two thousand and thirteen On June 25, 2006, Xiaomi Company released a earphone of its own, which was named "Piston Headset" because its model was derived from the piston system of the automobile cylinder, and the final price was 99 yuan. After generations of improvement, the Xiaomi Piston Headset finally released a new third-generation piston headset on March 27, 2015. The new piston emphasizes three major upgrades (acoustic technology, wearing comfort, and appearance design), but its price is still 99 yuan.

  ▼ Unpacking ▼

  The packaging of Xiaomi Piston 3 is not the same as that of Generation 2 in kraft paper, but the same as that of the simple packaging of Generation 2 in white gift box. The square box looks clean and simple.

The back of the packing box is still the same style as Xiaomi. It is still the parameters and instructions of the new piston that we are familiar with.

There is a round plastic sticker on the side of the box. Gently remove the plastic sticker to open the packaging box.

The package box was opened in four directions. Like the previous piston earphone, the earphone was packed in the middle like a blooming flower. The entire outer package was designed with ingenious origami.

When the outer package is unfolded, we can see that the concise instructions for use are printed on the package, and we can simply understand that the shell is a manual for use. Each side is the introduction of the settings of each button of the headset, the storage of the headset, and the graphic introduction of how to replace the earplug sleeve. It not only reduces the cost and improves the overall texture of the product, but also can understand its functions and instructions. It really kills two birds with one stone. This is a product that people are reluctant to throw away even the box.

The packing box is completely opened, and there is a layer of plastic transparent bag inside to wrap the headset box.

Tear off the transparent plastic bag, use the exquisite box packaging, and use the large "mi" logo, which has a metallic texture and is high-end and grand.

The design of the back of the headphone case is the same as the old packaging

Gently open the earphone box, and our earphones lie quietly in a silicone receiver.

The new Xiaomi Piston Headset has been comprehensively improved in appearance and sound quality, and won the "Oscar" in the industrial design industry - 2015 Red Dot Award, The new piston earphones are still designed by the Xiaomi ecological chain enterprise 1MORE Design. As early as February this year, Canada Unicom announced that it had obtained a new round of financing, introducing IDG Capital, GGV Jiyuan Capital and Singapore National Sovereign Fund GIC.

The earphone is installed on a wire winder made of silica gel, which can not only wind the wire, but also fix the earphone cavity, Compared with the old version of the winder, the color of the new version is relatively light.

Take out the earphone. At the bottom of the winder, in addition to the original earplug, there are three sizes of silicone earplug sleeves XS, S and L as gifts to meet the needs of users with different ear canal sizes.

The new piston uses a 3.5mm gold plated plug, The metal components have very fine CD metal wire drawing lines. The gold-plated plug can prevent the oxidation of the contact surface of the plug, and reduce the wear of the headset in the process of plugging Reduce signal transmission loss, Give us more real enjoyment of sound quality; in addition There is a QR code and Xiaomi LOGO on the label, Scanning the QR code can check whether the headset is genuine or not, and you can also download the computer software.

In terms of online control, the design of the wire controller is the same as that of the past, which is still cylindrical. There is a microphone tapping hole on the back of the wire controller, and the shell of the wire controller is also beautiful metal brushed texture (CD texture).

The wire control is designed on the right voice cavity wire. The keys are three key type, which are side by side. It can be used with Xiaomi mobile phones. The functions of the keys can be customized. You can use them as you want.

The wire from the 3.5mm plug to the wire splitter is wrapped with Kevlar material, and the wire from the fork to the acoustic cavity is made of TPE material. This design will bring better strength to the wire, increase durability, and effectively prevent stethoscope effect.

In terms of wires for the new piston earphones, the tough and tensile Kevlar bulletproof fiber is still used as the earphone core wire, effectively protecting the earphone cable and extending its service life. At the same time, in order to solve the problem that the headphone cable is easy to wind and knot, the surface of the wire material is made of braided wire, so that the headphone cable remains flexible and not easy to wind. The use of TPE surface for near ear wire can reduce the friction with clothes and reduce the "stethoscope effect".

In order to wear comfortably, the new piston adopts a double bevel design at the connection between the ear plug and the tail pipe, and no matter how long you wear it, you will not feel ear pain, In addition, the earphone has clearly marked the left and right wearing modes, and the remote control is also designed on the right ear branch line.

In order to further improve the sound quality, the new Xiaomi Piston Headset uses a metal composite diaphragm designed as a "sandwich structure". The two outer layers are made of PET material, and the middle layer is made of metal material, bringing more extended treble details. At the same time, PET material has the characteristics of softness and elasticity, which also greatly ensures the mellow midrange and strong bass effect.

The new Xiaomi Piston Headset is starry sky Titanium, The edge of the rear cover and the tail pipe adopt the metal drawing process, Under the natural light, there is a little purplish black gray with metallic luster, more like the reflection of CD, The surface is anodized and tested by alcohol, abrasion and abrasion resistance, which can improve the abrasion resistance and corrosion resistance of the metal surface.

  The new Xiaomi Piston Headset uses the third-generation balanced damping system. Compared with the second-generation straight through balanced damping system, the size and length of the front and rear sound cavities of the third-generation balanced damping system have been measured from the size of the sound channel aperture to the length. It forms a balanced damping system with the built-in precision damping materials, making listening transparent and natural. Moreover, the effect of the new piston stethoscope is well controlled. The overall weight is 11g, which belongs to a relatively light level and will not burden the ears; Sound insulation effect is also excellent; The impedance of 32 Ω is easy to push in Xiaomi Note; After the HiFi is turned on, the spatial sense of sound can be restored, and the level is relatively clear.

▼ summary ▼

The three perfect upgrades of the new Xiaomi Piston - the overall continuation of the minimalist design style, won the "Oscar" in the industrial design industry - 2015 Red Dot Award; The exclusive patented "sandwich diaphragm" metal composite technology, "spiral trachea" technology and the third generation balanced damping system make the sound quality better improved; Comfort upgrade, ergonomic design, double bevel design, make wearing more comfortable. However, with such a huge increase, the price is still 99 yuan, which is more worth starting with than the first and second generation pistons.
