Art can cultivate people's sentiment and interest. Music, like a clear spring, moistens people's hearts. When you are unhappy, music can let you open your heart to her, so as to get rid of the gloomy clouds; When you are hit by the music, you can immerse yourself in it and slowly find out the truth of "the more frustrated, the more brave". Wonderful and magical music always brings people beautiful imagination. The touching music is like a gurgling spring washing the ocean of our hearts. It is music that beautifies our thoughts, enriches our emotions, and wakes up good expectations. Our life needs good sounds. "Let good sounds accompany life easily". On May 20, 2015, a special day, a very emotional but fashionable audio held a small scale internal test conference through WeChat online group, which is O2 smart cloud audio.

It is believed that many people are no strangers to intelligent cloud sound. For example, Xiaozhi, Eel, iFLYTEK, Fruit Shell, etc., which we are familiar with, are all products aimed at playing cloud music. Most of them focus on the concept of intelligence and cloud, ignoring the sound quality problem that should be the most important for sound. A sound that has an intelligent system but focuses on sound quality perception is the smart cloud sound that people really want. It has been some time since O2 Cloud Audio was released from the inside. How can it be unique among many smart audio systems, and how can it achieve outstanding performance? Please follow me to experience it.

It can be seen from the design of the outer package that this is a very emotional product, and the packaging is so exquisite. The main color of the packaging box is white. The open type paper box looks clean and elegant. The front is printed with the design of O2 cloud sound. From the picture, you can roughly understand the appearance of this product.

From the package, it can be clearly seen that the main three functional features of O2 Cloud Audio are music song personality recommendation, voice song ordering and gesture control.

From the side, the junction between the lid and the bottom box of the packaging box is tilted up and down, exposing the orange waist line of the inner box, which is very artistic. From the front, the junction between the lid and the box body is pasted with a seal to ensure that the user verifies whether the items in hand have never been opened. There is a handle made of silver silk cloth at the joint of the box, which is convenient for opening the packaging box. "Loud you want to hear" is the ultimate goal of O2 Cloud Audio, and also the ultimate experience they want to bring to users.

The top side is printed with more detailed product features, scene radio, cloud content, voice interaction, gesture control, three speakers, graphic touch screen and other functional features. This product has a variety of colors for users to choose from: black, white, red, yellow and blue. But at present, I have only seen three kinds of products: black, white and red. What Xiaobian got is a very festive Chinese red.

When we opened the box cover, we saw the main body of the O2 Cloud Audio and a piece of white semi permeable plastic lining. The audio was embedded in a black round foam pad with the same shape, and the package was very stable. There were two accessory boxes on the top of the audio, but only the accessory box on the right side was installed with a power adapter. Careful friends would find that there was a cloth tape at the connection part of the box to pull the box cover, In case of box damage.                                       

The accessories of O2 Cloud Audio are simple to match, with only one power adapter, one manual and one audio body.

              The power adapter of O2 adopts 18V-1.3A DC interface. After being connected to the power supply, you can listen to music while charging.

It is the first time to see such a personalized and exquisite manual, which is folded into a small volume in a round shape, with both pictures and text, and printed in color. It is easy to understand. The manual contains instructions on preparation, music playing, gesture control, etc. It introduces some operation processes in detail, especially the way of gesture control.

O2 Cloud Audio adopts the rare flat circular appearance design, and the front is covered with red special flannelette fabric, which has a fine texture. The grand red color can match all kinds of homes. But this design has two disadvantages: one is the cloth design. It is easy to get dust if it is placed for a long time. If it is dirty, it is not easy to clean it; the other is the cloth design. If it is placed for a long time, it will be easily weathered and cracked or broken by a hook of a hard object? There is no function button on the whole appearance of the O2 Cloud Audio, so how can we operate it? At this time, you will notice that there is a beautiful round mirror in front of the mesh cover, with a diameter of only 4.5mm. This is the special feature of the O2 Cloud Audio. For the first time, it uses the rare touch screen design for audio operation. On the whole, the appearance of this stereo is very simple, elegant and fashionable.

