64 Audio U4s

Product Overview

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. Explores a bold new color aesthetic. The Slate Blue shell color was influenced by some of the world's most beautiful blue-dial timepieces while the unique faceplate pattern is inspired by Muonionalusta meteorite fragments. Both the faceplate and shell's illuminant properties give it a unique tone in varying lighting conditions.

Technical Composition

Its ergonomic anodized aluminum 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 electrical low-pass filter; reducing low-frequency distortion.

Customization and Sound Transmission

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 sound signature to a new price-point.
