begins with Yan, pour in your heart! Listen to Feiao FD5

Feiao has now formed a relatively complete product layout in the earphone market, and its product series are finely divided according to unit types and wearing methods. In-ear wired headphones can be regarded as the largest product line among them, including three series of ring iron hybrid, pure moving iron and pure moving coil. Compared with the FH series of ring iron and FA series of pure moving iron, which are more abundant in product models, the FD series representing pure moving ring has only a FD1 "facade" of less than 400 yuan ". However, with the launch of FD5, Feiao began to complete its "jigsaw puzzle" in the pure mobile headset market ".

The new design has good texture.

only from the larger number of product models, it is not difficult to judge that FD5 is much higher than FD1. As far as the current FD series is concerned, Feiao developed FD5 as the flagship product of the series. Feiao has always dared to try in the design of earphone products. From the varied panel design to the customized modeling with both texture and comfort, every time I experience Feiao's earphone, its modeling always attracts my attention in the first place, and there are many bright spots in it. If many of Feiao's earphone products are still continuing certain family design elements and changing on top of them, FD5 has applied a new design language.

, it changed the shape of most Feiao headphones or oval or similar customization to adopt a cylindrical cavity, with a "regular feeling". But this is not all. In the design of the panel, Feiao drew some inspiration from the three-dimensional water texture elements of previous products, and four curves penetrated the panel. The curve is not a simple and straightforward design, but has ups and downs and different widths. Take a closer look in your hand, you can see that the curve and panel show a natural shadow. With the change of the angle of sight, you can clearly feel the flow of light and shadow, bringing 3D relief-like three-dimensional and light and shadow visual effects. This effect is due to the "exposure development" technology used by Feiao on FD5. The different textures of mirror and matte are interwoven on the same surface, and the transition between them is natural and smooth. The matte part of the panel is not an ordinary coating, with a sandblasting feel, high fineness, mirror effect of the curve touch has a smooth and warm feeling.

can see dense regular small holes between the curves, forming a semi-open back cavity. Its function is to quickly release the pressure and relieve the pressure of the user's ear canal. The FD5 shell is made of 316 stainless steel and CNC technology. After four rounds of manual polishing and polishing, the metal cavity can be clearly felt on the palm of the hand. In addition to bringing outstanding texture and durability, stainless steel can also reduce the generation of cavity harmonic resonance, taking into account visual effects and practicality.

"Change One Change" Brings Strong Playability

from its entry-level products of several hundred yuan to thousands of flagship headphones, the interchangeable design is basically the standard of Feiao headphones. FD5 uses the common MMCX interface and comes standard with a single crystal copper-plated silver earphone wire. At the same time, the other end of the earphone line adopts the design of in-line interchangeable audio plug, which comes standard with three plugs of 2.5mm/3.5mm/4.4mm. For most users, even if they do not purchase additional earphone lines, the standard earphone line can also meet the needs of accessing various equipment.

if you think that FD5 "can change lines and heads" is all, then you are wrong, because FD5 can also change the sound guide tube. It provides two sizes of sound guide tubes, which are fixed on the cavity by screwing. The original intention of this design is to adapt to different users to obtain more comfortable wearing and sealing. Among them, the small sound tube can be used with a customized three-section set, which is mainly to meet the particularity of some users' auricles, so that it can go deeper into the ear canal. At the same time, the change of the caliber of the sound tube will also affect the sound style. It can be said that the three "replaceable" designs make FD5 have more "permutations and combinations" in sound performance ".

▲ The plug part of the earphone cable is equipped with a direct plug-in replaceable structure. Three plugs of 2.5mm/3.5mm/4.4mm are standard. One line meets the needs of different equipment of users.

listeners like to call Feiao a "big accessory factory". On the one hand, it is a joke, but it is more because the standard accessories of Feiao products are indeed quite rich. As the current flagship product of the FD series, FD5's "dowry" is naturally not inferior. In addition to the aforementioned earphone cable, sound guide tube and plug, the standard HB5 storage box is very eye-catching. The contrast design of yellow and blue, the delicate texture brought by the pressure-changed leather, and the magnetic belt buckle, both the grip feel and the texture of opening and closing are excellent. The crystal super-soft fabric and velvet lining inside, together with detachable spacers, can not only give better protection to the earphones placed in them, but also flexibly combine the placement positions of various items. This is the storage box, which needs 99 yuan to purchase separately on e-commerce.

