64 Audio U4s

The 64 Audio U4s deliver high-performance audiophile sound at a very reasonable price. They are lightweight and comfortable, great for long listening sessions!

A quad driver hybrid UIEM featuring ground-breaking patented technologies originally developed for our flagship products in order to bring a wider audience closer to their music. U4s explores a bold new colour aesthetic for 64 Audio. The Slate Blue shell colour was influenced by some of the world’s most beautiful blue- dial timepieces while the unique face-plate pattern is inspired by Muonionalusta meteorite fragments. Both the face-plate and shell’s illuminant properties give it a unique tone in varying lighting conditions.

64 Audio U4s

The 64 Audio U4s deliver high-performance audiophile sound at a very reasonable price. They are lightweight and comfortable, great for long listening sessions!

A quad driver hybrid UIEM featuring ground-breaking patented technologies originally developed for our flagship products in order to bring a wider audience closer to their music. U4s explores a bold new colour aesthetic for 64 Audio. The Slate Blue shell colour was influenced by some of the world’s most beautiful blue- dial timepieces while the unique face-plate pattern is inspired by Muonionalusta meteorite fragments. Both the face-plate and shell’s illuminant properties give it a unique tone in varying lighting conditions.

Its ergonomic anodised aluminium shell houses a single dynamic driver, two balanced-armature drivers, and one patented tia driver; all weaved together with our patented Tia, LID, and Apex technology. The four-way crossover is elevated with the use of our proprietary electronic low-pass filter; reducing low- frequency distortion.

The assortment of included apex modules and ear tips are an invitation to further shape the sound based on preference and source material while the ultra- low impedance premium silver-plated copper cable ensures unimpeded signal transmission. The dissemination of tia technology within our product range brings that classic 64 Audio sound signature to a new price-point.

U4s features the following unique technology:
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. A4s 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 available for A4s: 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 4 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.
