"Iron" Covered with "Circle" Skin-Feiao FA9

as the saying goes: you can't have both fish and bear's paw. the difference between the moving circle and the moving iron has been talked about since they were used in headphones, and each has a considerable number of fans. Today, the gap between the moving coil and the moving iron is gradually decreasing. The mixed earplugs of the ring iron have been everywhere for a long time. Each of them takes its length to make up for its shortcomings. This is also the most easily thought of all kinds of golden oil scheme. However, there are always some people who have unique ideas and only rely on the moving iron unit to realize the two hearing senses of moving coil and moving iron on one earphone. The effect seems. Yes, it is the main character to talk about this time, Feiao FA9.

, as the flagship product of Feiao's active pure moving iron product line, FA9 is equipped with Lou's 6-unit moving iron. 31736 composite unit is responsible for high frequency and extremely high frequency. The intermediate frequency is 33877, and the low frequency is 31618 composite low frequency. This is only foreplay. The really wonderful part is that FA9 also uses a 3D printed maze acoustic filter with a length of 80.6mm straightened. Through this low-frequency maze, excess medium and high-frequency filters in the bass unit are filtered to obtain a more pure and better low-frequency performance (the high-frequency wavelength is shorter and the attenuation is faster than the low-frequency). The use of low-frequency mazes in earplugs is actually nothing new. Both the 846 and fearless acme series have made such attempts. The addition of the fourth-generation DLP high-precision 3D printing technology also laid the foundation for catheter design and frequency response control accuracy, and also brought a better production process. The transparent transparent cavity is matched with the refraction effect of the diamond-like cutting panel., The light and shadow are particularly bright, and playing in the hand has become a kind of enjoyment.

In addition, FA9 is also equipped with three tuning switches to adjust sensitivity, high frequency and medium and low frequency respectively. Although I personally don't like this switch tuning method, determining a sound with the highest degree of completion will make the choice easier, but in other words, adding a switch makes the sound more playable, and tossing the sound collocation is also a big pleasure for burning friends. The tuning switch of FA9 is relatively successful. The difference of each sound is obvious (the details will be explained later). It can even be converted between "iron taste" and "circle taste" instead of being limited to fine-tuning of a certain frequency band. This is why I call it "multiple personalities", rather than simply changing several daily habits.

As for accessories, major accessories factories will never disappoint people. 6 earmuffs with different sound orientations, with tuning switches, are 48 sound combinations, which are forced to choose the rhythm of phobia. Of course, SF sets are enough to wear all-round and comfortable in daily use. The blue leather storage box also carries a small cloth bag to hold the thread clip and tuning lever. The wire is made of 8 single crystal copper silver plated wires, expanded mmcx interface, transparent injection molding pins are exquisite in workmanship and metal red and blue rings are used to indicate the left and right sides (it would be better to replace the replaceable plug, FA9 is worth balancing to obtain better separation and sound field).

explained in advance that the following switch selection and listening feeling are all obtained with Xiao Mo Ju and have more or less personal listening preferences. If you have different views, please communicate.

I have a lot of clumps on hand, so I am familiar with hufi's voice. When I put on FA9 for the first time, I didn't believe in my ears. This is not the flying pride who likes line feeling and frigidity, but more like a clumps on the warm hufi route, the outline of the human voice is not even as good as the ghost of Zefeng's "Qi" (the ghost can be said to be the representative of the layered paste), especially the loose low frequency and diffusion. It is hard to believe that this is a moving iron sound. And the high-frequency extension is also relatively convergent, completely without the sharp sense of the multi-unit moving iron that takes the analytical route, this style also gives people a sense of analysis and the illusion of poor separation (even makes me think that this wiring is dragging a little back? But there is no other mmcx balance line on hand, so it can't be verified), but in fact, in the amount of information FA9 gives a little bit, just need a little. It is true that FA9 intentionally softens the outline of the knot item in each mode, slows down the attenuation speed, hides the simple and fast character of the moving iron, and simulates the hearing feeling of the moving circle. Of course, the shadow of the moving iron can still be found in some switch combinations at medium and high frequencies. The performance of the sound field is quite satisfactory, and it is more suitable for the small compilation of popular songs. The horizontal width is relatively limited and there is a certain depth, but the voice will change the mouth shape and position with the different switches.

is the sensitivity switch, which should be the switch with the most obvious influence on the sound change. Under high sensitivity, the details will be richer, especially for the overtones of musical instruments and the weak tones in the background. However, what makes me more uncomfortable is that the overall sound under high sensitivity will seem to be directly pasted on the face, which is a little messy and less regular. However, when the sensitivity is low, it can be clearly felt that the whole sound is like wearing a tights, which is compact and toned. It outlines some lines and has better sound density. Although the sense of separation from each other is not capable, there is no sense of high sensitivity. Of course, the extension of extremely high frequency is bound, and the high frequency has a little dark pressure. As far as I like, I choose to keep the sensitivity low to get a better and stable sound. As for switches 2 and 3, I think it can be understood as an enhanced filter adjustment. The following is an example of several switch combinations I tried.

