long time no see, I miss it very much! Hello everyone, I am Feiao Santos.

time is like a blink of an eye, and the summer season has come in a twinkling of an eye. In this hot summer, Feiao presented a new product launch conference for everyone, bringing a desert oasis to quench their thirst to HiFi fans in the hot sun.

Compared with the flagship FD5, FD3/FD3Pro seems to be more like a wind chime in the court, with a gentle and gentle song. The simple round appearance reminds me of those leisurely summer afternoons, which are interesting and pleasant. But when I actually hand and understand its configuration, I immediately felt the reversal of the poles-"boy, this is a bit unusual. ''

As usual, take a quick look at the main parameters of FD3/FD3 Pro:

brand new DLC diamond diaphragm moving coil unit/front acoustic prism device/semi-open rear cavity acoustic cavity/aluminum-magnesium alloy body/2 pairs of replaceable acoustic conduits/FD3 high-purity single-crystal copper wire/FD3 Pro Exclusive high-purity single-crystal copper silver-plated wire.

of course, there are still many details and hidden items, such as the full manual polishing five-axis CNC machining combined process, 2.5D blue glass plating panel, etc., which will not be discussed here, but will be discussed in detail later. Now let's have a look and see what the performance of this new force in the moving circle will be?

Appearance

took it with 5D2... the old man's cut picture quality is a bit overwhelming.

First of all, FD3 has two colors: black gold/silver with copper thread body; FD3 Pro is a black, gold and black thread body. The difference between the two can be judged from the difference in thread body color.

, as a new force in the flying and moving circle family, will be a blockbuster in the same level at the beginning of its positioning. At first sight, FD3 has a round and warm appearance, which is very atmospheric and has an eye edge. However, under this simple appearance, it has a not simple texture. It is completely hand-polished and collided with CNC five-axis technology. The texture is uniform and the luster is bright. "High-end ingredients often choose.

one's favorable impression of FD3 comes from this. The purity and simplicity make one generous in all kinds of environments. However, if one looks closely, each piece of celluloid panel is different, personalized and restrained. Finally, it covers a 2.5D blue-plated glass panel, which is transparent and crystal clear. The pleasure brought by this appearance belongs to itself and is comfortable.

Specifications

comes to the specification chapter is the core area of FD3, just as FD3's propagandition' new students, not just new sounds' can see some content. We have already taken a quick look at some of the main configurations above, and friends who are careful may have noticed that [the new DLC diamond diaphragm moving coil unit] is wrong, isn't this FD5 already? Yes, the flagship moving coil FD5 has already appeared DLC diamond ball top technology, but this time it is new and different.

First of all, let's know what are the characteristics of DLC diamond materials?

'DLC diamond, full name Diamond Like Carbon, is a substance composed of carbon element, similar in nature to diamond, and with graphite atom structure. '-- From Baidu Encyclopedia

it has the characteristics of high hardness, high resistivity, and extremely small friction coefficient. When applied to the acoustic earphone diaphragm, the high hardness can effectively reduce the segmentation movement during vibration, and the extremely small friction coefficient brings extremely high transient response speed. The performance of high resistivity on the diaphragm is that the internal resistance of the material is large, and the distortion of the sound can be effectively controlled, and it will not occur when the previous signal has stopped, the diaphragm is still scattered aftershocks, increasing distortion. To sum up, the DLC diamond material is mainly fast, accurate and less divided on the earphone diaphragm.

where is the new diaphragm of FD3 this time? Is FD5 also DLC?

FD5, as the flagship moving circle series, the big brother first took on the role of being the most advanced technology pioneer in feiao. DLC diamonds were highly praised by fans after they were put on the market as the top of the diaphragm. Therefore, FD3 has inherited a strong gene and has brought into play a new era -12mm full-size DLC diamond diaphragm. Yes, the whole diaphragm is made of DLC diamond material. This is a new life and.

is that FD3 is also equipped with the latest application of the Feiao moving coil family-the front acoustic prism device, which is expected to be widely used in subsequent products. Why is this configuration popularized? The reason is very simple. After adding such a switch inside the limited headphone cavity, it can solve the time delay caused by the sound wave propagation path of the cavity, adjust the ultra-high frequency phase characteristics, improve high frequency diffusion and eliminate high frequency standing waves. It may sound complicated. In other words, its existence makes sound waves less delayed and propagate more accurately.

