Hi-Fi should not be defined by price
KZ EDCX is intended to correct two hot and almost useless product gimmicks in the Hi-Fi circle, which some so-called well-known brands respect.

To popularize real earphone tuning
It alludes to two selling points that are almost useless or deviate from the original design principles of earphones, which are recognized by the so-called high-end brands and high-end products in the circle and are vigorously promoted by the so-called professional public KOL.

Seiko design with great beauty

A transparent PC cavity embedded with highly reflective stainless steel trim gives KZ EDCX a diamond-like sparkle.

A controversial 10mm dynamic driver

Instead of using the so-called fancy diaphragm material, we used the most common 6 microns thick PET diaphragm into the driver on KZ EDCX. At the same time, we use four layers of the voice coil to enhance its output performance. Additionally, we by adjusting the height of the voice coil to accurately adjust the location of the high-frequency formant, by adjusting the damping to control the sensitivity of low frequency, by adjusting the size of the driver's cover aperture to control the height of the ultra-high frequency formant, by compressing the volume of the internal space of the driver to control the position of the 2-3 kHz formant and assist in controlling the position of the ultra-high frequency formant. We finally completed this driver through the above technical adjustment and compared similar products' FR curves and distortion data to ensure that KZ EDCX can compete with those high-priced and so-called professional Hi-Fi dynamic lEMs.

KZ EDCX has the same U-shaped tuning as those high-end products

U-shaped curve tuning is a tuning style recognized by many Hi-Fi enthusiasts in recent years, and its main feature is that it tends to follow the Harman curve. The tuning of the KZ EDCX is also adjusted in this direction. U-shaped tuning style can consider both low frequency and high frequency, highlighting the separation between the three frequencies, so the low-frequency performance will maintain clarity even if the volume is increased. In this style, there is a difference of about 10dB between high frequency and medium frequency in sensitivity so that we can feel a high separation between vocals and instrumental music.
