Description CCA electrostatic unit specification description 1 The size is 6 8mm diameter circle2 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 unit4 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 unit2 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 matrix5 Quality consistency is better than moving coil and moving iron Specification Brand CCAModel NRAHeadphone type in earImpedance 25Ω±10 Headphone sensitivity 103db±3dbFrequency response range 20Hz 40KHzPlug type 3 5mm straightCable length 1 2mColor CyanWith line YesHeadphone interface 2pin interfaceIf with microphone no microphone with microphoneCan spare cables YesDrive unit 1 electrostatic drive unit 1 3 dynamic magnetic driveProduct size 28 25 14mm 1 1 0 98 1 55inProduct weight 30gPacking size 105 90 40mm 4 13 3 54 1 57inPackage weight 130gPackage I
