comprehensive experience beyond imagination! ---- Talk about Feiao 7-unit ring iron flagship headset FH9

's talk about Feiao FiiO 7 unit circle iron flagship ---- FH9. Feiao FD7 and FH9 headphones have been in my hand for half a year. Since the end of the previous year, I have been busy with all kinds of trivial things every day, and people are a little tired. Many products have been placed on the bookshelf without unpacking. Since the end of February, the demand and export of some products have been somewhat affected, and the whole people have suddenly been at leisure. As a result, FH9 was opened and listened intermittently for more than a month. It was also time to share with you the feeling of listening and using.

I am personally concerned about the following aspects:

One Circle Six-Iron Architecture
Following the release of FH7, Feiao took 2 years to build a brand-new six-iron structure, and for the first time on FH9 was equipped with the second generation of self-developed 13.6mm DLC moving coil unit to be responsible for low-frequency sound generation. DLC diamond material has the characteristics of high rigidity, low weight and high damping coefficient, which can bring better transient response and effectively control nonlinear distortion. At the same time, Feiao redesigned the magnetic circuit structure of the moving coil unit, and the magnetic density was 20% higher than that of the first generation unit, bringing stronger and more leisurely dynamic performance to the sound generating unit.

Six Lou's moving iron units are responsible for medium and high frequencies. FH9 is equipped with the intermediate frequency composite unit 62305 deeply customized by Feiao and Lou's of the United States, as well as the classic ultra-high frequency moving iron unit SWFK-31736. After 2 years of careful polishing, the coordination and excess between the units is perfect, and the connection is very delicate.

Semi-open acoustic back cavity, S.Turbo acoustic turbo-charged structure and unique notch device, these rigorous and scientific internal acoustic design of headphones bring you a perfect sound experience.

titanium housing
FH9 titanium metal shell is quite a surprise! There are also several earphones with titanium cavity on the market, such as UM MAVEN, FitEar Titan, etc. The selling price is not close to the people. Different from the 3D printing process used in these earphones, the titanium metal shell of Feiao FH9 is made of five-axis CNC digital processing. The forming of a pair of shells requires 39 kinds of tools and 9752 kinds of precision milling. Such complicated processing difficulty also brings great challenges to the output. Titanium metal low quality, high hardness, high strength characteristics, to bring the user light wearing experience, but also can effectively suppress the harmonic generation and reduce the cavity resonance.

Wire Upgrade
FH9 is equipped with an 8-strand 224-core Leeds structure twisted high-purity sterling silver wire, and is equipped with a straight plug-in screw lock type replaceable audio plug. At the same time of following the expansion type MMCX earphone interface, the material of MMCX has been upgraded, and the stainless steel elbow plug-in is adopted, which forms a high degree of unity and coordination with the titanium earphone shell in color and appearance.

sound

The second-generation self-developed DLC diaphragm low-frequency moving coil unit adopted by Feiao FH9 has a more obvious improvement in low-frequency strength and clarity. The 13.6mm large diameter and S.Turbo patent supercar are the use of turbocharged bass technology, which gives FH9 outstanding dynamic performance. Its low frequency is vigorous and exciting, with impressive dive depth and atmospheric performance. The semi-open cavity design also controls the low-frequency residual sound and distortion extremely well, creating a relaxed and comfortable sound field and a more natural music presentation to some extent. By matching FiiO M15, Astell & Kern SE180 players, we can obviously perceive the above advantages of FH9 low frequency. The phenomenon of low frequency and slight softness of early home ring iron products no longer exists in FH9. The excellent responsiveness of the DLC diaphragm also gives the FH9 an excellent sense of speed, which is more amazing than the excellent details of this earphone and the in-depth description of the texture of low-frequency instruments. Take it to listen to Stark's six Bach unaccompanied songs, whose rich and delicate qualities reflect the music's introverted and profound, elegant and long temperament to the fullest. Through these bits and pieces, we can clearly see that Feiao FH9 has a higher understanding and display of music emotion and music language expression while focusing on stimulating the quality of the unit. In fact, we can capture these advances as early as FD5, but the multi-unit flagship product talks about this progress or shows the style more thoroughly.

units and the processing of human voice or intermediate frequency are no longer problems for later loop iron products. FH9 vocal positioning is very scientific and is not affected by low frequencies. It has a solid background, but to the greatest extent to maintain a natural balance of timbre. FH9 is very positive for the performance of human voice, with remarkable thickness and density, fine details, transient electric wind control, and proper tone rendering. Nature, mellow, jumping off, with the vitality of music, can be said to use the quality of perfection and appropriate embellishment to stimulate the appeal of music and on-the-spot performance.

The high frequency is delicate and thorough, and the extension is excellent. The wide sound field brought by the semi-open cavity also injects some air into the high frequency. The notch resonant cavity can eliminate the harmonic resonance generated by the cavity, the sound tube and the ear canal, thereby suppressing the generation of the dental sound. This scientific cavity design makes the FH9 transparent and slim high frequency more pure, and the excellent control of the player is just like. With M15 listening to Paganini's 24 songs, FH9 can accurately interpret the details of double overtones, bow jumping, string playing and bowstick string playing in the repertoire, and show the musical vocabulary of flexibility and jumping. I have to admit that few earphones can make high-frequency transparent and sharp, and some make transparent and sharp into a style to capture the first hearing of enthusiasts, but they will get tired after a long time, while FH9 really won't. At least with a balanced sound tube, there will be no such sharp feeling.

aside the sound field and the positioning of musical instruments, I am more intoxicated with the perfect integration of FH9 seven units. I have come into contact with some multi-unit earphone products. Some of them are expensive and the music details are prominent. However, if I listen carefully, it can be said that they are all broken. It can be said that individual multi-unit headphones do not take good care of the integrity of the sound while highlighting the listening details. And we can feel the delicate frequency band transition and perfect music integrity in FH9, and we can feel the natural music emotion. As mentioned above, while focusing on stimulating the quality of the unit, Feiao FH9 has a higher understanding and display of musical emotion and musical language, which is commendable to me personally.

in addition to these, think carefully, this headset is not particularly impressive? That must be the outstanding dynamic and sound field performance! As an earplug product, FH9 has a good performance ability for large-scale classical music. Its wide and regular sound field, scientific and accurate positioning of musical instruments, and strong dynamic and detailed display make it possible for small headphones to listen to large scenes. The FH9 sound is solid and precise, retaining the integrity of the music while taking care of the details of various instruments.

why I give Feiao FH9 such a high parity, especially in the sound part, the praise is out of control. I think it is largely because of the price of this headset. Enthusiasts who often come into contact with portable HIFI products should know very well that HIFI earphones have two obvious trends in the past two years: first, regardless of brand, efforts have been made to highlight the sound-price ratio of low-end models, and some models, especially domestic models, have performed very well, even leapfrog and strange operations. Second, high-end models test the thickness of audiophile wallets by continuously stacking the number of units and types to improve sound quality performance, and such products abound. Feiao FH9 is more like a showstopper who has pulled the pricing of high-end products down the altar. It has a carefully crafted titanium metal shell, a 7-unit ring iron structure that took two years to set up, a semi-open cavity, S.Turbo super-running turbocharged bass technology and a unique notch device design. Combining the excellent sound quality brought by these factors, it can insert the screw lock type replaceable audio plug and a rich accessory package, combined with 3999 price, it's hard not to be tempted.



Then the question arises, will there be FH11 in the future?
