In this fast-paced information age, the Internet has gradually changed our living habits. Mildly compressed MP3 audio formats have emerged as the times require. Listening to music is no longer the same as before. You need to go to the audio and video store to buy tapes and find CDs. Music transmission and sharing become simple. At the moment of high development of the Internet, from downloading songs to playing MP3, to playing online directly with mobile phones, It is more convenient to listen to music, but due to the impact of network bandwidth, Wifi transmission speed and other factors, high-quality music is still difficult to popularize. However, with the growing popularity of wireless smart audio market, good audio is also emerging. O2 Cloud Audio is a high-quality wireless Internet audio designed for young people.

  Roger, the founder of O2, said: "It is an important mission of O2 to make good voice accompany life easily.". The design concept of this cloud audio is to achieve simple to extreme operation, design something with personality, texture and better life. O2 has constantly broken through on the way of simplifying complexity, and even subverted the concept of traditional audio. When it comes to subversion, people's expectations of O2 have increased somewhat. Let's review and evaluate O2 cloud audio together, Stick to the feeling of good sound quality.

  Packaging: exquisite packaging design meets the product positioning

  As for the product, I don't agree with excessive packaging design. However, compared with the product value, a high-end smart cloud audio can better reflect the product's temperament, O2 Cloud Audio is exquisite and generous in packaging, which is very consistent with the characteristics of this product's extreme, personality and texture.

When I received O2, I was really surprised. It was a big box. It was heavy to move, and the box was made very beautifully. The big product picture on the top of the front is very striking, and the bottom is "O2 Cloud audio makes you want to listen ", and" personalized recommendation, voice song ordering, gesture control ", which explains the biggest feature of this audio, and makes people have more expectations of O2.

The front side is labeled with the first batch of engineering experience machines. The junction between the box cover and the box body is labeled with a seal. There is a small orange cloth handle in the middle, which can easily pull the box cover open. The junction between the side box cover and the bottom box is designed to tilt, exposing the orange waist line of the inner box, which is very artistic. The gray O2 image icon on the side is also very personalized.

The rear side mainly includes product features, packaging content, product color, product parameters and production information. From this, we can learn that O2 Cloud Audio has six major features: scene radio, voice interaction, three speakers, cloud content, gesture control and round touch screen. It is not easy to integrate these functions into audio, especially gesture control can be said to be more innovative.

  After the box cover is opened, in view of such a huge box cover, the box body connection part has cloth tape to pull the box cover, and the small details are in place. The entire inner box is composed of two plastic linings, the upper and lower, and the middle is a white semi permeable plastic partition, O2 is placed in a round card slot with the same shape, which is stable and elegant. Only one of the two accessory boxes on the top of the audio is installed with a power adapter. It is unknown whether other accessories will be installed in the official version, or just to look good.

The full set of products includes O2 host × 1, power adapter × 1, instruction manual × 1, and the first batch of engineering experience machines × 1. From the product introduction, it can be known that this O2 cloud audio weighs 1.65KG. In order to facilitate use, a handle is designed at the back of it, which can easily lift O2. It is more personalized. The instruction manual and other documents are placed in the slot at the bottom of the box.

The power adapter adopts the design of 18V1.3A, which provides a powerful energy source for O2 and ensures the high performance operation of the audio system. The manual is a circular folded booklet with color printing. The introduction is more detailed, especially for the gesture control mode used in the audio system. The new user can understand how to get started, and the accompanying engineering experience machine thank you letter is also exquisite, It can be seen that the manufacturer is very sincere.

Product: appearance bionic design The details are well done

O2 Cloud Audio adopts a bionic design in appearance. The overall appearance is rounded cobblestone. The small round screen in the middle looks very smart, which can be said to be the finishing touch of the whole design. In terms of workmanship, the handling of various details is not ambiguous, and is very up to standard.

This type of O2 is a black version. The rear is lifted up to make the sound more reasonable. The front is wrapped with a layer of black gauze, which can vaguely see the internal speaker generating unit. The bottom is a black bright surface plastic shell. The circumference of the small round touch screen is decorated with chrome plated strips, which is smart and elegant. From the front, O2 looks like a big letter O.

The bottom circle is a black bright plastic shell with good hand feel. The upper part is specially designed with handles for easy handling. The key switch and power interface are distributed symmetrically below the handle. A thick layer of anti slip pad is set at the middle base to increase friction, prevent easy movement, and reduce resonance. If you look carefully, you will find that there are irregular lines on the anti slip pad, Echoing the cloth pattern above, the parameter label indicates the product model, input voltage and current, capacity of the built-in battery and speaker unit power.

The surface of the host is at an angle of about 30 degrees from the placement surface, which can make the perspective of the LCD screen larger. The rear part of the raised part is also convenient for the operation of the on-off key and the power interface cable. However, because the audio uses 8800mAh built-in power supply, this audio is suitable for the placement space without too many restrictions. The 8-hour full power life can also meet most of the use needs, In terms of audio unit, 2.1 channel system is adopted. There are two 5 watt 4 ohm full frequency speakers on the left and right, and a 15 watt 8 ohm bass unit in the middle. Compared with most similar audio systems, it is robust and powerful. In addition, the back of the audio system is designed with a sound guide hole, which has a better bass effect.

