Ring Iron Advanced Choice, Listen to Feiao FH5s Headphones

ring iron series has always been the leading product in Feiao's earphone family. It is not difficult to see its important position from the large number of products and the rich price range covered by this series. Among them, a circle of three-iron earphones FH5 released three years ago, as the main player in the Feiao thousand-yuan market, laid a solid market foundation for Feiao, who entered the earphone market at that time. Three years after its launch, this classic product has welcomed the "successor" FH5s. Although FH5s is an upgraded alternative to FH5 from the perspective of its name and Feiao's positioning, FH5s is more like a brand-new product with its own DNA based on all aspects of product information.

"Long Lin" possession texture upgrade

Feiao always surprises me in the design of new earphones, whether it is new design elements or combinations of different materials. This time on the FH5s, Feiao's designer was inspired by the dragon scales on the traditional Chinese god beast dragon. The black decorative sheets laminated on the upper cover of the earphone are shaped like scales, and between the "dragon scales" is an air-guiding net with dense small holes. The precise combination of the two brings excellent layers and texture. At the same time, the black gold color matching brings a calm and atmospheric visual perception. In addition, FH5s also provides a silver gold color matching version for consumers to choose from, which is another unique taste.

to FH5s, Feiao's custom-like front cavity design has developed to the third generation. In terms of materials, aluminum-magnesium alloy materials are used. After five-axis CNC process, one-time grinding, three-way manual polishing, and then sandblasting, anode coloring. The final effect is that the earphone cavity has a delicate touch and a complex ergonomic curve. The integrated molding makes the front cavity have a good integrity, and the combination with the upper cover and the middle frame also has a high technological level.

▲ FH5s supports replaceable wire design. It comes standard with four high purity single crystal copper silver plated wires and expanded MMCX interface.

replaceable line design can be said to be the standard of "thunder can't move" on headphones of various prices in Feiao. FH5s uses an expanded MMCX interface, and the joints of headphones and matching headphones are marked with left blue and right red. In the accessory, it provides an MMCX quick-release tool, so that users can more easily remove the earphone cord without worrying about breaking the earphone cord with too much force as before.

▲ FH5s matching earphone cable supports replaceable plug design and comes standard with 3.5mm single-ended, 2.5mm balanced and 4.4mm balanced plugs.

FH5s comes standard with a four-strand 120-core high-purity single-crystal copper silver-plated wire. At the same time, the in-line interchangeable audio plug design previously appeared on the higher-priced FD5, and this headphone wire of FH5s also has. It is equipped with a total of 3.5mm single-ended, 2.5mm balanced and 4.4mm balanced plugs. For most users, even if they do not purchase additional earphone wires, the standard earphone wires can meet the needs of accessing various devices. In the storage part, the HB5 leather storage box with good texture is standard, and the blue-brown contrast design has a strong sense of fashion. In addition, the small brush in the accessory can facilitate users to keep the headphones clean daily.

from "1+3" to "2+2"

, as a ring iron headset, has the same four-unit configuration as the previous FH5, but unlike the latter, the FH5s adopts a new acoustic architecture scheme of "2+2", that is, a combination of two moving coil units and two moving iron units.

FH5s is responsible for a 12mm moving coil unit, which is 44% higher than that of FH5 diaphragm. At the same time, the double-sided beryllium ball top + PU suspension diaphragm is plated. The magnetic circuit of the unit is designed with an external magnetic structure. With the strongest N52 magnet at present, the measured magnetic flux reaches 1.5 Tesla. Coupled with the Japanese large black ultra-fine CCAW copper-clad aluminum voice coil, combined with the rear magnetic circuit structure and the precision adjustment of the diaphragm, it has higher ring energy efficiency and lower distortion.

comes from the intermediate frequency part. On FH5s, Feiao replaced the ED moving iron on FH5 with a 6mm fully plated beryllium moving coil. The purpose is obvious. It hopes to use the characteristics of the moving circle in the sound field and sound expression to enhance the overall atmosphere of the music and enhance the charm of the human voice. At the same time, the two moving coils are both beryllium-plated diaphragm, which can form a better echo with the dielectric diaphragm material, making the connection between them smoother. As for the high-frequency part, two Lou's classic TWFK-30017 composite moving iron are responsible. The moving iron is placed in the mouth part, which helps to reduce high-frequency loss and obtain a more extended performance.

▲ Add headphones, a total of 13 pairs of earplug covers of different sizes and types. It is not difficult to find one that suits you. In addition, there are MMCX quick release tools, cleaning brushes and HB5 storage boxes.

While optimizing the unit combination, the structural design of FH5s is also evolving simultaneously. It adopts a standard quad design, and allocates low, medium, high, and extremely high frequency bands in a more reasonable way by calculating the connection of the playback frequencies of each unit. The golden air guide net mentioned in the previous modeling part is an integral part of the FH5s semi-open rear sound cavity design. Its characteristic is that it can quickly release the pressure, relieve the pressure brought by the earphone when listening to music, and make the sound more natural, comfortable and resistant to hearing.

▲ The three-position tuning switch on the earphone corresponds to Senior high school low-frequency frequency response adjustment, allowing users to perform various "micro-operations" on the sound of the earphone ".

