Feiao FiiO F9 Pro Three-Unit Ring Iron In-Ear Headset Evaluation Report

Feiao Ripple F9 Pro is a planned earphone after the introduction of F9 earphone, and it is also the most anticipated product for fans who care about Feiao. The reason is very simple. As a three-unit ring iron earphone, Feiao F9 and F9SE are responsible for high-frequency moving iron units, while F9 Pro will use Lou's 30017 unit. The price of F9 is 698 yuan, while the price of F9 Pro is 998 yuan. The price difference of 300 yuan is changed for a Lou 30017, which sounds very attractive.

F9 Pro is the leading role in Feiao and Lou's electronic cooperation products. The FH1 we evaluated and recommended not long ago may be a supporting role. After all, the words Lou's 30017 unit have been printed on the packaging box of F9 Pro. The FH1 single-unit moving iron treble is not so famous. However, FH1 uses a shell and acoustic structure different from F9, and the plastic shell also saves a lot of cost for FH1, so the price of FH1 is lower than that of 500 yuan, but the sound performance is definitely obviously better than that of F9. So the F9 Pro follows the F9 design, and can it be greatly improved after updating the moving iron unit and re-tuning?

here, let's briefly review the F9 series headphones and introduce the F9 Pro headphones. Feiao Ripple F9 series, the appearance uses aluminum alloy shell, ripple shape, internal cavity also creates irregular cavity and better strength shell due to ripple shape, which has not changed on F9 Pro. After the F9 headset was released, Feiao once introduced a 598 yuan F9 SE, which canceled the design of interchangeable lines, but was cheaper than F9 in 100 yuan. Feiao seems to have adjusted the angle details of MMCX interface to make plug-in more convenient and reliable.

compared with F9, Feiao F9 Pro has an exclusive appearance of titanium gray, while F9 and F9 SE have two appearances of red and black. According to the official description, the moving coil unit is still a PEK polymer composite diaphragm, while the moving iron uses a double-unit Lou 30017. On FH1, the moving coil unit with higher evaluation seems to be different from that on F9 Pro. F9 Pro comes standard with a 2.5mm balanced headphone line and a 3.5mm headphone line with wire control, which is consistent with F9 configuration. On earplugs, both F9 and FH1 are six pairs of two types, while F9 Pro is 12 pairs of four types. On the inside of the F9 Pro headset and the metal splitter of the earphone line, the word PRO is printed.

In addition to the dark small opening and gray translucent large opening earplug sleeves used on F9 and FH1, F9 Pro also adds two varieties of white translucent large opening earplug sleeves and Comply earplug sleeves. Grey translucent and white translucent earplug sets have the same opening size and are relatively large, but the material of the inner red rubber fixing column is different. The gray translucent earplug is harder, while the white translucent earplug is softer. Comply also has a large sleeve opening and a relatively short wearing depth.

, let's go directly to the subjective listening part. The test is based on Feiao's X7 MarkII AM3A and Le Zhibang Monitor 09. The contrast headphones include Feiao FH1, Feiao F9 and Sony Z5. The test is mainly based on dark earplug sleeves with small openings. It is believed that this is the most balanced sound among the 4 earplug sleeves. The following will specifically compare the differences between the four earplug sleeves.

overall impression:Lou's high pitch is definitely not a false name, but where is the famous work of 30017? It seems that it has always been a mystery. Some people don't admit it when they say that K3003 has been used, and there is no conclusion when they say that UE900 has been used. However, two things can be confirmed. First, the moving iron of the 30017 double unit is definitely much stronger than the counterfeit product with double sound. Second, the high frequency of 30017 is definitely not Lou's top level. Although F9 Pro uses the same moving coil unit as F9 from the official description, the adjustment is quite different and has changed greatly. With the addition of the treble unit upgrade, the overall sound is much more normal than F9. In terms of high frequency, the improvement of detail quality is also reasonable. However, the advantages of excellent intermediate frequency connection on FH1 and natural medium and high frequency hearing do not appear on F9 Pro.

high frequency performance:Feiao F9 Pro is the most exciting under the white translucent sleeve, and it is more convergent under the small opening sleeve, with the fastest transient and the best density. No matter what kind of earplug cover, the high frequency extension of F9 Pro does not show the delicacy and sense of space under Sony Z5. However, even under the most exciting white translucent cover, the high frequency of F9 Pro will not be particularly sharp [for example, compared with the most exaggerated FLC8 and the abnormal Meizu Flow]. The high frequency of F9 Pro is relatively restrained, the sound is stable and clean, there is no extreme pursuit of density, and there is no obvious elevation. The transient speed of the sound is relatively fast, but the sense of space is general, and the sound level is not rich enough. It is more like a moving iron high frequency that is willing to show the taste of moving iron. There is a gap with the advanced moving iron treble that can already show slack and delicate levels.

