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.