In addition to increasing the playability of headphones through replaceable wires and replaceable plugs on the headset line, many of Feiao's headphones also provide tuning functions to meet the personalized needs of listeners. On FH5s, it is not the interchangeable sound guide tube design adopted by FD5 that I have tried before, but uses a three-position tuning switch just like FA9, which was launched earlier and has a higher positioning. There are tuning switches on the left and right headphones of FH5s, which can be adjusted separately. The three-stage switch corresponds to the adjustment of low frequency, intermediate frequency and high frequency respectively. Different from FA9, the latter's three-stage switch has no separate intermediate frequency tuning switch for impedance, low frequency and high frequency respectively, while FH5s has no high and low impedance adjustment and is replaced by intermediate frequency.

tuning switch is very simple. The two gears correspond to ON and OFF respectively. When the three gears are adjusted to OFF and the low, medium and high are adjusted to ON respectively, the corresponding official instructions are balanced tuning, surging bass, pure intermediate frequency and Beautiful treble. Of course, listening friends can also perform tuning combinations other than the above four according to their own needs. The tuning switch is small and cannot be adjusted directly by hand. It needs to be adjusted with the other end of the brush in the accessory. Naturally, there is no problem of misadjustment caused by touch in daily use.

audition experience

first talk about my feelings about wearing FH5s. The four-unit FH5s each weighs about 8.8g. Although it is not particularly light among the many headphones owned by Feiao, it does not put much pressure on the ears when actually worn. This is due to the third-generation ergonomic curve optimization design used in the front cavity I mentioned earlier. It has a high degree of fit with the auricle, and the delicate surface treatment process of the front cavity makes this contact very comfortable. The M-sized equalization sleeve I used has a moderate depth of entering the ear canal, little pressure and good sound insulation. The FH5s standard wire is relatively soft, and it has good stability when worn around the ears. At the same time, the soft touch makes its presence low.

I replaced the plug of the FH5s headphone cable with a 4.4mm balanced plug, and the tuning switch was auditioned under balanced tuning. I have to say that Feiao, who has produced many iron earphones in recent years, has become more and more mature in the adjustment of such products. The "2+2" combination on FH5s has brought about a sound performance that has been reduced to a whole-the connection between the low, medium and high frequencies is very smooth. It happens that I have also listened to some ring-iron earphones of other brands recently. Some of them are not well adjusted. The moving-iron and moving-circle units will have a split sense of hearing at some times and fail to integrate well. Instead, they work independently. They will not feel this way on FH5s.

listening to a few pop music songs, the sound of FH5s is very positive, and the singer's voice is restored in place. The position of the human voice under balanced tuning is centered, with good cohesion, rich details and delicate listening. At the same time, it suppresses the dental sound very well. Even in the music of "the queen of dental sound" Liang Jingru, this part of the performance will not cause trouble to the listener. The thickness of the sound is slightly lacking, especially when listening to some singers with strong voices. The sound style may make some people feel a little "light". I adjusted the earphone to the pure intermediate frequency, the thickness of the human voice will be audible, the position will be further forward, and some charm will be slightly increased. This feeling will be obvious in Cai Dajie's songs. If it is a general pop singer, I think it is good to use balanced tuning.

also auditioned a few low-frequency pop music and instrumental music that specializes in low-frequency testing. Under balanced tuning, the low frequency of FH5s has excellent elasticity, transient and agile, and the strength is satisfactory, but the sense of quantity is relatively ordinary, the dive is not deep enough, and I always feel that I am so bad. When the tuning switch is switched to the surging bass, the low-frequency sense of quantity will be improved to a certain extent, and the atmosphere will become better. At the same time, the part that performs well under balanced tuning will not be affected, and there will be no muddy and bad listening feeling.

FH5s has excellent high-frequency performance, outstanding analytical power, bright and smooth hearing, and has a good extension at extremely high frequencies without harsh feeling. Especially in the music of violin solo, the dynamic interpretation is clean and neat, the listening feeling is completed in one go, and the amount of sound details is very large. If the tuning switch is switched to a beautiful high pitch, it will feel that a "sharpening" filter has been added to the high frequency part, while the density and dynamics will continue to be improved. However, in the interpretation of some extremely high frequencies, it will feel that the burr modification is not so good and the listening feeling is somewhat "sharp". In fact, I think the high frequency of FH5s under balanced tuning has a very high level, which should be enough to meet the requirements of most listeners for high frequency.

in several film soundtracks performed by symphony orchestras, FH5s shows a certain degree of open sound field space. At the same time, the sound field is regular and the positioning of instrumental music is more accurate. It can well restore these movie soundtracks or exciting, or melodious and soothing music scenes, and the atmosphere is relatively in place.

, as the latest work of the main series in the Feiao headset product line, Feiao FH5s has many bright spots. Whether it is from the change of unit configuration to the optimization of acoustic structure, as I said earlier, it is more like a brand new product than the previous FH5, rather than a simple continuation and upgrade. From the previous Feiao positioning higher headphones up and down the function, including the earphone cable with replaceable plug, three-position tuning switch... gives the FH5s more adaptability and sound changes. Compared with the listing price of FH5 in that year, FH5s only symbolically increased by 1 yuan, showing a good price/performance ratio. As a 1699 yuan four-unit iron earphone, FH5s is a good choice for listeners to move forward from a few hundred yuan earphone. It not only has good sound quality, but also has strong playability. Listeners can find the fun of different sound performance under various adjustments. At present, it is during the "618" year of major e-commerce platforms. Listeners who are interested in Feiao FH5s may wish to take this opportunity to start.
