Speaking of “national standards†(custom made domestic headsets), it can be said that these years are alive and well. The major brands can be described as flourishing, and among them, NF AUDIO is a rather special brand, paying attention to the tuning of Zhongzheng and the “strength of combatâ€. The very high founder "Old Sheep" is undoubtedly a brand feature. And I recently received the first batch (if no accident should be the first, of course, still a low-key man or alive) of the private film NF6 headphones, taking advantage of this opportunity to share with you about this new product.
The following share based on the private mode NF6 retail version, and the audition public version of the sound will be slightly different, in addition to grab the headset itself did not go through enough downtime, the sense of hearing is for reference only. Â
Since it is a starter, of course, it is necessary to write a running account, before we write a sense of hearing we first come to understand this so-called "portable ceiling" headset some basic information:
NF AUDIO NF6
Unit configuration: six balanced armature units (which we commonly call moving iron)
Frequency division: 4 frequency divisions (9 components)
Sensitivity: 106dB@1kHz
Impedance: 18Ω @ 1kHz
Frequency response range: 8-30kHz
Distortion: <0.5%
Soundproof: 26dB
From the point of view of parameters, NF6 does not seem to be very special, and the number of units can only be said to be medium according to the current popular routine (after all, many brands of units have double digits), which is considered low sensitivity and high sensitivity in terms of sensitivity and impedance. A headphone (but it is not very good push, as mentioned below). The most special is that the NF6 uses three moving iron units at a time, including the well-known BK series and ED series units of Knowles, the Sonion 3300 series units (composite units), and the joint development of NF AUDIO and Double Acoustics. The moving iron unit (composite high-frequency unit).
Of course, I will not be willing to demolition their own headphones, here on an official shooting NF AUDIO independent research and development unit of the United States and it. Some people have read that this unit is only a "marking", but according to the author's understanding (the author has the privilege of participating in the press conference of the Double Sound mobile unit), when he cooperates with the manufacturers, he will make special arrangements according to the needs of specific manufacturers. The development, and NF AUDIO this unit and the deep sound of the product of cooperation, it in some indicators and materials and other times the sound of other moving iron units are different.
The old sheep in the development of this headset is a great time in the frequency division, NF6's internal even directly plug an area of ​​exaggerated circuit board to do the crossover, which is NF6's publicity "9 crossover components The origin of Although the material is sufficient, the number of frequency divisions is not astonishing. There are low, medium, high and high four-way frequency divisions. From the perspective of this crossover architecture, NF6 does not enhance the sense of low frequency with the big stream. We know that many multi-frequency-divide headphones will have extremely low-frequency and low-frequency two-way frequency division, and NF6 seems to intentionally enhance high frequencies from this aspect. Aspects of processing. PS: I still look forward to domestic appearance of a unit like SE5WAY corresponding to a crossover headset, think about the “555†monster combination of 5 units and 5 channels and 5 channels, which sounds especially domineering. However, it is estimated that this process will encounter a lot of trouble, only YY about the future of the old sheep out of a NF6 Plus, using the "666" configuration.
NF6 map reward
Since it is a custom earphone, the overall appearance is very close (after all, according to the earmarks), but the material, the length of the catheter, the color, the panel design, and the cavity size of each home are all very different, and also create a variety of Custom headphones.
NF6 still comes with a Pelican 1010 waterproof storage box, the market price of the box is about 100 yuan.
The author's custom NF6 in Artwork's choice is not very complicated, but it should also be able to fully reflect the "custom" style, the left side of the transparent purple cavity + brushed blue panel + personal signature logo, the right is a transparent green cavity + Wood grain panel + NF brand logo.
The effect is basically in line with expectations, but the color seems to be a bit too "dark", the details of the right panel is not easy to see, this is the fly in the ointment.
The author's NF6 is the first one of the first, so the number is also very special, is NF6000, the number will be prefixed with the user's name in front, but this lettering is only one of them, engraved on the top of the headset.
The NF6 uses a rigid die design, and the catheter is not very deep, probably just to the "second bend" position.
The sound guide hole is also a continuation of the characteristics of the NF series, using an all-in-one structure, it is said that this design can increase the sound field, of course, the disadvantage is also very obvious, that is easy to make dirty things fall into the hole. A similar design is actually rare. In mainstream products, only two brands, VE (Vision Ears) and Rhines from Germany, use similar sound hole settings.
