Astell&Kern professional IEM AK Zero 2 In-ear Headphones

    Description

    Advanced Quad-brid IEM

    Astell&Kern's philosophy of striving to deliver ultra-precise original sounds has been praised by many audiophiles from the result of our first IEM, the AK ZERO1.

    The AK ZERO2 is a professional IEM made using advanced technologies based on our experience gained from the development of the AK ZERO1.

    The ultra-refined cross-over network design and acoustic chamber perfectly harmonize the four different drivers that power the AK ZERO2, designed to play the true sounds of Astell&Kern.

    Features

    • Four different types of drivers
    • Perfectly harmonized driver structure
    • Highest Cross-Over Network Management
    • Acoustic Chamber by 3D Print Technology
    • Precise CNC Metal Housing
    • Hi-Fi Grade Pure Silver-Coated OFC Cable
    • Made in Japan

    Advanced Quad-brid Design and Ultra-refined Cross-over Network

    The AK ZERO2 IEM is engineered with a specialized "Quad-brid" architecture, encompassing an optimized driver array and the Super Low Noise Cross-Over Network for precision tuning. Custom BA Drivers, a Planar Dynamic Driver, 10-mm Dynamic Driver, and a Piezoelectric Transducer work in synergy to deliver a pure sound experience, as intended by Astell&Kern.

    Advanced Quad-brid Design

    Special Micro Rectangular Planar Dynamic Driver

    - [High] Crisp and Dynamic Treble Sound

    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

    - [Mid-Low] Transparent Vocal sound
    - [Full Range] Perfectly Balanced and Rich Sound

    The Coil Parameter Dual Custom BA Driver is a custom-made driver designed to reproduce both full-range and mid- to low-range frequencies.

    It comes with a total of four drivers: two BA drivers that offer ultra-low distortion to create clear low- to mid-ranged vocal sounds and two BA drivers that offer perfectly balanced rich sounds, uniquely tuned to harmonize each frequency range, playing perfect sounds.

    Single 10-mm Dynamic Driver with Piezoelectric Transducer
    Single 10-mm Dynamic Driver with Piezoelectric Transducer
    - [Low & Super High] The Deepest Bass and Clear Treble Sound

    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.

    Ultra-refined Architecture Design

    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.

    The MMCX connectors offers a robust connection and a long-lasting and stable life cycle.

    Made in Japan

    Each AK ZERO2 is meticulously assembled by professional technicians with extensive experience and is produced at our state of the art facilities
    in Japan to offer you the highest quality through strictly managed processes.
