Astell & Kern AK ZERO2 Advanced Quad-Brid In-Ear Monitors

Enjoy premium sound reproduction with the Astell & Kern AK ZERO2, a pair of advanced Quad-brid in-ear monitors that's build off the success of the original ZERO1 IEMs. Several enhancements have been added, including an ultra-refined crossover network design and acoustic chamber that perfectly harmonizes the four integrated driver types.

The AK ZERO2 features four drivers including a micro rectangular planar dynamic driver, two dual custom balanced armature drivers, and a 10mm dynamic driver with a piezoelectric transducer, which combine in a 3D printed acoustic chamber. The outer enclosure is crafted from a precision CNC-machined aluminum housing, which limits resonance to create a stable, high-quality sound. The ZERO2 includes two cables (4.4mm TRRRS and 3.5mm TRS) made from Hi-Fi-grade pure silver-coated OFC. A set of five silicone eartips, a pair of foam eartips, and a travel case are included.

Advanced Quad-brid Design

Special Micro Rectangular Planar Dynamic Driver

• High crisp and dynamic treble sound
• The micro rectangular planar dynamic driver is 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. A&K 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 ultralow 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 10mm 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 10mm 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 Crossover Network

The ultrarefined crossover network enables a perfect balance between six drivers with distinctive sound characteristics, maximizing each of their acoustic traits while creating a balanced harmonized sound.

3D Printed Acoustic Chamber

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 A&K's state of the art facilities in Japan to offer you the highest quality through strictly managed processes.