Like most customizations, the NF6 also uses a line-changeable design. It also uses the mainstream 0.78mm dual pin. The need for Tucao is that the phase of the NF AUDIO is actually the opposite of other headphones that use a 0.78mm signal. While other headphones are on top. If you are holding a large number of local-grade upgrade lines, you should pay special attention to it. When you order your NF headset, you must specify this point. With the + pole set to the top, you can be perfectly compatible with the existing upgrade line. Although theoretically speaking, the opposite sides of the left and right sides will not cause great sound changes, but this is not awkward psychologically.
Sound performance
A headset, of course, is the basis for the sound, NF6 as the first multi-unit high-end headphones NF AUDIO, in terms of sound performance also received much attention. After audition activities in Guangzhou, Beijing and other places, many enthusiasts shared their own listening experience with the NF6 male model, and most players still gave a very positive evaluation. However, there are also some who think that NF6 is extremely difficult to push. After pushing it out, it can even win with Beyerdynamic T1. It seems that everyone's views are still quite different.
Let's talk about listening equipment first
Headphones: NF6, NF4, VE6 X1 (In order to be fair, use the original wire of NF AUDIO.)
Front-end: iPhone 7 Plus, fly proud X7 + AM3 balance module
Desktop: PC+Benchmark DAC2L+BHA-1
Music: omnivorous, vocal-based, of course, the song itself is certainly enough for "Hi-Res."
Push to hear
Since NF6 is indeed more "eating current," it is not surprising that it does not exert its strength on direct pushing. Therefore, this time, the sense of hearing is divided into two situations: direct promotion and taking office. From the parameters point of view, NF6 is a high-sensitivity low-impedance headphones, but in fact it is not a good push.
The first is the iPhone 7 Plus, which is a popular mobile phone and has played a role in the mobile phone in all aspects. Unfortunately, in the audio aspect, Apple brought a bad head this time and even removed the 3.5mm interface. This is a disastrous decision for us who like to listen to songs. Although Apple is very "well-intentioned" with a Lightning to 3.5mm adapter, but the tail when listening to songs, when you want to listen to songs can not be charged, are full of embarrassing things.
In terms of sound quality, the iPhone 7 Plus and its predecessors are slightly better than their predecessors (but the gap is small). There is a Codec model number 338S00140 in the Lightning 3.5mm adapter. iPhone 7 Plus connected to NF6, the first ear did not say completely impossible to listen, the basic direction of the sound is still able to hear one or two, the quality of the product compared to the previous (here to NF4, for example, after all, their private film, Listened for a long time, but it is estimated that NF3 and NF3Bass are the main forces. There is a noticeable improvement. As the number of units goes up, the sound density also has an audible improvement. But can feel the sound is not open, high and low frequencies have not played out, the sound field is also a bit narrow, the sound is balanced slightly more bright sound, but always gives a four-cylinder BMW X6 powerlessness, can see NF6 still has a lot of strength to use.
Switch to the X7 with AM3, there is no balance port, even if the 3.5mm port has significantly improved compared to the iPhone 7 Plus. In terms of thrust, AM3 has basically met the "rigorous" requirements of NF6. AM3 is not a fuel-efficient lamp and can reach output power of 170mW (32Ω) or more under unbalanced ports. Mobile phones like iPhones are generally poor. 20mW or so. In terms of “loudnessâ€, here is also a reference, X7+AM3 adjusts the high gain, use 3.5mm mouth, NF4 needs more than 40 volume will have a more appropriate sound pressure, and NF6 requires more than 50, from “Push a ring From an angle of view, NF6 is significantly more difficult than NF4. At this time, the evaluation of NF6's hearing should be relatively instructive. After all, most fans should use this grade or worse than the front end of this grade. First of all, the definition of NF6 is a very balanced sound style headset. Compared to NF4's balanced medium-high frequency, NF6's adaptability will be more extensive, because it's low frequency is obviously more solid, regardless of the low-frequency sense of volume or texture All are better. With the increase in the number of units, the NF6 has a significant and significant improvement in the resolution and sound density of the sound. In terms of specific tri-band frequencies, the low-frequency dive has been strengthened, and the sound field has clearly become larger. The amount of low-frequency can not be said to be surging, but it can be considered as a fist to meat. I believe there is no need for a "NF6Bass". In terms of mid-frequency, the thickness increases and becomes more stable. Relatively speaking, NF6 will be more suitable for the interpretation of male voices. NF4 will appear thinner and more elegant and more suitable for female voices. Of course, here is just talk about "fitness", sound quality is not a level of competition. IF details, density, are also better than NF6. In terms of high frequencies, the connection of NF6 in the high- and medium-frequency areas will be more smooth, and the extremity in extreme high frequencies will be better than NF4. In terms of high frequencies, NF6 has done quite well. This should be due to autonomy. Developed high-frequency composite units and processing on frequency division.
