AK ZERO1 // In-Ear Monitors
Introducing the first In-Ear Monitor from Astell&Kern, the long-awaited AK ZERO1. ZERO is a number that represents the reference point, and it also means the beginning. Composed of a Micro Rectangular Planar Dynamic Driver, two BA drivers, and a 5.6 mm Dynamic Driver, the AK ZERO1 harmonizes the characteristics of each driver to deliver the most natural sound to your ears.
An ideal frequency response was created through the Cross Over Network, which is designed based on a thorough understanding of each driver’s parameters. At the same time, each driver is carefully placed in the optimal 3D position, enclosed in specifically designed acoustic chambers manufactured with precise 3D printing technology. By implementing this, Astell&Kern eliminated unnecessary movement and resonance of the drivers to ensure a stable performance.
The housing is designed with Astell&Kern's unique advanced aluminum-refining technology to keep resonance to a minimum and create the highest-quality sound.
The Micro Rectangular Planar Dynamic Driver is a specially developed driver with highly advanced technology that allows a planar driver, normally a very difficult driver to scale down, to be applied to in-ear monitors.
Two BA drivers are made using custom coil parameters and offer crystal-clear vocals with super-low distortion. The 5.6 mm Dynamic Driver has been created through a fully automated, error-free process, ensuring rich, controlled and deep low frequencies.
The Pure Silver-Coated OFC cable maximizes the performance of the Hybrid IEM AK ZERO1. It has been exquisitely crafted with high-purity silver plating and copper, and the aluminum plugs give it even more class. The MMCX connector provides the best quality, offering a long-lasting stable performance.
The Hybrid IEM AK ZERO1 is meticulously manufactured and assembled by highly experienced engineers in facilities in Japan to the highest of tolerances, achieving the highest quality possible. AK ZERO1's premium sound will open up a whole new world that you have never experienced before, elevating you beyond the boundaries of sound. This is symbolized by the bold diagonal line that crosses the product, reflecting the identity of the AK ZERO1.
