A Controversial 10mm Dynamic Driver

KZ EDCX used the most common 6 microns thick PET diaphragm into the driver on EDCX. At the same time, it use four layers of voice coil to enhance the output performance. Additionally, by adjusting the height of the voice coil to accurately adjust the location of high-frequency formant, by adjusting the damping to control the sensitivity of low frequency, by adjusting 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 2-3K Hz formant and assist in controlling the position of the ultra-high frequency formant. Through the above technical adjustment, KZ completed this driver and compared the FR curve and distortion data of similar products to ensure that EDCX can compete with those high-priced IEMs.

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

U-shaped curve tuning is a tuning style recognized by many HiFi enthusiasts in recent years, and its main features that it tends to follow the Harman curve. The tuning of the EDCX is also adjusted in this direction. U-shaped tuning style can take into account both low frequency and high frequency, highlighting the separation between the three frequencies, so the low frequency performance will not lose clarity even if the volume is high. In this style, there is a difference of about 10dB between high frequency and medium frequency in sensitivity, so we can feel a high separation between vocals and instrumental music.
