One Driver. Infinite Detail

XIO is the culmination of Astell&Kern and 64Audio’s shared philosophy on design and sound. Blending precision engineering with artistic sensibility, XIO goes beyond simply playing music. It shapes sound into a tangible experience, offering value that surpasses expectations.

Designed as a true object of art, XIO sets a new standard for high-end in-ear monitors—an uncompromising fusion of aesthetics and acoustics that redefines what's possible.

Precision-milled 904L Stainless Steel Shell

The exterior of XIO goes beyond that of a typical IEM, standing out as an “audio art piece” that satisfies both visual and tactile senses.

Its robust structure is crafted by precisely machining 904L stainless steel—a material harder and more challenging to work with than standard stainless steel—and is then finished with a luxurious black DLC (Diamond-Like Carbon) coating for an exceptional premium texture.

Silver Plated UP-OCC Copper Litz Cable

This dedicated cable, specially crafted for XIO, is designed to achieve perfect aesthetic harmony with the earbuds.

The four-core cross-braided cable is made from silver-plated, single-crystal copper (UP-OCC), offering outstanding noise shielding and transparent signal transmission.

With a low impedance of just 0.29Ω, it maximizes electrical efficiency.
