Dynamic coils and moving iron earplugs have always been distinct, dynamic dynamics and high iron analysis, but this customary law was broken in 2011. When JVC released the world's first dual-unit dynamic earphones FXT90, the FXT90 with the multi-moving unit as a selling point created a new earplug category, FXT90 has both high dynamics and high resolution, plus a cheaper price than moving iron earplugs. Become a cost-effective plug. A year later, JVC went further in the field of multi-unit dynamic earplugs, and launched the three-unit dynamic ring twin FXZ100/FXZ200, breaking the three-unit pattern of moving coil earplugs.
The FXZ100/FXZ200 is a new product released by JVC in Japan in November 2012. The two earphones are almost identical in design and construction. They are all made up of a 8.8mm woofer and a pair of 5.8mm mid-high-pitched units. The main difference is in the material. Embodiment: FXZ100 is an aluminum alloy cavity shell and ordinary wire, while FXZ200 is replaced by brass shell and OFC silver plated wire, the price is naturally rising.
Due to technical innovation, JVC FXZ200 is also a rewarded product of Japan's "VGP2013 Technology Appreciation" (remember that FXT90 also won this award last year). The FXZ200 also continues the quintessence of the FXT900. The brown translucent acrylic cavity allows the internal components of the earbud to be looming. The subwoofer unit is added to the original Twin System Unit unit. The cylinder protruding from the rear half of the FXZ200 is not. Hard to understand, this also makes the volume twice as large as the FXT90.
The overall appearance of the earplugs is low-key and restrained, and the sounding unit in the earplugs of the translucent shell is unobstructed, and the professional style is full. Concentric circles and brushed embellishments give a metallic feel, while the other side uses red and blue to indicate the L/R prompt. The FXZ200 is an in-ear earphone, and the tilted earplug catheter allows the sound to penetrate deeper into the ear, avoiding ambient sound interference.
Unfortunately, the JVC FXZ200 still does not support changing the line. Friends who play the wire do not have to count on it. The earphone cord is 1.2 meters long and adopts the Y-shaped branching method. The splitter is somewhat exaggerated. It is thought to be a wire-controlled microphone. Wrapped in soft rubber at the end of the thread, it is more resistant to folding than the normal earphone cord. In addition, the FXZ200 also comes with a small clip that can be worn on the clothes.
Remove the silicone earplug sleeve on the FXZ200 to see the transparent tube and filter. The earplugs are available in S, M, and L. The accessories are not defective. The package is provided with a portable storage bag and a wire take-up.
The earplugs are quite comfortable to wear, and the size of the earphones used by the M model is just right, but the sound insulation effect is still a little worse than the sponge sleeve. If you have the conditions, you can DIY to make a sponge cover. The FXZ200 cavity is much larger than the general in-ear earphones, resulting in a large part of the earplugs protruding. The beauty index is not very high. From the front, it seems that there is a pair of golden ornaments on the ears.
JVC FXZ200 has a maximum input power of 150mW, a sensitivity of 96dB/1mW, and an impedance of 16 ohms. It can be easily pushed by mobile phones and players. The frequency response range is from 5Hz to 26000Hz. The low frequency and high frequency are wider than the general earplugs. The FXZ200 compensates for the lack of FXT90 bass in terms of function. The structure is the enhanced version of FXT90. The front part of the earplug is a pair of side-by-side 5.8mm neodymium magnet units, which are responsible for the middle and high frequency parts. There are some differences between the two: the upper unit is The carbon nanotube diaphragm and the lower unit are carbon fiber diaphragms. The rear part of the earplug is occupied by a 8.8mm diameter subwoofer unit, and the woofer is wrapped by a gold outer casing. The Kelton-type speaker is designed to deliver sound waves to the earplug duct through a 30mm long draft tube. Another function of the catheter is to attenuate audio above 100 Hz to make the bass sink.
The front-end equipment selected the iPod Touch and the Sony DEJ-100 CD player that are used daily by Xiaobian. The sound source includes Liang Bangyan’s "Twelve Kingdoms" OST "Twelve Dreams", Lady Gaga "Born this way", Adele" Live At The Royal Albert Hall, "The Rose" by Hand Island, and other regular albums in 320kbps MP3 and CD Audio.
Xiaobian once sighed when I tried to listen to FXT90. If the volume of the bass can be strengthened, this time the FXZ200 has added a separate woofer, but it is afraid that the bass will be over-the-top. Fortunately, the FXZ200 is not the kind after the audition. The strong bass sound is heard, the tri-band level is clear, the low frequency is thick and not exaggerated, and the sound is clear and natural.
Compared with the strong iron flavor of UE900, JVC FXZ200 tastes a lot lighter, and the dynamic material also determines that it can't reach the UE900's fidelity resolution, but it still has the top level in the dynamic earplugs. . The intermediate frequency and high frequency are relatively advanced in space, the low frequency positioning is far, the lateral stretch of the sound field is good, the vertical space is slightly suppressed, and some cannot be opened.
When listening to the gorgeous folk music dance music of "National ~ Oriental Li Yun", the sound is full, the sound of silk bamboo turns and has strength, and the instruments of Guzheng, Pelican, Di, Xiao, Drum, etc. have high separation degree, and also have both Good ductility and rich details, the sound of the string reverberation around the ear is endless, bringing a very pleasant sense of hearing, and listening to this piece with the apple earbuds is the kind of turbid feeling, 5Hz ~ 26000Hz ultra-high frequency range The benefits are evident. In the prelude, the powerful drums are very strong, and the elasticity and transient response are also very fast. The only drawback is that the dive is not deep enough, and some of them are still unsatisfactory. As mentioned earlier, there are certain limitations in the FXZ200 sound field, such as the lack of gas in the performance of Adele "Live At The Royal Albert Hall".
The FXZ200 restores the reality in terms of intermediate frequency and vocals. There is not much music to add. The overall listening is warmer. The female voice is sweet and full of emotions. The male voice is thick and clear, and the clear and transparent sound is not particularly biased for male and female voices. The fusion of background and vocals is just right, the intermediate frequency will not be too far ahead, and will not be submerged in the background music full of sense.
Overall, the JVC FXZ200 is a very balanced earphone with no obvious defects in sound quality. It has a resolution close to multi-unit moving iron earplugs and a wide frequency response range, and does not pick up equipment, including mobile phones. Can be very good. At present, JVC FXZ200 has just been listed for sale at around 2000. Xiaobian thinks that it is somewhat expensive. After all, this price can already buy multi-unit moving iron. Users with higher sound quality can try the taste of multi-unit moving coil.
Wireless Router
The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.
Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
