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.

We embark on new challenges to break new boundaries and enter a new era.
The Hybrid IEM with Each Driver's AK Sound Distributed Harmoniously
The hybrid IEM AK ZERO1 focuses on combining the sounds of three unique driver technologies into one IEM.
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, we eliminated unnecessary movement and resonance of the drivers to ensure a stable performance.
The housing, which is designed with Astell&Kern's unique advanced aluminum-refining technology, keeps resonance to a minimum and creates the highest-quality sound.
Special Micro Rectangular Planar Dynamic Driver, Crisp and Dynamic Treble 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.
Single 5.6mm Dynamic Driver, Rich and Deep Bass Sound
The 5.6 mm Dynamic Driver has been created through a fully automated, error-free process, ensuring rich, controlled and deep low frequencies.
Hi-Fi Grade Pure Silver-Coated OFC 4 Core Cable (3.5mm Plug)
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.
*4.4mm balanced cable sold separately.
