Product Description
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.
- 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
The AK ZERO2 is an IEM that features a “Quad-brid” design centered around an advanced driver array and Super Low Noise Cross-Over Network perfectly tuned. Four different types of driver, including Custom BA Drivers, a Planar Dynamic Driver, a 10-mm Dynamic Driver, and a Piezoelectric Transducer create the perfect synergy, coming together to form the Quad-brid AK ZERO2 capable of reproducing the pure sounds that Astell&Kern strives to deliver.
Advanced Quad-brid Design
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.
- [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.
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.
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.