Next is the highlight, and the PK of VE6. VE6 is a controversial flagship custom headset. One of the reasons for the analysis may be that the male model does not play well on the sound. The other may be that some batches have a lot of quality problems and “dragging events†lead to its “people. Hope" is lower. The author's VE6 should belong to an earlier batch. Fortunately, there is no problem with workmanship and quality, and there is no part of the audiophile's low-frequency disability. It is worth noting that the contrast here is VE6 X1, which is a relatively low-frequency, relatively high-frequency and transparent version of the restraint. First of all, from the point of view of information quality and quality, VE6 is already closer to NF6, and there will be no obvious difference in quality between VE6 and NF4. From the direct push of X7, the overall control of VE6 is still better than NF6. After all, VE6 still has a more "optimized" aspect in terms of direct push. In terms of high frequencies, the superior high frequency extension and smoothness of NF6 in the home comparison is already at a disadvantage in comparison with VE6, and it is estimated that the gap will be even larger if the VE6 X2 is changed. In terms of midrange, the VE6's vocals should be more philosophical, and the analysis should be even better. The NF6's IF is relatively thicker than the VE6, and it is relatively less "irony". In terms of low frequencies, the NF6's low-frequency feel is obviously a little bigger, but the dive and texture are still worse than VE6. Directly pushing this link, there is still a gap between the two, after all, NF6 is not so good to wait, in addition VE6 is full of opportunity, and NF6 does not, such results are also expected.
Taiwanese sense of hearing
It has long been heard that the NF6 will burst out of endless potential on the Taiwanese aircraft. Here, a BHA-1 with enough "strong" is also used as an amp for audition. Sure enough, as the saying goes, there is a miracle, NF6 in a so violent amp (32Ω up to 2.9W output power) wait, it really became obedient. This is what all of them have: Resolving power, sound field, looseness, sound dynamics have all been explosively promoted, which made me wonder at a time when the old sheep was using a desktop amp when tuning. NF6 on the table, it seems to open up the Rendu second pulse, compared to the country's direct push tri-band appears crowded in a ball. What is most surprising is that the overall voice has not been greatly improved on the three-band, and it has no feeling of pushing over it. In the high-frequency area, the ductility is further improved. The sound field is two-fold larger, and the performance of the vertical sound field is indeed surprising. The texture, resolution, and transparency of the midrange haven't picked any stabs in this price plug. In the low-frequency area, the problem of insufficient dive and texture in the direct push of the national brick has ceased to exist. In exchange for a low-frequency performance with good atmosphere and excellent quality, of course, it should be said that the looseness, smoothness and big ears There is still an ear gap. At this point the NF6 has enough emboldened to face VE6, although the latter has improved after the arrival of the aircraft, but compared to the former's leap is still a little smaller. The comparison of NF6 and VE6 under the table can basically be regarded as similar in quality. Of course, the sound style of the two is still not a small difference. In the mid-high frequency, the convergence of VE6 will be more natural, and the amount of high-frequency information will be more, but the gap is not large. IF NF6 has a reduced thickness compared to direct push, but it is still a little thicker than VE6. The sound density of the two is close, NF6 is more straightforward, VE6 will be more emotional, and IF resolution VE6 is slightly dominant. The low-frequency sense NF6 is much more converging than the direct push, but the low frequency is still slightly more than the VE6. For some low-frequency controls, the NF6 on the table may have the problem of “not enoughâ€, and the VE6 is defined as “low-frequency disabledâ€. It is not surprising. To sum up, the NF6 already had the strength to call VE6 after it was on the desk.
to sum up
As a custom headset, this should be a Walkman or even mobile phone service, but from the perspective of NF6, it seems that it is a strong case of strong products. From the mobile phone → Walkman → Taiwan machine three-step upgrade point of view, NF6 is the obvious difference and the tri-band has a significant increase in a headset, which is not the same as other multi-unit moving iron headphones. As far as the product itself is concerned, its most suitable front end should be a country tile of 4k or above. The product at this price point will not be said to have a situation that cannot be pushed down seriously, and it can exert its due value. Judging from this experience, NF6 is a custom-made headset that is suitable for tossing and has great potential to be tapped. The NF6 that fully utilizes its strength is very competitive in the 7K price range, but if you want to use the mobile phone with practicality, The effect may be greatly reduced.
This is the end of the NF6's first experience and sharing. Due to the time problem, NF6 did not have enough downtime, I believe it will have some improvement after the good. Taking into account the comparison is more convenient and direct, this time only a few headsets use only the original line of NF AUDIO, if with a variety of high-end wire and even the balance line, NF6 and VE6 will have a better performance, the above is the comparison Some regrets.