▲ FD5 adopts the design of interchangeable sound catheter and provides two calibers of different sizes.

In addition, Feiao also provides 13 pairs of earplug sleeves of different types and materials for FD5, including low frequency sleeve, equalization sleeve, vocal sleeve, three-section sleeve and sponge sleeve. It is worth mentioning that Feiao comes standard with an MMCX clip for FD5 (provided by Japan's Final Inc), which can easily remove the earphone cable from the earphone, thus solving the problem that the earphone with MMCX interface is tightly connected and is not easy to pull it off by hand.

▲ Feiao's reputation as a "big accessory factory" is naturally not a false name. FD5 's "dowry" is quite rich.

internal design sound quality first

In order to meet the positioning of FD5, Feiao has newly developed a 12mm large diameter full-frequency moving coil unit. For the key diaphragm part, DLC diamond ball top plus beryllium diaphragm suspension ring is selected. Beryllium has the characteristics of ultra-light weight, high rigidity, and good toughness. This combination can make full use of the physical properties of the two materials to balance the sound conduction speed and internal damping, improve the sound efficiency of the treble frequency band, and effectively reduce the diaphragm Segmentation vibration and high-frequency harmonic distortion. At the same time, in order to solve the time delay phenomenon caused by different sound wave propagation paths, Feiao also installed an acoustic prism device in front of the diaphragm dome, so that the center and edge of the horn diaphragm can synchronize to the sound mouth to obtain more accurate High-frequency junction image and smaller phase deviation. It adopts an external magnetic structure design on the unit magnetic circuit, so that it can place a larger volume of magnets. It uses a high magnetic flux N52 magnet with a magnetic flux of 1.5 Tesla. With the Japanese large black ultra-fine CCAW copper-clad aluminum voice coil, higher energy conversion efficiency and lower distortion can be obtained.

In addition to making a fuss about the unit, Feiao has also invested a lot of energy in the design of FD5 cavity. In addition to the semi-open cavity design mentioned earlier, it also adds a "volcanic pile" structure to the back cavity design, using the principle of standing wave formation to enhance the low-frequency diffusion of the back cavity, reduce standing waves and reduce distortion. At the same time, there is no curve mutation point inside the cylindrical cavity structure, and the resonance and reflection inside the sound wave transmission will be greatly reduced, which is also helpful for improving the sound quality performance.

audition experience

Because FD5 has three "replaceable" designs, let's talk about the experience of replacement. The first is the replacement between the earphone and the earphone line that we often come into contact. In the past, I tried Feiao's headphones with MMCX interface, and every time I pulled out the wire, it was a more "painful" process. Because the interface and the pin are tightly combined, the joint position is small and it is not easy to focus on, pulling the earphone wire hard and afraid of damaging the wire. It is much easier to remove the earphone cord with the standard MMCX clip of FD5. Align its notch with the seam of the pin, and then press it inward slightly to separate the MMCX pin. Although it is a gadget, it has greatly improved the user's experience when changing lines.

▲ Although this gadget is not very impressive, it solves the problem that MMCX is not easy to pull out.

the plug at the other end of the earphone line is also easy to replace. To remove the plug, you only need to turn the female end clockwise to separate from the male end, and then hold the male end and pull it out. It should be noted that because the surface of the plug is smooth, it is more difficult to pull the male end directly by hand. It is better to wrap the plug with something similar to 3M cloth first, and then it is much easier to pull it out. Replace with a new plug, first determine the bump of the female end. The bump is inside the female end. Pay more attention, align it with the groove of the male end and push it in, then turn the female end counterclockwise and tighten it. Because of the bump design, users don't have to worry about inserting the wrong pins.

