Good News Ripples in Ear-Feiao F9PRO Headset Experience Review

mentioning Feiao, perhaps many burning friends will think of her HIFI player for the first time (I also gradually learned about this brand from the classic X1). In fact, Feiao's product line is quite rich. In addition to players, it also covers earphones (including desktop, portable, etc.), earphones and bluff lines. Especially in recent years, new earphones are emerging one after another. Take the F9 series as an example. Up to now, three models have been released, namely F9, F9SE and F9 pro. The F9 three-unit ring iron introduced earlier has been well received by the vast number of fans for its good sound quality. The two subsequent models are flexibility and evolution based on them. Among them, the SE version cancels the interchangeable line design, and the price is more affordable (one is cheaper than F9, which is beneficial to more small white users), while the F9 pro as the "final chapter" uses a better Lou's unit (the first two are domestic double sound moving iron), and the details are also optimized (for example, the improvement of MMCX interface makes it easy to plug and pull, stronger, etc.). The "main character" of this article is this ultimate evolution version of F9 pro. Let's look at its specific performance:

earphones adopts the design of the common night black background unit cavity box painting, but the most striking thing on the front of the box is not the small gold logo (Hi-Res certification) that has long been "rotten street" in the upper right corner, but the "knowles" Lou unit logo at the lower corner of the same side. The F9 launched earlier adopted the domestic double sound moving iron unit for various reasons, while the evolved version F9 PRO is one of the two new earphones released by Feiao after cooperating with Lou at the end of last year (the other is "Bright Eyes" FH1).

and through the information printed on the back, you can clearly understand that F9 PRO is equipped with Lou's composite moving iron unit-Knowles-30017. It is a one-turn hybrid three-unit interchangeable headset. By the way, Feiao's products are renewed for one year (mainframe) and guaranteed for two years.

box, it can be seen that the arrangement of contents is still very compact. The top is the earphone body "protected" by the black sponge sleeve, and the bottom is a plastic storage box (moisture-proof and waterproof) with quite leather and operation resistance. There are also quite a lot of accessories "hidden" inside.

"behind the pillow" contains "pieces of paper" such as after-sales cards and instructions ":

, the author likes this small black box very much. The irregular facade made up of various strips of different lengths on the front is very beautiful. Of course, the manufacturer also comes with an additional soft cloth bag made of diving cloth. Two kinds of storage, convenient to carry out and home, I like.

I have to say, Feiao, as a "big accessory factory", is still very generous. In addition to the conventional 3.5mm earphone line (with wire control), it also distributes a 2.5mm balance line. It is still very good to match Feiao's own player.

: three pairs of balanced sets, three pairs of low-frequency sets and three pairs of vocal sets (S, M and L sizes), and three pairs of memory sponge sets of the same size. Fully meet the user's listening and wearing needs.

F9 series earphone molds are the same, F9 PRO is no exception. The appearance of the cavity is taken from the shape of water ripples in the water. At the same time, there are good news in the ear, and the beautiful meaning of ripples in the heart is inside. The plug body shell is made of aluminum alloy and is made by CNC technology, fine polishing, sandblasting and anodizing. It has both metal texture and masculinity. It also shows flexible posture and soft beauty. Let's add a few more detailed pictures:

cavity: in fact, the "ripples" ripple shape adopted by the earphone is not only for beauty, but also for eliminating resonant standing waves while ensuring strength.

F9 pro adopts a one-circle, two-iron and three-unit design, of which the 9.2mm moving coil is responsible for medium and low frequency, and Lou's 30017 is responsible for high frequency driving. This combination can be used to dive and analyze. For other parameters, the sensitivity is 106dB, the frequency response is between 15HZ-40KHZ, and the impedance is 28 ohms. Relatively speaking, the front end is relatively "approachable. The moving coil unit uses PEK polymer nanocomposite diaphragm, which has strong toughness, fast speed and light weight. In addition, it also adopts a physical and acoustic double-frequency design, which makes the ring iron combination more harmonious, and the combination of the two can produce better sound.

Although the appearance of F9 family molds is the same, there are still slight differences in specific details, coating process, color matching, etc. For example, F9 pro, its titanium gray color matching is more textured and more classy than F9's red/black color. And the accessories included are also more generous (up to 12 pairs of earmuffs). Of course, in order to make users better distinguish, there are obvious "PRO" marks on the inside of the cavity and the end of the splitter. The L/R logo and red and blue dots are printed near the end of the pin to show the distinction between the left and right ears.

headphones also use the popular MMCX standard interface, and the design of interchangeable wires is convenient for later replacement and upgrading of wires. However, although MMCX has the advantages of strong compatibility and easy plugging and unplugging, it is also relatively easy to rotate, and poor contact is inevitable after a long time. The solution of Feiao is to add a spiral texture to the inner inset to increase the friction and make it stronger.

are not the same. As a frequently used balance wire, it adopts a cross braided wire design. The wires are four cores, and the left and right channels are separated (which can effectively improve the separation degree). The inner core is oxygen-free copper silver plating (to ensure good balance and high resolution). The other wire is made of ordinary TPU material, but it is thicker, has good elasticity and is not easy to wind, and has wire control, which is convenient to use with mobile phones when going out of the street.

