Features
Possibilities of Countless Sound Styles
NE4 Evolution uses sophisticated engineering design to place the frequency divider externally. By simply replacing the frequency divider faceplate, it can provide unlimited upgrade space for earphones without repeated consumption.
3 Standard Tuning Faceplates
Sound is the art of balance. Usually, in the same earphone, it is impossible to be not only suitable for fashion, but also balanced and beautiful. By replacing the three standard frequency division faceplates (POP, Reference, Transparent), you can obtain the above three sounds at the same time.
Simple Switch by One Screw
For products, easy operation is very important. For NE4 Evolution, the faceplate and frequency divider are combined into one. The faceplate and sound can be replaced at the same time with only one screw. Hex Key & Spare screws are all preapred.
4 Knowles Balance Armatures
The drivers are the foundation of the sound. NE4 Evolution uses Knowles 22955+29689+31736 (composite driver), classical four-unit combination to cover full frequency range. High-quality sound with different crossover panels.
5-Axis CNC Technology
NE4 Evolution adopts 5-axis CNC precision carving to process the whole aviation aluminum ingot and stainless steel, achieving a good balance in weight and strength.
Reliable Connection
For interchangeable frequency divider, the connection between the driver and the frequency divider is the top priority. The driver end adopts military grade spring probe, with lower distributed capacitance and inductance. The gold plating layer is up to 10u and passes 10W life tests. The frequency divider adopts PCB Pad + copper column design, which is more stable.
