Astell&Kern AK Zero2
The Astell&Kern AK Zero2 are designed and built by Astell&Kern and hand-built by experts in Japan!
The AK ZERO2, a stunning pair of Quad driver in-ear monitors (IEM) that redefine precision design and performance at this level.
Handcrafted in Japan and clad in Astell&Kern’s signature angled aluminium, the AK ZERO2 earphones combine 4 different types of driver technology to optimise audio performance across all sound frequencies. Exceptional cross-over network management means the different designs work together in perfect harmony.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
Those drivers in more detail
The AK ZERO2’s micro rectangular Planar Dynamic Driver has been specifically developed to deliver high frequencies, using advanced technology to optimise the planar design for in-ear use.
The IEMs also feature four custom-made Coil Parameter Dual Custom BA Drivers to reproduce both full range and mid-to-low range frequencies. This ultra-low distortion design is ideal to deliver outstanding clear vocal performance, along with perfect harmonisation across all frequencies.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.
