Description

Special Micro Rectangular Planar Dynamic Driver

The Micro Rectangular Planar Dynamic Driver is a driver specifically developed to deliver high frequencies, featuring advanced technology that allows a planar driver to be used in IEMs, despite the extreme difficulty in making it small enough to fit in such a small cavity.
We selected a light yet sturdy planar membrane to minimize frequency loss and applied a trembler with a thin metal membrane and polymer film to create lifelike vivid high frequencies. This provides a clear and dynamic high frequency response.

Dual Custom Balanced Armature Drivers

The Micro Rectangular Planar Dynamic Driver is a driver specifically developed to deliver high frequencies, featuring advanced technology that allows a planar driver to be used in IEMs, despite the extreme difficulty in making it small enough to fit in such a small cavity.
We selected a light yet sturdy planar membrane to minimize frequency loss and applied a trembler with a thin metal membrane and polymer film to create lifelike vivid high frequencies. This provides a clear and dynamic high frequency response.

Single 10-mm Dynamic Driver with Piezoelectric Transducer

Various types of carefully designed drivers create rich, Hi-Fi sounds. The 10-mm dynamic driver used in the AK ZERO2 is meticulously manufactured using a fully automated process. This allows the driver to recreate rich and deep low frequencies.
An additional piezoelectric transducer works in tandem with the dynamic driver, serving as a super tweeter that asserts its presence in the super-high frequency range that many IEMs struggle to recreate.

Super-Low-Noise Cross-Over Network

The ultra-refined cross-over network enables a perfect balance between six drivers with distinctive sound characteristics, maximizing each of their acoustic traits while creating a balanced harmonized sound.

Each Driver Has an Acoustic Chamber Made Using 3D Printing Technology

Each driver is placed optimally in an acoustic chamber that is created through refined 3D printing technology. This design eliminates any unnecessary movement and resonance of the drivers for permanently stable performance.

 
Precise CNC Housing

The housing, which is made using Astell&Kern's advanced aluminum processing technology, limits resonance to create stable high-quality sound.

Hi-Fi Grade Pure Silver-Coated OFC Cable 4 Core

The pure silver-coated OFC cable, designed to maximize the performance of the AK ZERO2, is created with high-purity silver plating and copper, and adds a touch of style with plugs crafted from aluminum.
