, although Feiao's domestic evaluation has been mixed, it cannot be denied that Feiao is one of the most powerful domestic brands at home and abroad. Since as a large factory, it is also very necessary to provide all kinds of consumers with the products they need. Therefore, Feiao has sorted out FD single-acting coil series, FH ring iron series and FA moving iron series.
, a year ago, FD1, the entry-level item of FD series, came on the stage. Six months later, FD5, the flagship item, came on the stage. Then, six months later, Feiao finally filled the transition in the middle of FD series with FD3. However, FD3 is not only a transitional product, but also a highly competitive product in 699.

1.Packaging and Accessories
FD3 is actually mediocre, and the amount of information is too small for a 699 product. In the middle of the front is a checkline diagram of FD3, supplemented by hot silver and colorful UV processes. At the bottom is a pattern with a little sense of technology, and at the top is an ancestral logo and a small gold logo. There is a print like a manuscript on the side, and the FD3 tick chart uses the same process. Turning to the back is black except for the production information at the bottom, and there is no labeling of product parameters, which wastes more space.

is not compared with that of the eldest brother whose price is more than twice, because it is a small change of FD1, but it is not too distracted to make people feel that this is a product with a higher positioning than FD1.
(back of package)
because the packaging is the same as FD1, the interior is still the structure of the storage box and accessories under the upper earphone.
accessories still have the style of a big factory, a strong and durable transparent waterproof box, a total of 11 pairs of earphone covers in 4 categories, a pair of sound mouths for tuning, and practical small tools such as small brushes and MMCX picking pieces, which are of high quantity and quality.

, in fact, before I got the real machine, I saw some information disclosed by the government first. If I extracted keywords from the middle, I knew that the ID design of FD3 was combined with the characteristics of FD1 and FD5. At that time, I imagined a semi-open version of FD1.
when I saw the real machine, I actually felt a little like the old man's cell phone in the subway, because I put a celluloid on FD5, which was still a little unacceptable to me. However, with the calm ornament of Phnom Penh, it is still very durable and has become accustomed to it over time. The main reason is that the design itself is really not bad.
(Details of the backplane)
got it was this semi-open design. Most of the semi-open designs put the output network directly at the back of the unit, but FD3 changed its normal state and designed this structure at the bottom of the socket. This position happens to be in the auricle when worn. I also tested it. As long as it is worn normally, it will not affect the operation of the structure. In addition, it seems to improve the problems of sound leakage and poor sound insulation caused by semi-opening.
(semi-open)
is not only the appearance and semi-open design, FD3 can be said to have completely inherited the mantle of FD5. The replaceable catheter and acoustic prism are still equipped, or just like FD5, the internal components can be seen as long as the sound mouth is unscrewed. To be honest, at this time I have a feeling that FD5 users have been stabbed in the back.
(Acoustic Prism Component)
the standard two mouths this time are not of different sizes and specifications from FD5, which are used to change different insertion depths, but to change different apertures. The red rubber ring has small aperture, high frequency and soft hearing resistance; the black rubber ring has large aperture, strong analytical force and penetration.
(black rubber ring large screen conduit, red rubber ring small screen conduit)
FD3 uses aluminum-magnesium alloy cavities that are widely used in the industry at present. The same result is five-axis CNC machining with high precision and tight seam. The cavity has also been polished and colored, and the texture of the finished product is still very delicate, but it still has to face the problem of oil contamination with fingerprints. It will be much better if you choose a silver version.