FD5 is installed by default with a large sound guide tube, which is fixed or disassembled with the cavity by screwing operation, and is convenient to replace. The size of the guide tube has a certain impact on the sound quality. The large size is more balanced, and the small bass will be enhanced. The latter needs to be matched with a three-section set. Speaking of which, let's talk about the wearing experience of FD5. The default medium-sized equalization sleeve is more suitable for me with a large sound guide tube. After wearing it, the silicone sleeve has a moderate position to penetrate into the ear canal, which has little pressure on the ear canal, but the sealing is good enough and has a good passive noise reduction effect. The comfort level of the contact place between the earphone cavity and the auricle is good, the relatively heavy metal cavity will not increase the burden, the ergonomic design and reasonable weight distribution ensure the stability of wearing, even in the process of moving, it will not let the user feel that he wants to adjust it. With the medium sponge sleeve, I think its sealing is further. The filling feeling after wearing it is obvious, and the comfort is also good. Replace with a small sound guide tube and match it with a small three-section set. However, the three-section set is not suitable for me. It cannot completely penetrate into the ear canal. This match is more suitable for users with deeper ear canal.

According to the wearing experience, I chose a medium-sized equalization sleeve and a large-sized sound guide tube, and listened under the balance interface. FD5's "one ear" sense of hearing surprised me-the 13th song "Pipa vs. Saxophone" in hivi's audition disc, the first round of pipa plucking has caught my ear, the texture of instrumental music is fully revealed, the music between the left and right ears is clear and smooth, and the ending finish is long. FD5 shapes the outline of the instrument very well, the hearing is full and clean, and the details are rich. Only a little attention can capture some slight tremors on the pipa string. With the appearance of Sachs, the tone of the instrumental music under FD5 is pure and restored. When they are ensemble, the primary and secondary between the two instrumental music are clear, with a clear sense of space, which sounds lively and interesting.

in the vocal part, this carefully developed 12mm large moving circle on FD5 not only has a typical loose and warm moving circle style, but also presents some different flavors. Feiao did not deliberately tune in the warm and thick direction on FD5, and the sound was hardly significantly stained. The singer's position is centered and does not stick to the ears like many moving-coil headphones. But when listening to some music with prominent vocals, such as Lin Junjie's "Song for No One" and Tian Fuzhen's "All Can", you will find that the lingering voice under FD5 is just right. It can create the image of a full-fledged singer. The details between the lips and teeth retain the reality of the recording scene, and at the same time weaken too many dental sounds, making the whole listening feeling gentle and not exciting, and finding a balance between details and sileness. FD5 is different from the "female poison" of the Iron Triangle. Its voice is less warm, more real and delicate, and has another taste of listening.

Feiao did not specifically pursue the adjustment of FD5 low frequency, how deep the dive was, but it was enough to make the listener feel its good quality of low frequency. The sense of quantity, elasticity, diving... FD5 low frequency every presentation appears "just", is the kind of every time is very full and solid sense of listening. Even in electronic and rock music with more low frequencies, it will not bring the listener the bad feeling of bursting his head or chaos, and it also shows good control while showing enough explosive power. The high frequency of FD5 is clear and smooth. Although the details are not as detailed as those of moving iron headphones, they are clear and real enough. At the same time, its high-frequency extensibility is also easy, the transient response is fast, and burrs will not be felt. FD5 can create a certain sense of sound field space, and the positioning and level in space are accurate and clear. It is more suitable for performing instrumental solo or small woven music. The space is just right, and it is a bit difficult to go to the big organization.

, although only looking at the model numbers, there is still room for the Feiao FD series to go up, but at present, FD5, the flagship product of the series, already has enough to move people. After several years of hard work, Feiao has formed its own set of ideas in the design of earphone products, and it has become more and more mature. Exquisite workmanship and solid materials ensure the presentation of product effects. FD5 is the kind of product that is easy for consumers to fall in love with at first sight.

listening, this feeling should be further deepened. In the selection and design of the unit, as well as the acoustic structure, "stacking" and "innovation" have gradually become the "routine operation" on Feiao mid-to-high-end headphones ". Their combination brings FD5 a balanced and listening sound style. I especially like its performance of instrumental music and human voice. At the same time, the three replaceable designs on the earphone add a lot of playability to it. Exceeding the overall quality of social status, the good after-sales policy of one-year renewal and two-year warranty, Feiao FD5 is worth listening.
