, alas, feiao, feiao, it is too industrious to send new products. I don't know how many feiao new products have been evaluated in succession. it's really not a strange py deal with feiao! It's really that Feiao's new products came out too fast and too fast. Originally, when we thought that the flagship of Feiao's single-moving coil headset was FD5, Feiao launched FD7 after a year. Both pricing and configuration are the real flagship, and FD series will officially end for a period of time.
FD7 also bears the lofty expectations of Feiao, and has also introduced the improved FDX on FD7 as a product to commemorate the 14th anniversary of Feiao. I don't know how many people guessed the price of the last 3999 and dispelled the desire of many people to spend, but in any case, FD7 is still looking forward to being a gift for the 14th anniversary of Feiao.
Feiao/FiiO FD7
1. Packaging and Accessories
packaging box naturally uses Feiao's new design. Compared with FD3 and FD5 packaging, I also prefer FD7 packaging a lot. The models and selling points on the left side of the front are arranged, and the explosion diagram of FD7 is used as the background. On the right is the rendering, the advanced feeling is still in place.
packaging front
and some information was marked on the bottom. Although I didn't like this kind of design that was a bit wasteful of space before, I didn't feel this way this time. I don't know why. If you remove the envelope, you will put the inner box with headphones. After you take away Feiao's usual instructions, you can see that the first layer is FD7 and the storage bag, there are two pairs of replacement sound mouths, and the lower layer is some other accessories.
package
flagship products should have flagship accessories. The wire is naturally a replaceable plug design. Unfortunately, there is no additional 6.35mm plug. This time, three pairs of SpinFit earphone covers of different sizes have been added (look at dune next door), and the storage bag is naturally HB5. The catheter is equipped with a thin catheter from FD5, and another catheter with a different inner diameter is also added. However, this time the tool used to disassemble MMCX has changed from the final clip to Feiao's own pick, which is still a little worse than before.

2. Appearance and workmanship
black and gold color matching
I believe that many people will have the feeling of "coming again?" when they see the appearance of FD7. Although this is the case in fact, it is necessary to say for Feiao that not only the current appearance design, but also the built-in acoustic prism components should have appeared on FD7 at the beginning. As a result, FD5 was launched first for some reasons. As a result, FD7 was launched only after FD3 was released.
Backplane Details
Although this appearance FD5 was used first, there are still some differences on FD7. For example, in addition to changing the color matching of the cavity to black, the semi-open voice net is also changed to dark gold, which is not more than traditional The gold is dazzling and prominent, but it is also more calm. Feiao named this design "Kurokawa Liujin".

to be honest, this design is not a design recognized by many people. Many people think that this design is really not good-looking. However, after re-matching on FD7, the two are basically the same. However, judging from the final color matching, such piano black is still much more advanced than silver. At the same time, with gold embellishment, FD7 is a step late, but it still has the status of eldest brother.
acoustic prism component
this is the third time I have seen the acoustic prism component. How effective is this component? After so many products, they naturally have their own fixed numbers in their hearts. The volcanic reactor design for diffusing standing waves used on FD5 is still included in the design this time.
Work Details of Headset Cavity
Feiao products has always been obvious to all. It has always been in the first echelon. FD7 is the flagship. Five-axis CNC and multiple polishing are naturally standard. Needless to say whether it is good or bad.
distribution wire
this time, the wire is also a pure silver wire with a 224 core. The flagship should look like a flagship. It is needless to say that the plug can be replaced and arranged directly. The most interesting place is a small detail. The material of MMCX plug is not common plastic, but it is replaced with stainless steel like the cavity. Both the texture and the sense of integration have been improved. Although the cost is increased due to the material and processing difficulty, I still agree with such a level of attitude at this price.
3. Sound performance
after the release of the two products with lower positioning, both the exterior design and the acoustic components on the FD7 have a "technical" feeling, but in fact, if you think about it carefully, the FD7 is the real sound of the whole design. FD5 and FD3 are more like testing the water of technology. What is gratifying is that the two products also have good market performance.
FD7 unit has also been greatly upgraded, from FD5 diamond ball top plus beryllium plating to pure beryllium ball top plus beryllium suspension diaphragm. Although it is said that the hardware cost has increased a lot, it is better in terms of transients and details due to the addition of beryllium in sound. At the same time, the impedance is also increased by 50 Ω, the sensitivity is 112dB, and the driving conditions are not high when the background purity is improved.
This evaluation mainly uses portable players and Bluetooth earphones as the front end. The earplug cover refers to the standard black silicone cover, using the default catheter, the earphone has been carried out50 hoursRoutine cooking machine, refer to "Interesting Listening Headset Evaluation Test Collection" for the audition track.

