Electrostatic Drive Units and Dynamic Unit In-Ear Earphone Wired Headset Detachable Cable for C12 C10

Description:
CCA electrostatic unit Specifications: description:
1. The size is 6.8mm diameter circle. 
2. The sounding principle is a sounding unit designed based on the reverse principle of electret wheat in the wind. It can also be called an electret electrostatic unit. Static electricity is mainly charged by the diaphragm, so it is called static electricity. 
3. It belongs to the low-voltage driving sound unit. 
4. Compared with the traditional high-voltage electrostatic unit, our electrostatic unit is easier to drive, the weak point is the non-full frequency output. 

Feature:
Advantages of electrostatic unit:
1. The distortion rate is lower than the moving iron unit. 
2. High sound density, strong ability to restore details. 
3. The high frequency sensitivity in the frequency response range of 20KHZ is higher than that of moving iron at the same frequency. 
4. Acoustic phase is stable, easy to expand the high frequency matrix. 
5. Quality consistency is better than moving coil and moving iron.