remember the patented technology for balanced pressure relief of front and rear cavities on FD5? In order to better balance the air pressure in the cavity, the semi-open back cavity design carefully created by the designer also continues to FD3; the difference is that this time the pressure relief hole is designed above the MMCX connector of the earphone in order not to destroy the round and simple design concept of FD3, and maximize the use of every inch of the earphone space; effectively balance the air pressure in the cavity, eliminate the pressure of the eardrum, and wear it, you can find the subtlety of this design.

see here, many fans will inevitably have doubts 'FD3 configuration is the flagship configuration, but why to launch FD3 Pro? 'Yes, FD3 in the configuration is indeed a leapfrog existence, as we said at the beginning of the article, at first glance, the wind bell in the court, gentle and quiet. I believe FD3 is enough to cope with the use environment of most burning friends and first burning friends. However, there are still a group of burning friends who pursue perfection. Like me, they have a geek's heart and pursue a higher level of pursuit. FD3 Pro is prepared for us. Under the condition that the internal configuration of headphones has gone very far, the wire will be further improved. FD3 is a high-purity monocrystalline copper wire with 4 strands of 120 wire core, and the joint is 3.5mm single-ended. FD3 Pro is 8 strands of 152 high-purity single crystal copper silver-plated wire, and provides in-line interchangeable audio connector design. 2.5/3.5/4.4mm single-ended or balance is fully matched.

Experience

from the moment you get FD3, the specially processed laser hollowing process on the package makes the cover full of crystal-clear gradual discoloration. This gradual line outline is unforgettable. The view of the chip module at the bottom of the front can also produce different changes through different angles of sight. The design drawings on both sides also depict the characteristics of the product itself. This time the packaging ceremony is still full.

side adsorption closed design, the first thing you see after opening is the instruction manual, which is also a reminder for people like me who seldom read it... after opening, it is a distributed structure up and down, with the earphone body and wire on the top. The black paper below is the package of the accessory package. After opening, you can see the transparent accessory box, all accessories are in it.

, the first thing to do is to benefit from the patented technology of balanced pressure relief in the front and rear cavities adhered to by the Feiao moving ring family. At the moment of wearing it, it will not feel any pressure and it will be very comfortable to listen to it for a long time. Friends who are familiar with Feiao earphone products must be familiar with the MMCX expansion interface, which is easy to plug in and easy to use, and, it fits more with the arc of the back of the ear and listens more freely. The left blue and right red distinguish the design, so I don't need to talk too much ~ you can find small surprises by playing carefully, and everyone's feedback is the source of continuous improvement ~!

hearing, with the blessing of full-size DLC diamond diaphragm, the sound segmentation movement is reduced, the distortion is effectively controlled, and the extremely small friction coefficient can bring ultra-high transient response. Speaking of which, burning friends should have some eyes in their hearts. Yes, FD3's overall quality characteristics are very crisp and neat, never muddy, and even with the blessing of the front sound prism device, the performance of the moving coil unit in high frequency analysis is also very good. The low frequency and intermediate frequency have always been the strengths of the moving coil. After the hardness of 12mm full-size diamond comes up, it dives in place and is surging and powerful. Everyone gets different feelings in terms of listening. Personally, I think FD3 is very suitable for listening to pop, vocal, Hippop and other types of music.

Here are some of the tracks that individuals have listened:

Summary

, the comment area will be deducted 1 and arranged.

to the final conclusion, how do we evaluate a good earphone? Maybe different listeners have different answers, which should be powerful, analytical, fashionable and low-key. Yes, everyone has their own preferences and standards. However, as the first echelon of HiFi in China, Feiao's feedback and expectation to burning friends has always been a constant task. The first thing to do is to listen to everyone's opinions and continuously optimize where they can be seen, even the bending radian at the small MMCX interface is the result of multiple measurements of different people before trial production. What is invisible is the continuous increase in internal costs. FD3 is a good illustration of Feiao's persistence. For example, the front acoustic prism on flagship products, the balanced pressure relief patent, and even DLC diamond materials are further expanded to the whole diaphragm; it also brought the FD3 Pro version to those of us who are geeks on the route. In the space for improvement, the Pro will be in place as soon as possible. Home run! Of course, this is sincerity, and it is also a piece of heart that can be done.

brings every touch, interacting with products and expressing with products. Everything is in the actual feeling of every listening.

believe that FD3, a new force behind the waves and moving circles, can leave a good experience for everyone with its super-high configuration!

I am Feiao-Santos

I'll see you next time ~!
