NF Audio NE4 Evolution 4BA IEMs Released

by Wang Shuzeng on Aug 12, 2021

As a headphone brand that started from balanced armature units, NF Audio NA1 has brought a wonderful debut with brand-new technology, NA2+ and NM2+ have blossomed at the same time for ordinary music lovers and professional users, and have achieved good reputation and sales. Since NF Audio slowed down the update of the normal line-up products, and the development process of pure balanced armature earphones, they have began to focus on the new tuning technology and develoed a new structure and design to change the category of earphones: The NE4 Evolution.


This pair of high-resolution IEMs brings us a combination of four high-performance Knowles BA drivers producing a high-resolution crisp sound that complements different genres with its great clarity and detail. It also comes with three pairs of adjustable sound tuning with replaceable faceplates, which allows to change the frequency crossover between drivers in order to achieve different tuning profiles, NF Audio NE4 Evolution is available in our store for USD$ 749. 




Different from the common replacement filter and tuning switch in the market, NE4 can directly replace the crossover integrated on the panel, which can change the sound greatly. The frequency divider is the core tuning component of the multi-unit headset. Different circuit architectures and parameters enable different units to work at different frequencies with different power. 


NE4 adopts 4 BA units variable architecture, two high-frequency units are always responsible for the treble part, the other two are low and medium architecture in the Pop music mode, to improve the low frequency volume and texture, retain the original dynamics of the unit, the sound field is magnificent, majestic, and full surging sense of hearing. The reference faceplate is the full frequency + ultra-low architecture, and the transparent mode is both full frequency. The change from three-way frequency to two-way frequency, the traditional switching method can not do this. By the way, the red faceplate is for Pop music, grey one is reference tone and blue filter is for transparent sound.


NF Audio has crafted the ear cavities for NE4 Evolution using 5-axis CNC precision carving processes. The pair is lightweight and sturdy crafted in an ergonomic design to ensure a comfortable fit for its users. Enjoy countless hours of high-resolution music with the NE4 Evolution. They pack the pair with a 5N silver-plated oxygen-free copper cable with up to 280 cores. The cable shows low resistance to the audio signal.
