is getting heavier and heavier, and Feiao FH9 is used for evaluation.

FH9 is between FD7 and EM5, and the listening feeling is thicker and fuller than FD series, and the quality is also first-class.

sorry to keep you waiting this time! Feiao FH9 ring iron earphone has been in use for a long time. The content has been delayed until now, not because of procrastination, but because this earphone has been giving us surprises in sound experience. In order to better show the use of FH9, the earplug cooking time is relatively long. How do you say this is also a proud flagship ring iron earplug, the new audio and video is also decided to simply enable the long test mode, giving enough time, let's go to the earphones to bear down and slowly ponder.

FH9 is not difficult to push, has always been proud of the FH series is like this. The preferred player is Feiao M11 Plus LTD, which uses SF sleeve and standard filter screen. The wire uses the original wire of the 4.4mm balance interface. The sound of the FH9 is somewhat similar to that of the FH7, and you can feel the passionate sound style. This is in stark contrast to the calm voice of the FA series. The brightness and spatial sense of medium and high frequency, including the extension of extremely high frequency and the extension of low frequency, have been significantly improved. The new video thinks that the semi-open cavity is of great help to the expression of sound style. Even with so many optimizations to the low frequency, the semi-open cavity FH9 can be controlled properly.

FH9 is not lively and transparent. On the whole, it is relatively modern. This belongs to Feiao's current good style. It is also very bright under the 3.5mm single-ended interface in time, and the dynamic performance of earplugs is also in place. Compared with the treble of FH7, FH9 is brighter and more transparent this time. The extension of high frequency is good, and the sound density of the connecting part of high frequency and medium and high frequency is also good. FH9 explains the characteristic of "catching ears" well. FH9 is more transparent than Feiao's FA9 pure moving iron earplug, while FA9, as the flagship moving iron earplug of the old product, has an advantage in high frequency density. In the high frequency to high frequency part, FH9 compared to FA9 dynamic, analytical power is very competitive. Compared with the newly launched FD7, the voice of this FH9 is more convergent, and the quality it should have can also be reflected.

FH9's relatively restrained mid-frequency style determines its overall performance is very balanced and elegant. Feiao's ring iron earphones do not have any connection problems, and the overall feeling is very smooth. However, the intermediate frequency of FH9 is more enjoyable than that of Feiao FD7 in terms of vocal performance, and has a sense of heaviness than that of FA9. Moreover, the intermediate frequency resolution of FH9 is slightly higher than that of FA9, while the performance of musical instruments is not as good as that of FA9 and FD7. Listen carefully to FH9's vocal density seems to be a little fuller than FD7. In the performance of large dynamic symphony, FD7 is easy to control, and the sound level is clean and delicate. In contrast, FH9 has good explosive power, but it is still not outstanding compared with FD7. The intermediate frequency of FH9 will be more balanced and neutral than these two products.

the low-frequency part, the deep part of the dive is still slightly higher than FA9,FH9 sound is more refined and clean. The new video and audio have tested many exaggerated dance music with low frequency. It is believed that the low frequency dynamic range of FD7 should be an obvious advantage. However, if you like the kind of sound that is relatively restrained from the point to the point, but can give consideration to both elasticity and quantity in listening performance, FH9 is more suitable. Even if it is not a balanced interface, FH9 still has a good sense of low frequency hierarchy, which is somewhat different from FD7. It is a neutral and style-oriented player with M11 Plus LTD. The new video compares Feiao's flagship earplugs of three different product lines. In fact, it is slightly unfair to FA9, but this earplug does have the power of World War I. Of the three products, FH9 is the best to push, followed by FA9 and finally FD7. The choice of headphones should also be determined according to their own front end.

, looking back at FH9 itself, the handling of sound is Feiao's artistic pursuit of tuning. FH9 has a good sense of sound space and line, plus replaceable filter screen and replaceable wire. This is FH9's characteristic play, which makes this product even more beautiful. The design of the FH9 replaceable filter is the same as that of FH7, with two filters for high sound and bass. It may be that the original FH7 storage rod is easy to lose. This time FH9 is fixed on the metal plate like other manufacturers. After the filter screen is replaced, the hearing changes greatly, which is more direct than the replacement set. Different sound styles are combined according to the various covers attached, which is more playable than FA series adjustable switches. Compared with the default two filters, the treble filter can make the FH9 sound more slender, improve the high frequency density and empty inspiration, and the corresponding low frequency sense will have a certain loss. The use of bass filter screen enhances the performance of medium and low frequencies. If the user wants to change the proper amount of low frequencies, he needs to replace it with a sponge cover on this basis. Unlike the bass cover, the bass cover can make the lower half of the sound more plump and directly obtain this stimulation from the sense of hearing. This is not the same as the sponge cover of the bass filter, which brings some relatively soft but makes people feel that the bass is very good.