under the reputation of being inexplicably red 30017, in fact, we can't find a headset that dares to say that we are 30017. Feiao F9 Pro became the first. In terms of F9 Pro's performance, its extremely high frequency extension is not top-notch, but its performance in sound density, dynamics, especially high frequency, is quite good. The analytical force, level and sound field are greatly affected by the earphone structure. The design of F9 Pro can only say that it will be qualified and the sound is still tight. The connection between medium and high frequency is poor, there is no natural connection state of FH1, and it is far worse. Of course, the density and dynamics of high frequency of FH1 are weaker than those of F9 Pro. In the higher part of high frequency, the analytical force and detail performance of FH1 may be slightly more distorted and slightly weaker in extension. But in the mid-high frequency part, FH1 won.

intermediate frequency performance:FH1 is a category that is willing to strengthen the thickness and sense of the intermediate frequency in the ring iron earphone, while F9 Pro is a category that is weak and tight in the ring iron earphone. To what extent is it weak? Compared with Sony's N3AP and Z5, the intermediate frequency is more medium and high frequency, and the thickness of the intermediate frequency is relatively weak. When listening to the recordings of David Roth and Ingram Washington we like to use, you will think that the recording was probably recorded by the electret microphone of the mobile phone, right? Squeeze in your throat! Although it is much better than F9 in texture, the intermediate frequency is still not good enough. To improve the intermediate frequency, you can replace a better player and sound card. Feiao's two players have a very general degree of adaptation, and of course the improvement is limited.

this style of intermediate frequency, we can describe it as the characteristics of intermediate frequency to medium and high frequency crowding. The sound is weak and young. However, it seems that due to the good performance of the moving iron unit, the sound is relatively clean and does not feel too dry. Under the dynamic performance, the intermediate frequency of F9 Pro is just like a headset that is not easy to push, with insufficient strength, so the explosive power is very general. Intermediate frequency is obviously not the long term of F9 Pro, but it is better than F9.

low frequency performance:Feiao has always liked to adjust the intermediate frequency and low frequency tightly, but FH1 did not do so, nor did F9 Pro. If F9 Pro is based on the same bass unit as F9, then this change of F9 Pro is quite surprising. In the description of intermediate frequency, everyone should see that F9 Pro does not do well in the sound dynamics of the intermediate frequency starting to approach the middle and low frequency, so it feels that the human voice is crowded on the Internet. Although there is not much problem in the details, the style is still too partial. The middle and low frequencies of F9 are relatively close to the middle frequency. Although the dynamics are not good enough, the connection thickness is still acceptable.

but F9 Pro did not do so. It took more obvious care of the low frequency and the deep part of the low frequency dive. This makes the F9 Pro's medium and low frequency dynamics and thickness quite average, and listening to the cello is relatively weak. However, the depth of low-frequency diving and the relaxation of the lower low-frequency part do have. It can be considered that the resolution of this part of low-frequency is improved. After all, compared with FH1, the low frequency of FH1 can't dive so deep, the sound is not so loose, and the distortion should be a little larger than the low frequency of F9 Pro, but the low frequency sense and thickness of FH1 are obviously better than those of F9 Pro. The low frequency of F9 Pro is more suitable for low frequency with very slow listening speed, general sense of strength, good diving, and too slow transient. If, you will feel that the low frequency is too soft and the hair is burnt. However, if the low frequency of FH1 sounds mushy, it is because it feels too much after being squeezed, causing loss of control. Except for the resolution of the deeper part of the low-frequency dive, the performance of this moving coil unit of F9 Pro is far inferior to that of FH1.

Comparison of different earplug sleeves:In addition to the earplug sleeve with small opening, F9 Pro also provides a white translucent earplug sleeve. The red cylindrical texture in the earplug sleeve is relatively soft. Its high frequency will be the brightest, the intermediate frequency will be the worst, and the low frequency speed will be faster, but the medium and low frequency will be more missing. The gray translucent plug, high frequency is actually more open and dynamic than the small opening earplug, but I still don't like such bright high frequency. Comply's earplug sleeve has the most relaxed sound. The level and sense of space of high frequency and medium and high frequency will be improved, but the low frequency will also become relaxed. The low frequency, which is already very slow in transient, does not seem to be suitable. Of course, depending on the type of music, you can choose your own earplug cover..

we have actually played through the performance of F9 Pro in FH1 evaluation, we speculate that headphones launched on F9 platform will not surpass future products on FH1 platform. Lou's 30017 unit and CNC ripple aluminum alloy shell are a burden to the cost of F9 and F9 Pro earphones. The in-ear catheter is not independent of FH1, which also makes the tuning of this part empty talk. It is certainly an indisputable fact that the smaller the number of moving iron units, the better the connection. However, whether the connection between the medium and high frequencies of the two-unit moving iron or the F9 Pro, which is the first publicly claimed to be 30017, can only achieve this level, we think it is definitely a design problem, and it is very possible to achieve it. Feiao F9 Pro's early taste value is also relatively limited. Maybe you can buy one to hear what Lou's official designated 30017 is?