As a stereo, O2 has a clean appearance. The only power key and power interface are hidden in the raised part at the rear. Plug in the power cord, press and hold the ON key to start the machine. The LED status light on the front changes from green to blue, flashes quickly, then stays on, and turns off after entering the system. This LED light is displayed in multiple colors, also hidden under the gauze. When it flashes, it will have a wonderful feeling.

In addition to playing radio programs, O2 can also display the weather on the touch screen. Although the resolution of the round touch screen is not very high, with this interactive portal, many functions that ordinary speakers cannot imagine can be realized. Therefore, O2 has a lot of space in system expansion.

Experience: personalized gesture operation Cloud audio also has good sound quality

With the emergence of more and more intelligent audio systems, there are more and more discussions about such products. In terms of functions, intelligent audio systems have incomparable advantages over traditional audio systems, such as voice recognition operation, network music playing, and intelligent home appliance control. These functions have basically become the standard configuration of intelligent audio systems at present, although there are really few controllable things at present, The sound quality of online music is not so good, and the accuracy of speech recognition needs to be improved, but it represents the future development trend, O2 It also has these functions, and on this basis, it adds the function of gesture control to further the interactive experience.

O2 has its own operating system, which connects to the network through Wifi. Because it has its own touch screen, it saves the trouble of connecting to mobile phone pairing. Select the Wifi to be connected directly on the screen, enter the password, and quickly connect to the network to enter the main play interface. A player that imitates a record player can slide left and right through the touch screen to enter the setting page and radio page, Slide up and down to switch songs, easy to use.

The content of the setting menu is not too much, including Wifi settings The APP downloads QR code, advanced settings, system shutdown, and information about the system version. There are only two options in the advanced settings: gesture song changing and automatic brightness. Other items are also very simple. However, the device information is rich, and you can view the remaining power, working time, software and hardware versions, and other information. Although the current development level of the system still needs to be strengthened, However, it can also be seen that O2 will become more and more powerful in the future.

In terms of actual use, O2 There are few player functions on the touch screen, and most players can only switch songs by sliding up and down. Switching stations also requires clicking from the touch screen radio list. All music playback controls are basically operated by gestures. There are sensors on the top, left and right sides of the speaker, and below the touch screen. When the hands are sensed, The indicator light at the bottom of the touch screen will light up, and the corresponding operation can be realized through the corresponding action, which is very novel and convenient. Of course, you can also search songs or ask about the weather through voice. It is no problem to use without the mobile phone, but the voice recognition rate is slightly low. In addition, O2 can also sense the intensity of light. When you turn off the light in sleep, O2 will automatically reduce the volume gradually, accompanying you to sleep. It's a very user-friendly functional design.

At present, the O2 APP application only supports the IOS system. One audio can be bound to multiple devices, and the audio can be controlled at the same time. There is no need to re bind and unbind. The main interface of the entire APP is relatively simple. You can see that the radio stations of various categories are arranged in square grids, and there are not many categories. Click to enter the player interface. The player function is relatively simple, and there is no playlist, There is no sorting and playing mode, which is a little inconvenient.

To put it simply, O2 APP is actually a radio aggregator, but there are not many accounts that can be added, only Douban FM, Netease Cloud Music QQ Music and Xiami Music, taking Netease Cloud Music as an example, will be displayed in the main menu after adding an account. After entering, you can search music according to different categories, which is very convenient. Other functions include renaming the audio, alarm clock and timing shutdown, but the latter two are not supported in the current version, but now that they are listed in the menu list, It must be open soon.

In terms of sound effect, O2, a 2.1 channel small desktop audio, adopts independent cavity and gradual L-shaped low-frequency enhancement phase inversion technology, HiFi level independent decoding chip, 10 segments of DSP tuning, through full angle sound field design, the 3D sound effect is reproduced. From the actual listening to some classic auditions, the performance of this audio tri band is really good, especially the low-frequency part is strong, powerful, full of sense of volume, diving elastic, and the treble is relatively transparent. Even if the volume is turned to a large volume, there is no broken sound, Some MF voices are naturally full. However, due to the influence of the sound quality of the network audio source, the expressive force of music details will be more or less inadequate, but it is still a good choice for daily music listening.

In fact, after many friends saw the O2 Cloud Audio, their first impression was that the audio was very personalized. Its natural and round shape, coupled with black high-grade special fabric, made the whole machine seamless, classic and simple without losing vitality, elegant, stable and full of style, suitable for a variety of home styles, and its 8-hour endurance can be used in most scenes, Gesture control is more emotional and scientific, while O2's built-in intelligent music recommendation radio pushes music according to habits as the background sound of life, The O2 cloud speaker is just right. One of the shortcomings of this audio system is that the development progress of the APP is still a little slow, and the number of radio programs is also a little low. In addition, the lack of local broadcast function is still a little regrettable. If you can bring your own storage unit or insert an SD card, copy and play the lossless music collected by yourself, I believe it will bring more perfect listening experience.

  epilogue

The era of music cloud has come. As the media of music playing, audio products are also slowly changing, O2 Cloud Audio is undoubtedly one of the more distinctive smart audio products launched recently. Its round cobblestone shape and overall clean design are unforgettable and suitable for a variety of home styles. The innovative gesture operation is elegant and emotional, and the quality of software and hardware in terms of sound quality is also excellent, even under the current situation that the network music code rate is generally low, O2 We still adhere to this sentiment. If we can strengthen the development of application functions and integrate more high-quality network resources, we believe that this smart cloud audio will bring users a more perfect listening experience.