FH9 is single crystal silver wire, not copper wire, which is the same as FD7 before. The design of replaceable plug has been popular in Feiao's medium and high-end products. If you want 3.5mm single-ended or 2.5mm or 4.4mm balanced interface, you can change it yourself. However, the difference between them is that they adopt different compilation methods. FH9 is eight-part, FD7 is four-part, and the wire cores are all 224 cores. The sound difference between this wire and monocrystalline copper silver-plated wire is still quite large. Compared with FH5S Pro, FH9 wire has better analytical power, and the density and texture of high frequency have been well improved. However, it is not that Feiao must use silver thread for his flagship earplugs, but to make these flagship earplugs have a wider range of music applicability. If FH9 is replaced by Feiao's monocrystalline copper silver-plated wire (LC-RC), the high-frequency performance will not be so bright, the low-frequency sense will increase, and the whole sound will not be balanced enough. So a look at FH9 with this special preparation method of silver thread or a certain reason.

In addition to being a "six-iron one-circle" unilateral seven-unit product with full selling points, FH9 is a very rich product with six sets, which can replace the sound guide hole and a pure silver wire with high purity. The moving iron unit is a 13.6mm DLC dome diaphragm unit developed by Feiao, which is responsible for low frequency. The medium and high frequency is Lou's six-moving iron combination, the intermediate frequency is Lou's DFK composite unit customized by Feiao, and the high frequency is a SWFK-31736, the moving iron unit is close to the sound nozzle, and the efficient conversion of the moving iron unit is used to ensure the analysis and extension of sound. On domestic stacking products, Feiao is definitely the best one at the same price. The new video and audio are still sensitive to the concept of six iron, because as early as 8 years ago in the fever environment, the top flagship moving iron earphones would only use six units or eight units. At that time, the ring iron earplugs were just emerging with AKG K3003. Now there are so many units in the ring iron earphones, which makes people curious about the sound of FH9.

, with the continuous iterative update of Feiao, it has indeed promoted the development of this market with its own strength. Some people always think that Feiao's products lack characteristics. In fact, Feiao has silently changed the fever environment when promoting the progress of this market. When others were still struggling with the earplug cavity, Feiao used 3D printing. Now many manufacturers have started to blow up their own 3D printing, but Feiao has all switched to metal cavity to iterate its own manufacturing process. Before watching the FH9 conference, the new audio and video individuals prefer the design of FH5S. When we know whether this earplug cavity uses pure titanium metal as the shell or CNC cutting, we feel that the cost is too high. After all, titanium metal is famous for its hardness. I'm afraid the yield and production cycle cannot be guaranteed if I want to realize a complex appearance design like FH5S.

tried to read some information, titanium earplugs as a metal shell does have a lot of other metals and alloy materials do not have the advantage. Titanium, which is used as a core component of aviation, can provide better strength and hardness and reduce the resonance of the earplug cavity. The use of high-cost and hard titanium as the shell material is also related to Feiao's design in the FH series. The semi-open cavity turbocharged bass technology can replace the sound nozzle design. To achieve a more ideal state, these three technologies need to take into account a reliable cavity housing. The semi-open cavity and the replaceable sound nozzle have nothing to say, while the super-running turbocharged bass technology used in the FH series uses structural modification of the sound guide hole to make the low-frequency unit sound guide hole into the shape of a turbine, thus increasing the sound wave directivity, reducing the transmission loss and realizing the physical "low-pass filtering" function.

ring iron earphones, as the dream configuration of the new video and audio fever, seem to be full of ring iron earphones today. The new video and audio think that the reason why iron earphones can be popularized so quickly is that both manufacturers and users agree that it is still a new product with new technology at that time. In the early days, many products had problems with frequency division and tuning. With the increase of market demand and the maturity of technology, the products of iron earplugs have gradually matured. At present, there are a large number of ring iron earplugs on the market, and the sound orientation is different, which will inevitably cause aesthetic fatigue. At the beginning of the new video, it was said that this FH9 is the kind of product that I have rarely seen over the years that can give a surprise experience.

for Feiao, FH9 has reached a new height in sound, configuration and production process. Compared with the previous FH7, FH9 has improved too much and has certain advantages over other products at the same price. However, in the face of a market with a smaller and smaller stock, the sales volume of HiFi products at the top may have a certain impact. This year, Feiao has already positioned its flagship product prices around 4000 yuan, and many manufacturers have followed up this pricing strategy, because this price is not too high for some non-enthusiast users. From the perspective of products at the same price, New AV believes that Feiao is obviously a more sincere choice. After all, the configuration and production process are all real costs here. With the maturity of Feiao's tuning, the time has come to tear off its inherent label. Feiao FH9 also features the voice of FH series, which is the way to break the game in the future.
