Any mention of "us," "we," "our," etc is by Astell&Kern, not AV One.
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 harmonise the four different drivers that power the AK ZERO2, designed to play the true sounds of Astell&Kern.
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.
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 minimise 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 harmonise each frequency range, playing perfect sounds.
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.
Super-Low-Noise Cross-Over Network
The ultra-refined cross-over network enables a perfect balance between six drivers with distinctive sound characteristics, maximising each of their acoustic traits while creating a balanced harmonised 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 aluminium processing technology, limits resonance to create stable high-quality sound.
The pure silver-coated OFC cable, designed to maximise 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 aluminium.
The MMCX connectors offers a robust connection and a long-lasting and stable life cycle.
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.