impression of hearing and style:, if I want to use one word to summarize the voice of FD7, I think I will choose the word "steady" without hesitation. The voice of FD7 gives people the feeling that it is very solid, without very stylized tuning, and without any unnecessary dazzling skills. FD7 is a voice that wants to tell you that this is a flagship moving circle that is flying proudly.
the voice of FD7 this time is not "younger", it is a voice of all ages. Thanks to this, FD7 has a very good adaptability to all kinds of music, especially after the semi-open design, even classical has a good performance, and it is a very, very strong product with omnivorous ability. At the same time, the disadvantages are also obvious. Such FD7 voice is more difficult to "poison" into the hearts of a certain group of people. After the price is high, proper stylization is not a bad thing.
cavity
Although FD7 tuning is not particularly biased, it still tends to be a little bit colder. This coldness does not make the sound rigid and boring, but makes the sound more regular and calm down, which is also conducive to the sound field being more regular and wide, especially in such a semi-open cavity.
triple frequency performance:As I said just now, because FD7 does not have a very stylized tuning, the three frequencies are also relatively balanced, which is one of the reasons why it has good adaptability to different types of music.
FD7 is the idealized low frequency in in-ear headphones, with appropriate sense of quantity and clear image, that is, it is not too small or too diffuse, which is just right. In the face of moderate drums, the low frequency is also relatively mild, and fast drums can also ensure a simple and powerful sound. At the end of adjusting the sense of quantity, FD7 is no longer as popular as FD5's voice, but is somewhat classical, supplemented by a semi-open structure. FD7 has a good "sense of presence" and has no problem when facing live. The rebound is also very fast, there is no extra residual sound, which ensures the cleanliness and tidiness of the overall sound.

intermediate frequency, I think this is really not a disadvantage. The human voice knot is similar to FD5, with high density, delicate, larger and more tasty. The female voice is slender, the sense of line is obvious but not very soft. The male voice has a good amount of information while the texture is in place. The overall human voice is not so young, and it is still a feeling of all ages, suitable for all ages. There is no problem in the restoration of musical instruments. The overtones are lit up with some faint sweetness. It is very obvious that although it is a moving coil unit, it is not worse than moving iron or higher price moving coil in intermediate frequency analysis, but it can be comparable. However, it has to be said that when FD7 is used to deal with some commonly used audio sources in mp3 format such as 320kbps, the human voice knot will be placed very large, which will greatly affect the sense of hearing. However, it seems that FD7 is too much to kill chickens with such a sound source...
is only a single moving circle and has no blessing from other units, the high frequency performance of FD7 is still good, the ductility is excellent, there is enough information, and there is no problem of partial brightness on FD5. However, if the high frequency is required to achieve a reasonable performance, the requirement for driving is relatively high. If the driving is insufficient, it will be obviously darker, and there will be a good improvement after reaching a certain driving force, but in the end it will not be too bright.
Feiao/FiiO FD7 frequency response curve
summary:FD7, as the flagship of Feiao's single-moving circle, has a high degree of completion under such positioning and pricing, and it is difficult to pick out any major problems for it. If you want to talk about the biggest problem, it is actually a question of the launch sequence. Under the condition that almost all the technologies on FD7 have appeared on the lower products of Feiao's own product line, it is difficult to give people a feeling of shine at the moment.
In addition, FD7 also represents Feiao's ultimate understanding of the sound of the single-acting circle. No matter what attitude Feiao was before, I think I can try it out under the current wave of the single-acting circle to see if there will be any change in the impression of Feiao. Whether it has done better or not, whether there is still much room for improvement.
advantages: excellent workmanship, excellent accessories
Disadvantages: High weight, slightly affecting wearing
