NF Audio NE4
NF AUDIO NE4 Evolution 4BA Replaceable Frequency Dividing Faceplate 2Pin 0.78mm HiFi Audiophile In-Ear Earphone
The changes beyond your expectations, the possibilities of countless voices
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.
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 circuit structure, electrical parameters, and types of resistance-capacitance components can be changed, and the range of sound changes is huge. At the same time, under different circuit architectures, NE4 Evolution can be not only 4 drivers, but also 3 drivers, 2 drivers or even single driver. It only needs to replace the faceplate to get a completely different sound
Classic and conflicting timbre standard is at your fingertips
Sound is the art of balance. Generally, it is impossible to achieve popular, balanced, positive, and transparent and beautiful in the same earphone.Switch
tuning,based on a specific circuit, some parameters are adjusted, and the range of change is limited.However, the NE4 Evolution can obtain the above
three sound at the same time by replacing the three
standard frequency dividing faceplates, and this is just the
Pop faceplate (red)
Pop music needs full low frequency and abundant dynamics. The pop faceplate adopts the classic low + mid + 2 high frequency three-way architecture design to improve the low frequency volume and texture, retaining the original dynamics of the driver, the sound field is magnificent, majestic, and full Surging sense of hearing.
Reference faceplate (black)
A balanced sound requires restraint and control. The reference faceplate adopts a three-way architecture design of ultra-low + full frequency + 2 high frequency, which controls the energy distribution of the full frequency band to the right degree, and accurately controls the dynamics of the overall sound, the sound is calm, clean, and reference sound.
Transparent faceplate (blue)
In order to keep the sound transparent and clean, the transparent faceplate uses the full frequency + 2 high frequency two-way architecture design, the full frequency driver maintains the integrity of the music, and the two high frequency drivers provide excellent high frequency response and ductility, sound gorgeous, and moving.
One buckle and one twist, change has never been easier
For commodities, ease of operation is very important. The NE4 Evolution faceplate and frequency divider are combined into one. Only screws can be used to replace the faceplate and sound at the same time. Whether it is the standard faceplate or the follow-up special tuning faceplate, is the same simple operation, very different sound.
Classic American Knowles 4 balanced armature, good raw materials, good taste
The driver is the base of the sound, and the driver is good enough to get a better sense of hearing. NE4 Evolution adopts the classic four-driver combination of Knowles 22955 + 29689 + 31736 (composite driver), with full cover of low frequency, intermediate frequency and high frequency. With high-quality sound bottom and different frequency dividing faceplates, every sound can stand the test.
Exquisite products, the soul of evolution. 5-axis CNC precision-carved shell aluminum, stainless steel precision art
Metal not only has a super texture, but also a long service life. CNC precision carving is a pearl of precision metal processing technology. NE4 Evolution adopts 5-axis CNC precision carving to process a whole piece of aviation aluminum ingot and stainless steel, achieving a good balance in weight and strength. Only exquisite products and evolving souls can exchange for long-term company.
What you care about, we care more. Stable and reliable connection, gold-plated layer up to 10μ, life test 100,000 times
The frequency divider is replaceable, and the connection between the driver and the frequency divider is the top priority. The driver end adopts military-grade spring probes, which has lower distributed capacitance and inductance. The gold-plated layer is as high as 10μ and has passed the life test of 100,000 times. The frequency divider adopts PCB pad + copper pillar design, which is stable. The stability and reliability of the connection are as important as innovation, and all the details are for a more excellent user experience.
Small investment, big change, the sound exploration
For NE4 Evolution, the core value lies in continuous sound evolution. We will launch official frequency dividing faceplates one after another to suit different music styles and usage scenarios.
In the near future, the official will also launch a DIY kit and provide official tutorials. Friends with hands-on ability can create their own exclusive sounds.
We hope to use NE4 Evolution as the medium to create a complete frequency dividing faceplate ecosystem. Let every mood be placed somewhere and have a sound to follow. Let every love be unswerving and go all out.
2pin 0.78mm transparent silver-plated cable
The impedance, capacitive reactance and inductive reactance of the earphone cable will have a significant impact on the sound. NE4 Evolution comes standard with Litz structure 5N oxygen-free copper silver-plated cable, with up to 280 cores, lower impedance, lower skin effect and proximity effect, making the sound details more, the sound field is open, and the tone is relax.
Every tiny detail is for a more hearty listening experience
The ergonomics of in-ear earphones is equally important. The proportions and contour lines of the NE4 Evolution condense the profound skills NF Audio has accumulated in the field of custom earphones over the years. The sunken of the helix angle, the bulge of the cymba, the notch between the tragus and the angle of ear canal, the large and small shapes inside and outside the concha cavity, every tiny detail is for a more hearty listening experience.
Romantic gifts from hardcore brands
In life, the sense of ritual is very important. The beautiful packaging box and the right accessories make the hard core also have a unique romantic beauty.
