Feiao FD5 Flagship Moving Circle Earplug Experience: Representative of Cheap Sound
I believe that no matter which music lover you are, you will have a certain "moving circle complex". This complex is just like when you saw EVA's Ayanami, you silently had a good impression of the three no girls in other animation works, simple and profound. We like the natural, warm and surging sound performance brought by the moving circle unit. Even in today's era when multi-unit moving iron and ring iron are rampant, the light of the single circle has not faded. Many audio manufacturers are obsessed with developing the maximum potential of single-acting coils, and many enthusiasts are keen to study the combination of single-acting coils. As the most traditional electroacoustic transducer, the moving coil unit is still young and charming.
I will be curious about the sound performance of every flagship moving ring earplug on the market. I can often see the research and development strength of an audio brand from these products. Besides, compared with the impetuous multi-unit earplug market, single moving ring earplug is obviously practical, and high-quality models emerge in endlessly. I have also shared many personal favorite works of flagship moving ring earplug before. This time, the main character is Feiao's flagship moving ring earplug.
At present, there are quite a few earphone products in Feiao. Among them, FD series is Feiao's special pure-moving earphone cable. In addition to the newly introduced FD5, there is also an FD1 for entry-level positioning. In addition, Feiao's EM series is also a mobile earphone, but it focuses on the product line of flat-headed earplugs, such as the flagship EM5. In addition, there are FH series, FB series of Bluetooth headphones, FW series of real wireless headphones, EH series of headphones, etc. Does it feel that the product line is extremely rich? The basic Feiao you need has been covered, and most importantly, Feiao has controlled their pricing in a very suitable position, which is quite cost-effective compared to the same configuration earplugs on the market.
For FD5, the official price of stainless steel cavity shell, 12mm moving coil unit, developed diamond-like ball top plated beryllium diaphragm, eight-strand single crystal copper pure silver wire, replaceable plug and accompanying rich accessories is only 1998 yuan. As Feiao's flagship work, FD5 is not only sufficient in configuration parameters, but also unique in cavity design. The pricing of 1998 yuan is really conscience. After I got the earplugs, I also immediately started the machine-making project. It should be noted that ordinary users do not need to pay too much attention to the matter of moving the earplugs. They can listen normally at ordinary times. The reason why there is a machine-making project is that we hope to get the best sound quickly to help judge, after all, there is still more or less difference in sound between the newly opened moving-coil earplugs and the moving-coil earplugs after a period of time.
let alone how the earplugs are, FD5 accessories alone make me feel luxurious.
The specially customized leather storage box is lined with suede texture, which can effectively protect the FD5 of the stainless steel shell from scratches. The MMCX ASSIST tool purchased from the original Final factory can facilitate users to quickly disassemble the MMCX wire plug (although such a plastic clip, the original price is one in 40 yuan). Cleaning rods, 12 pairs of different types and sizes of earplug sleeves, replaceable wire plugs, replaceable acoustic conduits, etc., these are standard accessories for FD5, which have a good performance in practicality and playability.
back to the earplugs themselves. This time Feiao made FD5 cavity shell made of stainless steel, and specially designed a waterfall-like panel texture on the shell. Through the relief texture, you can also see the fine holes inside. This is a semi-open rear cavity specially designed by Feiao, which can help earplugs release pressure and balance sound.
It can be said that FD5 should be the most prominent product texture in Feiao's earplugs at present. The stainless steel panel is frosted and the back side is polished. The visual impression brought by this metal material makes the whole cavity have a certain level of advanced feeling. Feiao also calls it their "artistic acoustics 」. To be quite detailed, the wire joint part of FD5 is also made of the same stainless steel material, which makes the earplugs have a strong sense of unity.
this time, FD5 catheter is supported for replacement. In addition to the default catheter, there is also a small-caliber catheter. Different sizes of catheters also make FD5 have two ways to wear it. If you want to wear better sealing and better sound at low frequency, then replace it with a small-caliber catheter, and then cooperate with three-section sleeves to directly go into your ears. The deeper you insert, the better the sound. Of course, if you wear it like this, you will basically lose some comfort. If you can't accept the wearing method of the three-section sleeve, it is recommended to use the catheter with the default caliber. Personally, it is recommended to match the equalization sleeve or the memory sponge sleeve, and the sound performance will be more comprehensive.
wire uses eight-strand monocrystalline copper pure silver wire, Litz Type2 braided and twisted structure, and MMCX interface. It still supports Feiao's in-line replaceable plug design. There are three specifications of plugs available: 2.5mm balanced end, 3.5mm single end and 4.4mm balanced end. They are all relatively conventional configurations of Feiao flagship products, so there is not much introduction here.
let's talk about the sound part next.
The diaphragm of FD5 is a diamond-like ball top coated with beryllium diaphragm. The 12mm moving coil unit is matched with a unique acoustic design, which makes the sound of FD5 have a good dynamic performance. FD5 is not difficult to drive, and its 109dB @ 1mW sensitivity is not very good at the front end, but it is still more recommended to match high-quality front-end equipment here, which is helpful to give full play to the potential performance of the moving coil unit. In terms of the default catheter matching equalization sleeve, under the matching of Feiao M15, the tone of FD5 is balanced and mild, and the warm feeling of the moving coil unit makes the sound of FD5 quite audible, and its low-frequency sense is not much, but the texture is excellent, and the elasticity and force have a strong impact, especially when listening to some European and American popular, the high-quality low-frequency performance is very extra.
from the official frequency response curve, the frequency response curve of FD5 is quite close to the Harman curve, so what is the Harman curve? Simply put, this curve is calculated by Harman through a large amount of scientific data. When the frequency response curve of the headset is the performance, the sound performance is "best", or the most popular. You can use this Harman curve as a reference value. After all, this may be the greatest common divisor for most people to judge good sound. Then the frequency response curve of FD5 is close to the Harman curve, which also means that the tuning of FD5 is a style that the public will accept.
in fact, the voice of FD5 does not only maintain a sense of balance, but also has the "sense of music" that most people like, but this "sense of music" is different from the previous EM5. It is not rich, but soft. The elasticity of low frequency, the nature of medium frequency and the smoothness of high frequency shape the high-quality listening feeling under the balanced tone of FD5. It should be noted that the tone color of FD5 at the single end and the balance end is obviously different. When the single end is connected, the overall tone color of FD5 is relatively neutral, with little burr feeling, and it is basically a relatively stable style. After the balance end is replaced, the medium and high frequency part of FD5 will be prominent, and the overall brightness will be higher than that at the single end. It may have a more exciting listening feeling when listening, however, due to the characteristics of the balance end, the overall sound quality of FD5 will be higher. The tone color can be neutralized by replacing the earplug sleeve. The playability is still quite large. You can try more and combine the most suitable sound.
for me, the top-level moving-coil earplugs not only need to be "flat and stable" in tone, but also need to have pleasing ability in style. FD5 has done this to a certain extent, and the price is only 1998 yuan. It has enough high-quality moving-coil sound. Of course, the voice of FD5 is not impeccable. Compared with the top moving earplugs with higher prices, the voice of FD5 is not loose enough. In performing some fast-paced songs, it will appear "manic" and not calm enough.
To say that in the plug introduced by Feiao this year, I personally really prefer the two high-end moving circles: FD5 and EM5. You know, making a moving earplug is actually easier for users to ring powder than making a moving iron earplug. The birth of FD5 and EM5 is the beginning of Feiao's further steps in the earphone field.
FD5 dare not say that it is the best one in the flagship moving ring earplugs, but it must be the one with the highest cost performance at present. "Pretty sound" means that it is right.
