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 Dynamic Driver, two BA drivers, and a 5.6 mm Dynamic Driver, the AK ZERO1 harmonises 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. Lastly, the housing designed with Astell&Kern's unique advanced aluminium-refining technology keeps resonance to a minimum and creates the highest-quality sound.

Hi-Fi Grade Pure Silver-Coated OFC Cable 4 Core (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 aluminium plugs give it even more class. The MMCX connector provides the best quality, offering a long-lasting stable performance.
