Astell&Kern x 64 Audio XIO In-Ear Monitors
3399,00 €
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.
Engineered for Precision
XIO is meticulously engineered both inside and out. Its advanced hybrid system, featuring ten high-performance drivers, is finely tuned with a 4-way passive crossover to ensure every frequency is in perfect harmony. This precise tuning delivers a realistic sense of depth and a rich, spacious soundstage.
Tia Waveguide
The tiaⓇ driver is designed with a direct-radiating structure that eliminates the traditional sound tube, enhancing the delicacy of high frequencies. This design minimizes damping and distortion, while the precisely positioned driver, together with a custom waveguide system, delivers a deep sense of space and airy, detailed highs.
BA Driver Manifold Assembly
The mid and upper-mid frequencies are powered by six and one balanced armature drivers, respectively, delivering smooth transitions and rich texture. Vocals, instruments, and their unique harmonic details are rendered warm and clear, creating a natural and well-balanced sense of space within the soundstage.
True ISOBARIC Dual Dynamic Driver
The TRUE ISOBARIC structure features two dynamic drivers perfectly synchronized within an acoustically neutral coupling chamber, enabling precise control. This design delivers bass with exceptional depth and density, as well as powerful sound impact – surpassing what is typically possible with conventional IEMs.
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.
The faceplate exhibits Astell&Kern’s design heritage, projecting a three-dimensional and elegant presence through deep shading and delicate reflections.
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.
Handcrafted IEM Made in the USA
64 Audio uses carefully selected components sourced from trusted partners around the world. Every step of design, assembly, and quality control is meticulously carried out by skilled engineers in the United States.
