JVC's earplugs and wood are inextricably linked. As early as 2007, they introduced the wooden diaphragm earplugs FX500, and three years later brought the FX700 with a thinner diaphragm. At the end of last year, JVC released a new wooden diaphragm flagship earphone FX800 in China. In terms of performance, the wooden diaphragm and wooden cavity ensure the consistency of acoustic response, and the sound is higher in reduction degree than the general dynamic earplugs. What effect will it have on the FX800?
Before JVC has tried two kinds of wooden earplugs, FX500 and FX700, FX800 has the same appearance as FX700 in both the box and the earphone, and because there is no FX800 related information on JVC official website in Japan, many friends suspect that FX800 is another FX700 in China. The vest version, after all, FX800 is nearly 1,000 yuan. In fact, it is not uncommon for electronic products to be launched domestically or only in China. JVC Hong Kong official website and domestic agent merchandise official website also have FX800 information, and its identity can be assured.
In terms of performance, JVC FX800 can be regarded as a line-changing version of FX700. The wire is changed to 4N-OFC oxygen-free copper (oxygen-free copper with a purity of 99.998%), and a layer of aluminum is used for signal shielding. This selling point FX800 will also replace the transparent plastic with the covered wire, but unfortunately it is still not possible to change the line. According to the official statement, although the FX800 uses a wooden diaphragm with a diameter of 10mm like the FX700, the area of ​​the cotton structure has increased by 27%, and whether the sound quality has improved is discussed later.
A pair of dark brown wooden cavities are low-key and gorgeous. The wood has the characteristics of warm and thick tone. It is generally used in high-end HiFi speakers or top headphones. It is like the Tianlong D7100 with a price of nearly 10,000 yuan and the Iron Triangle W5000 with more than 6,000. With a wooden casing, JVC's FX800 is still very costly in terms of materials.
The FX800's wooden case has been specially polished to show that it still retains the grain of the wood. There is a circle of silver metal ring on the outside of the earplug. The golden breathable filter can be seen through the decorative ring. The headphone wire and the cavity joint are the same. It is made of metal and has a very reliable reliability. The outlet of the earplug wire is also wrapped with a piece of black rubber to improve the bending resistance of the wire.
The earplugs are equipped with S, M, and L pairs of different sizes of silicone earplugs, and two pairs of S and M sponge sleeves are attached. In comparison, the sponge cover has better sound insulation effect.
The headphone cable is 1.2m long and adopts the Y-type split line mode. The splitter has a type designation. The 3.5mm L-type interface can be compatible with most playback devices.
The FX800 uses a 10mm diameter wooden diaphragm unit with a frequency response range of 6Hz to 26KHz, a sensitivity of 106dB, an impedance of 16 ohms and a power of 200mW. At the FX800 conference, the sound of the wooden diaphragm was displayed. The wood was made of high quality birch, and the thickness of the wooden diaphragm was only 8 microns (0.08mm plus or minus 0.01mm), which is comparable to the thickness of the hair. High, low yield, which in turn increases production costs.
Overall, the FX800 is a style of restrained warm earplugs. The sense of hearing is natural and emotional. The analysis is not as high as the three-unit dynamic FXZ200 that was previously auditioned, but still has its own characteristics. Compared with the low frequency of the FXZ200, the FX800 has no special directivity on the tri-band. The tone is naturally fresh and the resolution is not as good as that of the FXZ200. However, the frequency range of 6Hz~26000Hz does bring a strong sense of space, and the sound field is wide and knotted. The image is in place and the stereo is very strong. It is a pleasure to listen to the Live scene.
Some colleagues have the Etome single-unit moving iron HF3 and JVC FX800 at hand. There is no need for a dynamic moving coil, but after listening to these two plugs, they still talk about their characteristics. After the earphones HF3 in the ear, you can feel the iron smell of the moving iron earplugs. The powerful analysis will peel off the sound layer. The initial listening feels sharp, but the single-unit moving iron is missing and narrow in the sound field. The frequency band is also fully exposed, the sense of space is very suppressed, the vocal sounds become distorted due to over-emphasis on analysis, the tone is cold and lacks emotion, the low-frequency presence is weak, and the so-called "clear oligo-smooth" taste in the colleague's mouth is fulfilled. Relatively speaking, the FX800 is less powerful than HF3 in terms of resolution, but it completely surpasses HF3 in the layering and dynamic range of the timbre. The vocals are full and full of emotions, the high frequency is clear and clear, the low frequency is very full, and the rebound and transient response are very good. Fast, just dive is not enough, in addition to a certain rendering on the low frequency, the overall sound quality of the FX800 is natural, it is a very earphones.
The audition selected "Touch Grassland 2", "Guangdong Listening to Good Listening", "I hope people long", "HiFi Age V" and Other vocal saliva dishes and Nakajima Mika "Sound of Music", SENS "Sound.Earth.Nature. Spirit, Joe Hisaishi, featured "The Best Collection of JOE HISAISHI". There is no special directivity on the FX800 tri-band. The mid-range and vocal sounds are natural. It sounds like a kind of bright feeling. It feels very transparent. When I listen to Gabriel and sing "Moon Spring", the female voice is full and full. The sweet warmth is pleasant. The separation between the tri-bands is high, but the connection is also very natural. It is not the one-size-fits-all separation feeling of the moving iron earplugs. The vocals and accompaniments have a certain blend but the positioning is accurate, the vocal position is in the middle, and there is no such thing as the front ear. The sense of front embossing will not bring about the distant sense of alienation. Listen to the HiFi slogan.
The natural restoration of the tone is a feature of the FX800. The advantages and disadvantages are also obvious. After listening to other earphones and listening to the FX800, you will find that the FX800 has a good sense of volume and rebound at low frequencies, and the transient response is fast, and the rhythm is just right. The disadvantage is that the low frequency is slightly turbid and not transparent enough, and the dive is not deep enough. The high-frequency is bright and transparent, and it also has good ductility. There is a violin solo in the middle of SENS's "Rain". The rapid transition between the strings brings a strong sense of sprint, and the FX800 is a good expression of this tension. The atmosphere, and the reverberation of the violin when the bow is closed, is endless and extensible.
In the dynamic earplugs, the FX800 achieves the highest level of quality in both its workmanship and sound quality. The warmth and sound of the wooden cavity and diaphragm are pleasant to the sound, and the fresh and natural sound quality is not overly audible and introverted. Although the analysis is not as good as the previous three-unit dynamic FXZ200, the wide range and excellent intermediate frequency performance are still eye-catching. The sound quality of the wooden diaphragm can be affirmed, and the 16-ohm impedance mobile phone can also be easily promoted by mobile devices. The current listing price of the FX800 is at 2980. Compared with the FX700, the FX800 after changing the line and strengthening the diaphragm is nearly a thousand dollars. After all, this price has already had a competitor like UE900, and it is worth noting that it is worthwhile.
