what's the difference between 5-axis CNC engraving and die casting ？
Cost * Precision * Quality * Texture
Die casting: similar to injection molding, first melt the metal into liquid, and then use the mold cavity to apply high pressure to the molten metal to enter the mold to obtain the finished product.
5-axis CNC engraving: cutting, drilling and polishing the whole metal by 5-axis CNC machine tool, and finally obtaining the finished product.
Compared with die casting, 5-axis CNC engraving has higher cost, better precision, more stable quality and better texture. This process is usually used in aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries.
Acoustic Fidelity:
upgraded dual magnetic circuit, dual cavity and electric adjustable coil unit, with metal reflective cavity, the bandwidth is up to 9-40khz, the timbre is more stable, and the resolution is much better.
Material:
aviation aluminum 5-axis CNC engraving processing, more precise, higher strength, with one side only weighs 6.1g, more lightweight.
Wire:
Litz structure 5N oxygen free copper plating silver wire, core up to 280, lower impedance, lower skin effect and lower proximity effect.
Comfort:
“Real · Customize Design” with cymba conchae, more comfortable to wear.
Accessories:
6.35 to 3.5 adapter, balance cover * 6, low frequency cover * 6.
Package:
New gramophone record type packaging design, and standard configuration with exquisite storage bag.
Vocal Art NF Audio MC2L-10 II Moving Coil Unit
Integrated Tuning Circuit
Circuit tuning brings more possibilities for moving coil. MC2L-10 II adopts a higher precision integrated tuning PCB board, which is more stable and reliable, and has a better timbre.
Tesla Level Dual Magnetic Circuit
Magnetism is the power source of moving coil. MC2L-10 II unit adopts double magnetic circuit design. Two high-performance rare earth NdFeB magnets provide more than 1 Tesla of magnetic flux, thus providing greater driving force, higher sensitivity, and better dynamic and transient performance.
Dual Cavity Design
The traditional moving coil unit only has a rear cavity. On this basis, MC2L-10 II adds an additional rear cavity, which can control the air pressure more precisely, make the diaphragm move more smoothly, while the sound field is more grand and the sound details are more abundant.
5u High Polymer Composite Diaphragm
Different from the popular high rigid diaphragm in the market, MC2L-10 II adopts a kind of light, medium rigidity and good elasticity polymer composite diaphragm from the sound point of view. With the well-designed lines, it can get lower distortion and better performance of music.
Tuning Art Monitoring also Sweet-Sounding
Accuracy and pleasant hearing are two dimensions of sound. On the basis of understanding music, tuning determines whether the sound is accurate, and material determines whether the timbre is sweet-sounding.
4 groups of air pressure balance damping, can adjust the air pressure balance before and after the cavity. With circuit + physical tuning, the frequency response is straighter, the dynamic transient performance is more accurate, and the sound field restoration is more real. Accurately restore the drum, BASS line and harmony trend. Whether EQ, compression, reverberation, or the performance of yourself and partners on the stage, you can get high reference value.
The carefully designed interior acoustic structure, together with metal reflecting cavity, bring more delicate and stable sound performance, fuller intermediate frequency, more gorgeous high frequency, and interpret the emotion of music with elegant timbre.

Musicians, Understand Musicians Better
All monitoring is to restore the original appearance of music. On the basis of understanding music, the more refined the tuning, the more accurate the sound. Special means are adopted to increase the range of low frequency below 100Hz to better hear the drum, BASS line and harmony trend.
With circuit + physical tuning, the frequency response is straighter, the dynamic transient performance is more accurate, and the sound field restoration is more real. Whether EQ, compression, reverberation, or the performance of yourself and partners on the stage, you can get high reference value.
Wire Art: 0.78mm 2Pin
Official Transparent Silver Plated Line
The impedance, capacitive reactance and inductive reactance of earphone wire will have a significant impact on the sound. NM2 + is equipped with Litz structure 5N oxygen free copper plating silver wire as standard, with up to 280 cores, lower impedance, lower skin effect and lower proximity effect, which makes the sound more detailed, the sound field more open, and the timbre more relaxed.
Little Blue Dot, True Love of Everyone
The special Blue Dot LOGO gives NM2 + a different flavor. Based on years of experience in the manufacture of customized earphones, NF Audio NM2 + is created according to human ear model, which has elegant aesthetic appearance and outstanding acoustic performance, also is more comfortable to wear. Wearing around the ear, the activity on the stage is more free, convenient and not easy to fall off.
At the same time, the panel draws lessons from the design language of guitar pick, and conveys the music creation feelings of NF Audio brand in simple and generous ways.
Responsible for Ears
The sunken for crus of helix, the raised for cymba conchae, the notch between the tragus, the angle of the ear canal, and the big inside and small outside of the inner concha cavity, every tiny detail is for a better listening experience.
Art of Ingenuity
Brilliant Craftsmanship, Hidden Creativity
Produced by Engineers with Over 10+ Years’ Experience
300+ Wearing Tests and Adjustment
In the era of productive forces, we have become "exotic" artists.
Engineers with more than 10 years of experience, sculpture level modeling, more than 300 times of wearing tests, all are for bringing better wearing experiences. Every detail is the place of ingenuity, which also contains excellent taste and infinite possibilities.
Variable Size, Same Sound Quality
NA2 is equipped with soft and elastic silicone earplugs in three sizes. Choosing the right silicone earplug to fit your ear shape, so that the NA2 will not cause discomfort in the ear.
Female users have smaller ears than men. They can choose small or medium silicone earplugs to match, which is closer to the ear shape and more beautiful. At the same time, the balanced cover and the low-frequency cover have two different timbre, which can be freely selected according to your preference to get better listening feeling.
25db Passive Noise Reduction
Noisy environment, in addition to annoying people, will unconsciously make people turn up the volume and damage their hearing ability. Scientific research shows that only when the music volume is 20 dB higher than the ambient volume, can people hear the details of the music clearly. NA2 provides a passive noise reduction effect of up to 25dB, changing the downtown into a bedroom and making the noise be quiet. Make the place you are in becomes your exclusive stage.
Round Exquisite Storage Box
Beloved earphones need careful care, a beautiful, pressure resistant storage box is essential. NF Audio round storage box, high quality canvas + high strength EVA lining, not only provides excellent feeling, but also gives excellent protection.
