The four-unit mixed earplug FH5 experience evaluation with smooth connection and melodious rhyme.

is a small group in the Hi-Fi circle, it is very lively. There are also many technology hotspots in this small circle. Take the popular earplug products, from the initial multi-unit stacking to the "ring iron" hybrid earplugs that have emerged in recent years., Are very creative. Many manufacturers have already invested a lot of energy in research and development in the field of multi-unit earplugs. As the most popular domestic audio manufacturer, Feiao did not launch its first round-iron hybrid earplug product FH1 until last year. It seems that the "heat" of the "round-iron" structure earplugs is somewhat late. However, in June this year, Feiao released its fourth round-iron hybrid earplug FH5.

, there is no doubt that Feiao has made great achievements in the audio field. Among its products, players, decoders and earplugs have a good reputation, but the reaction on earplugs with "ring iron" hybrid structure is relatively slow. However, with the emergence of FH5, this situation should be changed. As this year's new product, the flagship positioning of FH5 can be seen from the selling price. This is a more high-end product launched after last year's popular FH1, with the aim of conquering those high-end enthusiasts.

rich and varied accessories

Feiao products is not only due to our well-known keywords such as quality control, appearance design, and high cost performance. The precise positioning and rich and diverse configurations of each product are also "secret weapons" that impress consumers ". Feiao is good at enriching its accessories according to the positioning of its products. Even for entry-level products, Feiao's accessories are always so complete, let alone FH5, a flagship,.

unpacking FH5, what may shock you most is the attached 12 pairs of earplug covers (one of which is already worn on headphones) with different timbre experiences. Feiao did not print the functions of different earplug covers on the instructions this time, but directly presented them on the packaging, which is also convenient for users. Four different silicone sleeves show Feiao's grasp of details for different timbres, and can also better reflect the professionalism of this product.

considering various usage scenarios, the portable storage methods provided by Feiao on FH5 this time are divided into soft bags and hard boxes. This is the first time that I have seen headphones with two storage devices.

is this cleaning brush, which is used to clean dust and earwax near the earplug guide sound control.

precision workmanship and appearance

appearance is inspired by acoustic streamline design. Under the layer-by-layer creation of designers, the designed shape is the grain formed after the stream flows. The body is concave and convex, just like rolling hills, forming ravines after countless small rivers flow through. Water drops drip, ripples; converge into a river, flowing endlessly.

FH5 is a few real objects in earplugs that are better than renderings. Although the entire earplug is a special-shaped design, there is no visual gap. The all-metal cavity is a test of the manufacturer's manufacturing level in the production of earplugs, and the part of the manufacturing process has always been a proud part. The fully CNC machining and cutting cavity has also been manually selected and polished, and then processed by multiple processes such as sandblasting and anodizing.

a stable and comfortable wear

Since the plug-in interface of FH5 is above the earplug cavity, it is worn around the ear. This attached wire has a longer part to assist the ear, which can be suitable for a variety of face shapes. The arc of the original wire around the ear is larger, which can better adjust the firmness of the earplug on the ear.

FH5 is still very comfortable when worn normally. In fact, in the wearing of most people, the cavity of FH5 does not completely fit the ear cavity, the thickness of the earplug cavity is just right, and the weight of the earplug is light. The weight of the entire earplug is borne by the fit of the part around the ear and the lower earwheel. Therefore, in order to strengthen comfortable wearing, users should choose a sleeve suitable for their ear canal size in the selection of earplug sleeve size.

the reinforced replaceable line design, cavity and unit re-evolution

FH5 cavity adopts MMCX pluggable design, and the wire body adopts 3.5mm four strands of 6N single crystal copper silver plated high specification wire: LC-3.5B. The wire can effectively reduce distortion and loss in signal transmission, while the outer cover is made of transparent and environmentally friendly TPU material. The wire is designed with double strands, which is slightly thicker, but it looks very Hi-Fi.

FH5 and the special-shaped design make the cavity stronger. With the high rigidity of the metal material, the whole cavity has a good effect in eliminating sound resonance standing waves. The vent hole in the middle of the cavity allows the FH5 moving coil unit to obtain more ventilation. The entire earplug cavity cleverly combines wearing and acoustics, which is commendable.

careful observation of the sound guide tube, we can see that FH5 adopts a three-frequency design, in order to better present clean and low crosstalk sound. Among them, the medium and high frequency are driven by three moving iron units of Lou's, and the low frequency is output by a polymer with a diameter of 10mm conforming to the membrane strong magnetic unit. The sound tube is designed with a vortex structure and uses the sound wave conduction characteristics to filter the excess medium and high frequency information of the moving coil to ensure the cleanliness of the low frequency.

The multi-unit connection is smooth and the sound is melodious.

Nowadays, multi-unit ring iron hybrid earplugs are nothing new. Using the advantages of moving ring unit and moving iron unit to complement each other in sound experience, accurate frequency division and detailed tuning are needed to achieve this better.

in terms of ease of pushing, FH5 is not difficult to push, absolutely most portable devices can push, even mobile phones can push FH5 "in a good way". As far as sound style is concerned, FH5 neutral and clean sound is very convenient to match with portable front ends with different styles to achieve users' favorite sounds. FH5 has a more outstanding sound experience with a larger thrust front end like Feiao X7Mark II. The sound field scale, image formation and resolution of the entire earplug have been greatly improved, and the two-stage extension of the sound is obviously more open. It can be seen that it takes an advanced level of player equipment to completely push FH5 well.

, in terms of hearing feeling, FH5 is different from many ring iron earplugs in that it does not specially emphasize the taste of ring iron sound characteristics, but achieves a new height in the smoothness of three frequencies. This is also the unique efforts of Feiao FH series. People will feel "good" when wearing this earplug, which is also the most touching thing for the author. Due to the reason, the part of FH5 in the medium and high frequency has been strengthened naturally, thus better rendering the hearing feeling of the medium frequency sound, and the loose dynamic range of the medium frequency will not make the earplug in the medium and high frequency part full of "iron flavor". This loose and natural intermediate frequency forms a better contrast with FH5 full of grainy high frequency, so as to obtain a better sense of hearing between high frequency and intermediate frequency. In terms of low frequency, FH5 has sufficient low frequency sense, and its high resolution makes the level sense and image of low frequency very clear. It is worth mentioning that the low-frequency transient is not inferior to the medium and high frequency using the moving iron unit, which is enough to see how outstanding the quality of this moving coil unit is.

the vocal part, according to the sound tone of FH5, with the medium frequency loose dyeing, the vocal experience of FH5 will be slightly younger and sweet. The high resolution of the moving iron unit makes the sound feel a little grainy, from the details of the true false sound to the detailed ventilation sound, it is easier to be heard by people, and the part of the dental sound FH5 is processed very well, even some music with low recording quality will not have obvious dental sound.

summary


Feiao has been trying to make "ring iron" mixed earplugs "nice since FH1". After nearly 8 years of development, there are still many manufacturers who can't even do the basic frequency division well, let alone whether it sounds good. On FH5, we saw Feiao's mature ID design and smooth connection sound. The relatively loose and rich medium and high frequency dynamics make this earplug crowded with high quality and can adapt to a very wide range of music. This is one of the few "nice" ring iron earplugs on the market. I believe FH5 can bring you unexpected surprises.

PS:FH5 is scheduled to go on sale on June 29, and the price is about 1698 yuan. It is said that there are surprises for the initial listing.
