Bluetooth portable speakers have now become a very important class of audio and video products in the market, but it is not easy to select a suitable speaker from a large number of product models. In recent years, wireless audio has become a popular peripheral accessory of mobile phones. One of the most obvious phenomena is that people keep their mobile phones on their hands all day long. After work, the use time of mobile phones has exceeded that of PC devices. However, due to the size limitation of mobile phones, large audio units cannot be added, so the sound quality is often unsatisfactory.

Nowadays, the manufacturing threshold of Bluetooth audio is very low. There are hundreds of pages in a treasure search. Although Bluetooth has great pressure on transmitting lossless files, Bluetooth audio has won a lot of favor due to its excellent portability and wireless characteristics. In the face of tens to hundreds of prices, appearance has become an important factor for us to choose it.

As a mature company, it seems logical for Xiaomi to re deploy Bluetooth speakers this time. Xiaomi launched its own portable Bluetooth audio system at the Xiaomi 4C launch conference, which is compact in size and continues the traditional "cost performance" mode in terms of price. Xiaomi Pocket Audio has a full metal shell body, which is small and portable, only the size of a pencil box, has a variety of colors, supports Bluetooth, Aux in, SD card and other connection methods, and is known as "a good speaker that can fit into your pocket". Now, let's take you to experience it.

Now there are two kinds of wireless speakers on the market, one of which focuses on high fidelity sound quality, but the disadvantages are also obvious, large and heavy, and low portability. The other is to focus on portability. In order to meet the needs of carrying out, it has high endurance and loud volume. Xiaomi pocket audio belongs to the latter, which is made of all metal body, and actually only has a pencil box Size, no pressure with one hand . And its surface Sand blasting, radium carving and secondary anodizing coloring are adopted, which makes it feel very textured.

Xiaomi pocket stereo is only the size of a pencil box. Its body is 168 x 24.5 x 58 mm in three dimensions, and it is as light as 270 grams. It is small enough to be hidden in your pants pocket. It can last for 8 hours after a full charge.

In addition to its beautiful appearance and portable body, as a new favorite of music enthusiasts, Xiaomi Bluetooth speakers are also powerful in functions. They not only have excellent sound quality, but also support many music playing modes, including Bluetooth, Aux in audio cable, Micro SD card, hands-free call, etc. They can be paired with mobile phones, tablets, televisions, laptops, allowing you to listen to more good music as you want. The Xiaomi Bluetooth speaker supports up to 32GB Micro SD card, which can store nearly 10000 songs. It has a built-in microphone function. When there is an incoming call, the music will automatically pause. Just press the play key gently to switch to the hands-free call mode.

The Xiaomi Bluetooth speaker is equipped with two sound generating units. It uses dual 36mm speakers with a power of 3W. The data is hard to handle. It uses Nd-Fe-B strong magnets, Ferrotec FRM4005 magnetic fluid cooling technology, and black anodized aluminum alloy diaphragm to make the sound quality more full and moving, and its coverage is comparable to that of HiFi audio, Its sound penetration is very strong in outdoor environment.

In order to restore the details of music and create a better sound with a stronger sense of scene, Xiaomi Bluetooth speakers use a more beautiful and reliable "two-color injection molding" integrated bass radiator and a rice grain array TPU overhang, which are more beautiful than traditional adhesive. The sound vibration damping is more coherent, and the stability of the sound is also enhanced. High, middle and low voices are excellent.

Although speakers should focus on playing, in this era, if a Bluetooth speaker can only play songs after pairing, it is really embarrassing to greet people. The Xiaomi Bluetooth speaker is also rich in functions, which can be seen from its appearance: the buttons on one side of the speaker support pause/play, track switching and voice broadcast power, while the other side provides micro USB, AUX and TF card interfaces, as well as a microphone. There are sound effects or voice prompts for pairing, switching and other operations. When you press the power button, a soft girl will remind you: "The current power is about 100 × ×%". Compared with some electronic sounds, it is totally a blessing for otaku.

The key to Bluetooth speakers is sound quality. The audio chip of the Xiaomi Bluetooth speaker uses Avnera AV3102. According to the official instructions, "the voice adjustment is delicate and balanced. It supports up to 19 segments of PEQ adjustment and 12 segments of amplitude limiting DRC. With the aluminum alloy diaphragm, higher sound pressure can be obtained, and the treble is more transparent. Even when the power is insufficient and the volume is maximum, the middle and high frequencies can still be clear and clean." At the same time, the two 36mm sound generating units on the left and right and the bass radiator in the center "make the sound quality more attractive, the coverage can be comparable to HiFi sound, and its sound is also very penetrating in the outdoor environment." However, is the fact as beautiful as the copy? Let's actually test it.

Sound quality experience:

Feng Xiyu - A Little Love

A very healing sweet female voice, through the song, we seem to be able to feel the autumn afternoon sun through the withered leaves shadow, the girl with short hair wearing the gauze dress was blown by the breeze to sing a sincere and delicate love song.

The piano sound at the beginning of the song is very clear, elastic and crisp. With the development of the song, the performance of one voice seems a little unsatisfactory. We can easily feel the characteristics of sound quality, with moderate and high pitch.

One Republic-《Apologize》

This is one of the representative works of Cook's favorite band, who performed at the latest Apple release conference. This song can be called an enduring song, with a strong sense of rhythm, and the singer's emotional expression is just right, which is very suitable for testing headphones.

The performance of this song is basically familiar, no matter the voice interpretation of the most advanced singer, the position of the accompaniment, the distance of the instrument are relatively clear, and the strength and rhythm of the bass are relatively strong. It gives people the feeling that the bass is full, the voice is rich, and the volume is large. You can feel the obvious bass vibration when holding it in your hand. Pop music and dance music are very good. The sound is very dynamic, making people unconsciously get up.

Xiaomi Pocket Audio is subject to the pressure of volume and cost, so it is impossible to have heavyweight feedback. However, after trying several pop music songs, the performance of the pocket audio still satisfied Xiaobian. However, the performance of the voice is not so ideal. You'd better find another place to listen to classical music. If you are not a music enthusiast and are not very sensitive to audio, then this speaker is very suitable for you. The portable size and good playing ability make it a pleasant thing to be a bedside stereo.
