Featuring a hybrid multidriver system, the ATH-IEX1 in-ear headphones deliver smooth, natural sound reproduction across the entire frequency range, with the capacity for reproducing Hi-Res Audio. Contained within the headphones’ solid titanium housings are dual phase drivers of different diameters (9.8 mm and 8.8 mm) plus two balanced armature drivers, positioned on a coaxial line. The 9.8 mm works as a full-range driver, while the 8.8 mm functions as a passive radiator to strengthen the lower frequency. Those two units face each other, their diaphragm movements syncing to minimize distortion and provide audio that is true to the original sound. The balanced armature drivers act like super tweeters to contribute accurate, high-frequency reproduction.

The elegant, ergonomic housings are crafted through a five-step process: They are cut from solid titanium, forged, machined using a precise CNC machining process, carefully hand-polished, and given an anodized finish. The result is lightweight, rigid housings that greatly reduce unwanted resonance for the highest sonic purity, and that fit comfortably and securely in the ear. The two-position eartip post on each housing allows for customized positioning of the eartip for an even better fit.
