The JVC M5X that I just played last week won a lot of eyeballs with a domineering appearance. I thought that JVC's Xtreme Xplosives XX series headphones would go wild and not return, but it is obvious that Xtreme Xplosives XX series European and American style headphones are obvious. Just test the water, the HA-S400 portable headset that I got today is back to JVC's traditional simple and beautiful style. No striking decoration and dazzling red headphone cable, no huge size, faded exaggerated appearance, after the S400 can touch us on the sound quality? Let's take a look at the performance of this headset.
Simple design, beautiful style, three-stage folding, light and lightweight
The JVC HS-S400 is a portable headset for the mid-market. It can be seen from the appearance that it is a typical Japanese-style product. The simple and clear design style is not exaggerated, and the design is full of design. The body lines also exude a unique personality. As it stands, such a portable headset is almost the same as other Japanese brands, but in actual use, the S400 does have its own uniqueness.
The overall appearance of the JVC S400 is compact and lightweight, the weight of 145 grams is very light, the whole earphone is black, the black matte material has a low-key texture, and the silver ring decoration on the earphone cover is very technical. Of course, in addition to black, there are sisters’ favorite white 哟~
In terms of portability, the S400 is definitely the ultimate in headphones. It uses a three-stage folding method. Not only can the earphone cover rotate 90 degrees, but the shaft can also be turned inward. Even more so, the head beam of the S400 It is also possible to fold in half along the middle. After the above deformation, the original bulky earphones become only the size of the palm, even if they are inserted into the trouser pocket, it is not cumbersome.
The earphone cover of the S400 adopts the L-shaped design style, which is more personalized than the previous symmetrical design. The earphone cover can be turned outwards as needed, and it is also a good decoration to hang on the neck. The telescopic arm of the earphone is made of thick engineering plastic and feels very firm in hardness. There are two sponge pads on the top of the head beam, but some are hard and comfortable.
In contrast, the S400's earmuffs are much more comfortable, the low-rebound sponge earmuffs are soft, comfortable to wear and have good sound insulation.
The earphone adopts bilateral Y-type wiring, the line length is 1.2 meters, the thick wire material is solid, the visual effect is not so "small and fresh", and the 3.5mm interface can connect most audio equipment.
Carbon nanotube diaphragm analysis high tone true reduction
Although the appearance of JVC HA-S400 did not bring us a lot of surprises, but the configuration is still very "material." The biggest selling point of S400 is the carbon nanotube material earphone diaphragm which adopts JVC's unique patented technology. Compared with ordinary diaphragm, carbon nanotube diaphragm has the characteristics of easy driving, light weight and easy fixing; more importantly, Since the carbon nanotube diaphragm and the wood have the acoustic response characteristics of the pixel, the use of the carbon diaphragm of the earphone makes the sound reproduction more realistic. It is thought that only the high-end products of JVC will be equipped with carbon nanotube diaphragms, and now the technology has already flown into the homes of ordinary people.
S400 has a pair of 30mm neodymium magnet drive unit, the frequency response range is 10 ~ 24000Hz, low frequency to high frequency coverage is in place, 36 ohm impedance is also very good push, mobile phone, PC and tablet can easily push, 104db/1mW sensitivity Also in the standard.
First talk about the audition experience of the whole machine. First of all, the high resolution and intermediate frequency of the JVC HA-S400 have left a deep impression. I thought that the S400 is just a general portable headset, so I didn't expect much from the sound quality. However, after listening to it for a few days, the S400 has been completely opened, and the super-resolution is completely higher than the previous expectations. Whether it is low frequency, medium frequency or high frequency, it is clear and translucent, and the rich details are very vivid. Secondly, the sound of the S400 is natural and true, keeping the true color of the song, without adding too much "MSG", it is a very resistant earphone.
As mentioned above, due to the high resolution of the headphones, the low frequency of the JVC S400 is not the same as the shock of the H5M. The low-frequency elasticity is just right, and the volume is also very strong, but the dive is generally a little bit of water. . However, the details and layering of the low frequency are very strong. Whether it is the humming stream in the accompaniment or the dense drum sound, it can be clearly recognized. Users who are used to the heavy bass may have a feeling of returning to the original.
The IF is the most pleasing place for the S400. The vocals are full and full of texture, the sound is more realistic and emotional, and there is not too much sound and it will not look too dry. The translucent and clear sound is very suitable for listening to women such as Liang Jingru and Zhang Yuhan. The singer's song. When listening to Rihanna's "Rude Boy" song, the singer's magnetic and textured voice was vividly expressed, and the strong rhythm was also extremely shocking. The S400 also has a good performance at high frequencies. The string of the violin is fine and transparent, and the ductility and air feel are just right, sharp but not harsh.
Summary: JVC HA-S400 does not attract users with exaggerated appearance. The simple three-stage folding design is very thoughtful and extremely portable. The sound quality returns to the original, the high resolution of the carbon nanotube diaphragm is far more than the same price product, the true and natural sound allows us to return to the music itself, suitable for listening to pop, classical, NewAge and other styles, like Users of subwoofer rendering may be a bit disappointed, but like drinking espresso, occasionally a cup of tea is not bad.
