NF Audio NE4 Evolution
4BA Replaceable Frequency Dividing Faceplate 2Pin 0.78mm HiFi Audiophile In-Ear Monitor
NE4 Evolution, with the exquisite engineering design, the frequency divider is external, and only by simply replacing the frequency dividing faceplate, it can provide unlimited upgrade space for the earphones, without repeated consumption, one = innumerable.
The frequency divider is the core tuning component of the multi-driver earphones. Different circuit architectures and parameters enable different drivers to work at different frequencies with different powers. The same driver, coupled with different circuit architectures, parameters, and frequency dividers of resistance-capacitance components, can obtain a completely different sense of hearing, which is also the top priority of multi-driver earphone tuning.
