By building our experience in IEM manufacture from "ZERO" we push to make ZERO1 a truly best in class product and market leader in the Hi-Fi IEM arena.


The Hybrid IEM with each driver's AK sound harmoniously distributed
Hybrid IEM AK ZERO1 focuses on combining the sounds of three unique driver technologies into one. Composed of a Micro Rectangular Planar Dyanmic Driver, two BA drivers, and a 5.6mm Dynamic Driver, the AK ZERO1 hamonizes the characteristics of each driver to deliver the most natural sound to your ears. An ideal freuqeuncy response was created throught the Cross Over Network, which is designed based on a thorough undertsnading 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 precide 3D printing technology. By implementing this, we eliminated unnecessary movement and resonance of the drivers to ensure a stable performance.
Special Micro Rectangular Planar Dyanmic Driver Crisp and Dyanmic 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.


Dual Custom Balanced Armature Driver Transparent Vocal Sound
Two BA drivers are made using custom coil parameters and offer crystal-clear vocals with super-low distortion.
Dual Custom Balanced Armature Driver Transparent Vocal Sound
The 5.6mm 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 Cable 4 Core (3.5mm Plug)
The Pure Silver-Coated OFC cable maximises the performance of the Hybrid IEM AK ZERO1. It has been exquisitely crafted with high-purity silver plating and copper, and the aluminium plugs give it even more class. The MMCXS connector provides the best quality, offering a long-lasting stable performance.
Design
AK ZERO1's premium sound will open a whole new world that you 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. "The Boundary to a New World" This key phrase encompasses the design of the AK ZERO1.
