Astell & Kern x 64 Audio XIO In-Ear Monitor Earphones

Drivers are the foundational element for pristine audio reproduction. These IEMs consist of a 10-driver hybrid system, making playback incredibly efficient throughout the entire system. The low-end is handled by two TRUE ISOBARIC dynamic drivers with an acoustically neutral coupled chamber, providing superb depth and density. Midrange is powered by six balanced armature drivers that allow rich instruments like vocals and guitars to maintain their harmonic details. And finally, the Tubeless In-Ear Audio (tia) driver brings higher frequency definition by minimizing damping and unwanted distortion.

Three separate patented technologies combine to create a full-spectrum system that extends from 5 Hz to 22 kHz. The Tubeless In-Ear Audio design minimizes resonances and distortion to deliver clear sound, while the Air Pressure Exchange (apex) reduces ear fatigue and simultaneously creates a wider and more realistic soundstage.

Especially when it comes to crossover efficiency, this is no easy task. But the Linear Impedance Design (LID) is able to compensate for driver resistance, making for a more stable sound signature and frequency response.

More than just a simple design, the robust structure is crafted with 904L-grade stainless steel and finished with a beautifully luxurious black Diamond-Like Carbon coating for even higher detail.

The dedicated cable, crafted specifically for the XIO, achieves electrical efficiency with its four-core cross-braided architecture made from silver-plated, single-crystal copper. Along with a very low impedance of just 0.29 ohms, this cable provides a fully transparent signal transformation.
