Amazing 16-unit hybrid configuration KZ-ZAX is a hybrid earphone equipped with a total of 16 driver units on the left and right sides. It uses one dual magnetic circuit dynamics unit and seven balanced armature units to create a clear and immersive sound field from low to ultra-high frequencies. It reproduces every detail of the music. Overwhelming bass and expressiveness The 10mm PEK spring membrane of the dynamic range unit reproduces deep bass with a powerful magnetic drive. Meanwhile, the combination of two 30019 closed BAs and four 50024s faithfully reproduces the nuances of mid-range vocals and melodies. It gives music a rich expression. Glittering metal finish & premium cable The shiny pearl chrome-plated metal housing creates a luxurious feel. The standard high-purity oxygen-free copper silver-plated cable (4-core x 25-core) suppresses external noise and provides clear sound quality. It aims to achieve both an elegant appearance and a high-quality sound design. Detachable 2-PIN design & high wearability The 2-PIN connection allows cable replacement. Sound tuning and wireless use are possible by using re-cabling. In addition, the ergonomic smooth cavity design fits gently deep into the ear, making it less tiring to wear for long periods of time and effectively blocking external noise. Built-in dual electret microphones for calls Equipped with dual condenser microphones for high-quality calls. You can make calls and video conferences on your smartphone or PC with clear audio. Operations such as play/pause, forward/backward, answer/end calls, and reject calls can be intuitively operated with a single button.