F9 pro is designed to wrap around the ears. It fits the auricle more tightly when worn, is more stable when used, and will not fall off easily when exercising. In addition, blue and red metal rings are also added to the left and right sides of the plug end of the earphone cable, so that the left and right units can be quickly identified during normal use, and it also plays a very good beautification role.

three-key wire control board: F9 pro's balance port is 2.5mm (compared with the ordinary 3.5mm earphone line, the sound quality is obviously improved), and it is most suitable to match Feiao's own player. Therefore, here, the author will take X5 3 generation as the front end of the test to talk about the specific listening feeling (this one in my hand is limited red, isn't it beautiful).

is the second flagship Android player launched at the end of 16 years, and the x5 third-generation machine performs well. The appearance is thick and atmospheric, and the workmanship is solid. The IPS touch screen, which is nearly 4 inches (3.97) on the front, is quite conspicuous. A closer look at the surrounding borders at the edge of the screen reveals a fine texture. The asymmetrical design of the left fuselage makes the fuselage not too rigid, but also makes it more refined and industrial. Feiao's classic "Feiao Red" power key and roller design are also perfectly presented. No wonder it has won many awards since its inception. In addition to the two awards known to the general public, Red Dot and IF, it also includes authoritative awards in the circle such as EISA AWARD and annual awards in various countries (this is probably the audio player with the most awards in China).

Both earphone wires are L-shaped elbow designs that are convenient for plugging and plugging:

In addition to the double TF card slot, the X5 3rd generation also provides many interfaces to get more gameplay. The following figure shows the 3.5mm conventional output port and 2.5mm balance port at the bottom of the fuselage, in addition to a digital optical fiber hole. Of course, as an Android brick, good expansibility is very necessary. It is equipped with a UI system that is deeply customized based on Android 5.1 version. Through its own application market, various audio apps can be easily installed, and it is very convenient to listen to/play songs online. Daily operations do not feel stuck.

In terms of hardware configuration, the x5 3 generation is equipped with Ruixin Micro RK3188 as the main control chip, and is also equipped with two AK4490 DACs, and the operational amplifier is OPA1642 and OPA426 (two each); At the same time, independent dual active crystal oscillators are also used, and their hardware performance is quite good. The following listening feeling is the author's subjective feeling of matching F9 pro with the balance port:


佳音入耳 心生涟漪——飞傲F9PRO耳机体验评


because the author has not heard F9 before, it is not clear what improvements PRO has made in sound. However, in terms of recent hearing, F9 PRO is a plug with high completion. The three frequencies are balanced and natural, and the sound is transparent and bright. It is full of charm and especially resistant to listening. Perhaps with the blessing of Lou's unit, the "moving iron flavor" is quite strong.

high frequency is smooth and bright, not harsh. The sense of positioning and resolution are very strong, and the malleability is quite good. The transient response speed is very fast, the details and density are well controlled, there will be no dry and stiff feeling, it sounds more real and more moving. After accessing the balance port, F9 PRO has obvious improvement in layering, transient and analytical power.

The intermediate frequency is transparent and clear, with high reduction and good presence. The voice is clear and delicate, the vocal distance is moderate, and the overall warm taste. When listening to some fresh and cheerful female voices, there will be a lively and cheerful feeling. The separation between the human voice and the instrument is good, and there is no ambiguity. The knot is accurate and thick, with a certain sense of graininess. Although the resolution is high, it is appropriate and not tired after listening for a long time. Under the balance port, the sound is more transparent. The sense of siege and atmosphere have been enhanced.

the low frequency sense is quite sufficient, loose and clean, diving in place, elasticity is also very good, the performance under the balance mouth is strong and powerful, full of power, especially when listening to the style with strong rhythm. In the distribution of the sound field, the depth of the vertical depth is very strong. Although there is a certain expansion in the horizontal direction, it is relatively limited. In general, this plug is used to listen to popular music, small classical music, and jazz, rock and other types have a relatively good performance.

佳音入耳 心生涟漪——飞傲F9PRO耳机体验评


summary:, as the final work of F9 series, the overall quality of F9 PRO is still worthy of its price of 300 yuan higher than F9. The appearance follows the classic style of "Ripples", but the details have been slightly changed, but the internal moving iron unit has become Lou's blessing, which brings a balanced, natural, comfortable and listening sound. The accessories are also very kind (two-wire, two-pack and up to 12 pairs of earmuffs). However, if you want to give full play to the real potential of F9 pro, a player with a balance port is the best choice (Feiao's X7 and X5 series are good choices).
