Tech Behind:-

Most of the earphones in the market use tuning nozzles to adjust the sound tuning, the NE4 Evolution adopts a revolutionary new way to switch the tuning to one's favor. The frequency divider or frequency crossovers are the core tuning component of multi-driver earphones. Different circuit architectures and parameters enable the driver units to work at different frequencies with different powers and an option to adjust them can bring drastic changes to the sound tuning. NE4 brings the user a way to adjust this crossover with the four drivers with replaceable faceplates.

High-Performance Knowles BA Drivers:-

NF Audio has trusted the widely known Knowles Balanced Armature drivers for their latest earphones. NE4 Evolution has a combination of Knowles 22955+29689+31736(Composite) drivers covering a wide frequency band. NE4 Evolution produces a high-quality sound with great clarity and detail. With different frequency-dividing faceplates, the pair is all ready for different genres of music.

Different Faceplates For Different Crossovers:-

NF Audio NE4 Evolution comes packed with three sets of different face covers, Red, Black, and Blue. All three of these offers changes in the frequency crossover for the drivers in the pair. Red face cover is for Pop music where bass extensions are required to make the output fun and lively. It adopts a three-way frequency division with one BA unit for low, one BA unit for mids and two BA units for high-frequencies. Similarly the Black faceplates for reference sound with a three-way architecture with one BA for ultra-lows, one BA for a full-frequency response, and two BA for high-frequencies. The third Blue filter is for transparent sound with a two-way architecture, one driver for full-frequency response and two for high-frequency drivers. This third filter utilizes only three drivers with the pair. The connectors on the faceplates are sturdy and have a solid build with gold-plating for firm connection.
