A recessed tube system keeps sweat away and alleviates the need for excessive cleaning.Each Layla AION begins as a carbon fiber block formed by compressing hundreds of layers of resin-infused carbon fiber fabric. After undergoing an initial machining process, and then a secondary hand shaping process, Layla AION is precision tuned using state-of-the-art equipment and assembled by hand. A striking faceplate design of red and black pearloid with oversized chrome logos makes Layla AION one of the most visually appealing universal fit earphones yet.A high purity OFC 4N silver-plated cable with German-made, military grade, iridium connector creates a tight grip at connection, while easing insertion and removal.The built-in O-ring keeps the connection between the cable and the earpiece completely sweatproof. This robust cable will not oxidize and features upgraded memory wire around the ear.Layla AION universal fit earphones are manufactured in Orlando, Florida by the same talented engineers and technicians responsible for producing Jerry Harvey Audio’s line of custom earphones, seen in thousands of ears and on professional stages around the world.
