MAKE WAY FOR THE QUAD DRIVER HYBRID IN-EAR MONITOR - THE 64 AUDIO U4S

64 Audio has been the pioneer and has developed some of the most spectacular in-ear monitors. With years of research & development, 64 Audio is proud to introduce its latest offering - the quad driver hybrid in-ear monitor U4s. It features ground-breaking patented technologies developed for its flagship products to bring a wider audience closer to its music. The 64 Audio U4s is a hybrid quad driver universal IEM that is sure to please that discerning audiophile in you.

FEATURES QUAD DRIVER SETUP TO MAKE YOUR MUSIC BREATHE AND COME ALIVE

The 64 Audio U4s has a unique driver configuration consisting of a single dynamic driver, two balanced-armature drivers, and one patented tia driver; all weaved together with their patented Tia, LID, and Apex technology. By effortlessly providing a physically compelling sub-bass without bleed-in to the mid-bass, U4s sounds light on its feet. At all volume levels, a wide range of musical genres and recording methods respond well to balanced mid frequencies and a pleasing high-mid band that is present but not oppressive. U4s makes your music breathe and come alive!

PATENTED TIA TECHNOLOGY FOR AN EVEN MORE REFINED PERFORMANCE

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. Open-balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers make up the three main components of the tia system. The U4s feature two elements of the tia system: the tia driver and the tia single-bore design. Get the most refined performance ever imaginable with the U4s!

Headphone-Zone-64 Audio - U4s

UNIQUE CROSSOVER CIRCUIT AND LINEAR IMPEDANCE DESIGN FOR CONSISTENT AND RELIABLE SOUND

A crossover circuit replaces 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. Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver sets comprising this 4-driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency responses 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. The four-way crossover is elevated with the use of our proprietary electronic low-pass filter, reducing low-frequency distortion.

Headphone-Zone-64 Audio - U4s

ELEGANT BLUE SHELLS WITH A UNIQUE FACEPLATE DESIGN

The 64 Audio U4s explores a bold new colour aesthetic. The Slate Blue shell colour is influenced by some of the world’s most beautiful blue-dial timepieces. Muonionalusta meteorite bits served as inspiration for the distinctive faceplate pattern. Both the faceplate and shell’s illuminant properties give it a unique tone in varying lighting conditions. The anodized aluminium shell adds to the ergonomics making the U4s highly comfortable to wear for long listening sessions.

BUNDLED WITH SILVER-PLATED COPPER CABLE AND APEX MX MODULES

The assortment of included apex modules and ear tips is an invitation to further shape the sound based on preference and source material. The ultra-low impedance premium silver-plated copper cable ensures unimpeded signal transmission. The dissemination of tia technology within 64 Audio's product range brings that classic 64 Audio sound signature to a new price point. 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. This design enables musicians and music enthusiasts to listen more comfortably for longer. The venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in four module variations for U4s: mX, m15, m20.
