Revolutionary New Technology To Change The Frequency Crossover:
In multi-driver earphones, the sound tuning is heavily dependent on the frequency crossover arrangement. It decides which driver will perform for what frequencies, and helps the engineers tune the output accordingly. NE4 brings a revolutionary new feature to switch the frequency arrangements with different sets of facepanels. Most of the earphones in the market have replaceable tuning nozzles, experience a drastic change with the advanced frequency crossover switching option on the NE4 Evolution.

NE4 Evolution has three different sets of replaceable face covers bundled in the package. The Red face panel enhances the lower-end response and brings a punchy presentation that complements EDM, Pop, and similar genres. 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.
