ear monitor. With the introduction of U18s, 64 Audio has taken the heritage of the 18-driver platform and further pushed the envelope of innovation in sound and design. The U18s combines proprietary drivers, LID technology, and a new electronic crossover network to deliver a uniquely exceptional listening experience.

64 Audio U18s includes 18 precision-balanced armature drivers per earpiece, and is handcrafted in the USA from aerospace-grade aluminium billet. CNC milled, hand blasted, fly cut, and twice anodized, the result is a striking fractal design that is inspired by nature itself.

The world's most technically advanced earphone

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. U18s features two major elements of the tia system: the tia driver and the tia single-bore design.

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 musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for U18s: mX, m15 and m20

LID®
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 18 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.

Electrical Low Pass Filter
A crossover circuit replacing traditional acoustic dampers which can introduce unwanted distortion through vibration and air turbulence. Rather than using acoustic dampers to filter unwanted frequencies after the driver produces them the electrical low pass filter lowers distortion by eliminating unwanted frequencies before they reach the driver.