2 and 3 are fully open: This model is officially called "beautiful treble" and I call it "chicken blood model". In the communication with friends, I also learned that this combination may be preferred by users who are used to moving iron sounds, and it is also my favorite combination. Under this combination, the sound is full of tension, which is more suitable for large-scale opening and closing scenes. If you are listening to pure tone and symphony, this combination should be the first choice, especially for strings like violin. This combination should have the best gloss. For pop songs, this combination is more suitable for the expression of female voices. The mouth shape is the most prominent and clear, and the details are rich. The night deer, which I have been fascinated by recently, is very ear-catching, neutral and slightly grainy, and the guitar overtones in the background will not be dull. And songs like Sawano Hiroyuki, which use percussion instruments and effects extensively, with complex backgrounds, can also be more effective in this combination. This is also the reason why I put this model first. Its lively and beautiful character and adaptability to all kinds of music are the most comprehensive side of this plug.

2 off and 3 on: This mode is a balanced mode, and it is also the most successful side of FA9 wearing a mask and disguised as a "circle". It should also be the taste that Feiao wants users to taste most. I prefer to believe that this is a bold attempt made by Feiao. Although this mode ranks second in my preference, I have to say that the listening feeling under this combination is really good. The texture of the moving circle is made by the quality of moving iron, which is loose and delicate, and surpasses the moving circle at the same price in the density of intermediate frequency. Compared with the combination of chicken blood mode, this combination is more restrained and clean, very resistant to hearing, and the line feeling is between the treble mode and the popular mode,, the vocals are mellow. Of course, the most worth mentioning is the addition of low-frequency maze to low-frequency performance, which is very close to the feeling of an advanced moving circle in terms of quantity, diving and layering. At the same time, the extremely low frequency is easy to perceive, the base is very solid, and the double bass or piano sound is more complete and full. Moreover, it will not appear procrastinating when rendering the atmosphere, reminding you from time to time that the "circle" is still wrapped in six "irons" under the skin, which in a sense gives people a feeling that it is not a circle but better than a circle. In the equilibrium mode, the distance between human voices is relatively moderate. In this mode, it has a good performance for all kinds of Mandarin, Hong Kong and Taiwan popularity. It is more tasty to listen to Jacky Cheung or Hacken Lee. However, this is also a point that I am more tangled with. Although the equilibrium mode is very resistant to listening, it will not make you worry about dental sounds, but the whole reverberation will be less and cleaner, on the contrary, it gives people a feeling of "almost". There are limitations in shaping the sense of space, and the sense of margin is more obvious, which is exactly what this kind of Hong Kong and Taiwan songs need.

2 on and 3 off: This mode is a popular mode, um, the mode of moving times and playing times. It is obvious that this mode may be the most flavored one in various combinations. The "paste" has reached the extreme in this combination. Although the knot of the vocal instrument is still too large and the depth is basically compressed under low sensitivity, the whole sound appears somewhat flat, and the human voice even runs into the head. A slight increase in the low-frequency sense but more changes than the equilibrium mode will be reflected in its looser and slower speed. In this combination, the sound will appear lazy, which is more suitable for slow rhythm such as jazz but has certain requirements for low frequency.

2 and 3: Officially, it is called "surging low frequency". When I adjusted to this mode, I suddenly felt familiar. After thinking and recalling, I finally remembered that the sound of this mode and ROCK in Letu PMEQ have the same skill. This mode is also the one with the heaviest iron flavor on FA9. It is recommended to use this combination with high sensitivity. The timbre is cold and the line sense is the strongest, which highlights the metallic sense of instruments such as cymbals and electric guitars. These instruments will have obvious texture enhancement. At the same time, the sound field will be closed and the position will be lower, and the human voice will be back and more Slimmer. However, in this mode, there is a slightly depressing feeling, especially for high frequency and extremely high frequency, which gives people a feeling of being pinched off, and the muscle tightness is not relaxed at all times. It may be more appropriate for hardcore metal rock, but I would never choose this mode for listening. The strong personality makes it less balanced and resistant than other modes.

"iron" covered with "circle" skin, I think it is perfect to describe FA9. And this is not just as simple as putting on a vest, it is to simulate and strengthen the listening feeling of the circle with iron quality, and naturally integrate the two. In the beautiful high-pitched and balanced mode, FA9 has created a high-quality "moving circle" appearance. These two combinations are also my favorite tuning. FA9 splits several personalities with different personalities through switches on its positive sound bottom. This undoubtedly expands the original EQ and filter adjustment on the player to a new dimension, greatly improving playability, of course, some switch combinations are still deficient in the degree of completion, and it is really difficult to adjust the whole body with one pull.

has also written about M15 before. Like this FA9, it can be said to be a brave step taken by Feiao. M15 is a further exploration of HiFi flavor, while FA9 is an attempt to diversify tuning. Feiao is constantly bringing new surprises to people. I also hope to see Feiao polish more details on the basis of these attempts. New tricks can bring freshness to people, but the intensive cultivation of details can be recognized by more people.