wire is also in place. The standard version is four strands of single crystal copper, which is relatively soft, but the pro version uses the same replaceable plug wire of FD5, and FD5 users are stung again.
3.sound performance
acoustic hardware part has just been mentioned, and it is also the same configuration of FD5. The 2,000 yuan hardware decentralization is still very reassuring. It is also curious how much level a higher-priced hardware can release, especially on a brand that is not well-known, so the performance of FD3 is really not accurate just under one hardware.
the unit part FD3 uses a 12mm DLC diamond ball diaphragm, 32 Ω impedance and 109dB sensitivity. This parameter should be familiar to many people. Indeed, this is the same data of FD5, but the unit diaphragm is still different. This wave of FD5 users has successfully escaped. Because both catheters are worn in the same way this time, the sounds of both catheters will be mentioned.
This evaluation mainly uses portable players and mobile phones as the front end. Compare and refer to Tiantian T5, Ningfan NA2, and Natural Sound NS4. Earplug cover reference standard white silicone cover, 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:No matter what kind of catheter it is, the sound of the final product is a very common fashion style. The whole sounds dark and feels NS4, but unlike NS4 headphones that fit Harman's curve, FD3 is not a more balanced situation with three frequencies, but emphasizes more low frequencies. In this way, when listening to pop music, the sense of atmosphere will be emphasized. As long as it is properly controlled, it can play a certain role in optimizing the sense of atmosphere.
(compared with NS4)
, it is precisely because of the blessing of the semi-open cavity that the sound field performance of FD3 is very advantageous at the same price. The semi-open structure naturally provides an open sound field performance, but FD3 still handles the position and size of each knot securely, and does not move the small theater to the football field because of the large sound field behavior.
triple frequency performance:FD3 belongs to the type of steady play. The human voice is relatively front, the density is good, and there is no obvious bias in the timbre. It can ensure the texture of male voice and the extension of female voice. It is a suitable voice for both men and women, which is very in line with the current state of pop music. It's not like NA2's voice is a bit cold. Although it will cause some lack of details, it can give a more ear-catching sense of hearing. The influence of the two kinds of sound mouths on the intermediate frequency is mainly on the peak of 2k ~ 3k. after changing into a large aperture, the peak shifts to 3k more and raises more, and the hearing feeling of human voice will feel clearer. the replacement of the two kinds is a problem of bias to the type of human voice you like, but no matter which kind of human voice still has good performance.
(Compare NA2)
I'm going to talk about high frequency and low frequency together this time, because the changes caused by replacing the catheter are complementary. According to the frequency response diagram, it is obvious that replacing the catheter does not change the low frequency, but mainly changes the high frequency value. Under the default red small aperture catheter, because the high frequency is eliminated a lot, the value is reduced and the low frequency is more obvious. In this case, FD3 low frequency dispersion is relatively strong, and the thickness of low frequency itself is relatively thick, which is somewhat similar to T5 low frequency, but T5 low frequency will be thinner than FD3, and finally a relatively large low frequency, which will have some negative effects on some musical instruments, but it is a good thing for people who like low-frequency sense of quantity. After replacing the black large-aperture sound mouth, due to the increase of high-frequency value, the corresponding low-frequency will not appear as much as before, and the dispersion situation will be solved to a certain extent. From the aspect of quantity feeling or timbre, it has become a kind of preference for most people.
Comparison T5
the high frequency under the red tone mouth has no position in front of the low frequency and the medium frequency. Although the timbre is still in place, it is difficult to be perceived without the position. After replacing the black tone mouth, the high frequency value increases and becomes clearer. It also achieves a better sense of balance with the low frequency and is relatively smooth, unstimulated high frequencies can also lead to stronger sound adaptability. However, the high frequency of FD3, no matter which sound mouth is used, is not good in quality, and has not achieved more appropriate detail restoration. It is still used as a stable sound tone in the overall sound to ensure the role of listening.
(Feiao FD3 two types of sound mouth frequency response curve)
summary:can still clearly feel that I prefer black sound mouth, especially after learning that Pro version of wire is also a promotion of high frequency, I even think FD3 of black sound mouth is the sound that Feiao itself wants to give, so if you start with FD3, I suggest the first thing is to replace it with black sound mouth.
FD3, as the only earphone item in Feiao in the middle of this year, must be full of expectations for Feiao's fans. For passers-by who are not very optimistic about Feiao, they will also think about what kind of product it is. Although the market has not said anything yet, I guess there should be good market feedback, whether from the promotion of FD1 or the decentralization of FD5, FD3 has done a good job. Horizontal comparison can also be played back and forth. Not only that, FD3 has once again taken the rhythm of high-quality accessories too much. If there is a good response in the market, other manufacturers may follow up, which is a good thing for consumers.
advantages: excellent workmanship, high hardware level
Disadvantages: General high frequency quality, general packaging