The main body of O2 Cloud Sound is divided into two parts: the upper part is made of flannelette fabric, and the lower part is made of hard bright plastic. Viewed from the side, it is an oval pebble shape with a diameter of 25cm, the height of the highest point is about 12cm, and there is a 30 degree bevel between the main body and the plane, which can make the viewing angle of the LCD screen larger, easy to operate and watch when touching. The middle circle of the round touch screen is decorated with chrome plated strips, which looks elegant and stylish when combined with the whole audio system.

The base of the O2 Cloud Audio is a circular inclined rubber pad, which can achieve a 30 degree tilt between O2 and the plane, so that the center of gravity of the entire audio falls on the base. The rubber pad design can increase the friction of the contact surface, and it is very stable to place. It can be seen from the parameters pasted on the rubber pad of the base that the 8800mAh polymer battery is built into this audio system, which can last for 8 hours when fully charged. When fully charged, the power cord can be disconnected to facilitate mobile listening.

The O2 Cloud Audio adopts the concept of minimalism on the whole, and no function buttons can be seen at the front. For the sake of the overall appearance, the necessary audio switches and power sockets are designed at the back, but the switch design is very inconvenient to operate at the back. Every time I turn on the audio, I have to pull the back of the audio to find the switch button before turning on the audio. An inward concave part can be seen above the base, which is the handle of the O2 cloud sound and is integrated with the bass guide hole.

Basic functions

Press and hold the switch button on the back for 5 seconds to start the machine. When you turn on the touch screen for the first time, you will see that the circular touch screen in the middle is a colorful and very creative startup screen. With a nice startup music, there is an LED breath light under the touch screen. When you turn on the touch screen, it changes from green to blue, flashes, then stays on, and goes out after entering the system. The LED lights displayed in multiple colors are not dazzling at all, but very gentle.

      The O2 Cloud Audio is different from the traditional smart speakers. This audio is not transmitted via Bluetooth, but shares music through wifi. When it is used for the first time, the WiFi signal will be scanned automatically. Click the WIFI signal to be connected, and no mobile phone operation is required. Because a keyboard is built into the touch screen, you can enter the password directly. When the connection is successful, the WIFI signal will be prompted in orange characters. Setting the connection between the O2 Cloud Audio and the WI-FI signal at home is the first step of its power on setting.

After the connection is successful, after entering the system, there is a playback interface in the shape of a vinyl record. You can choose to play music. The middle of the vinyl record will display album pictures and music information. The outer circle of the vinyl record is a circle of orange progress bars to realize the music timeline. The operation of moving up and down can be carried out by sliding up and down, which is very simple.

When O2 Cloud Audio enters standby mode, the weather and time will be displayed on the touch screen, which can also be used as screen saver.

Scene radio

Another highlight of O2 Cloud Audio is that it has its own scene radio station. You can see the selection of radio stations by sliding right. At present, nine radio stations are available to play music of different styles for various use scenarios. Slide to your favorite radio station, and click it to automatically play the music recommended by the radio station, including my favorite songs, which can be directly clicked to cycle. And there is also intelligent recommendation, personalized recommendation of the most suitable music for you, truly "ring you want to hear".

Gesture control

O2 Cloud Audio pursues minimalism. There is no key on the front of the host. Gesture control has become a highlight of O2 design. All operations need to be completed through gesture and screen touch. Although it needs to touch the screen, it is not touch the screen, but gesture operations are carried out on the contact surface of red flannelette. Four touch function keys are built in four directions on the front. When playing music, Tap the upper part of the touch screen for one second to pause/play, and tap twice in a row to collect the song being played; The area on both sides of the touch screen is the volume adjustment area. Tap the left side to reduce the volume, and the right side to increase the volume; There is a long and narrow touch sensing area slightly upward on the touch screen. You can switch between the previous music and the next music by moving your palm.

speech recognition

In addition to touch control, voice control is another highlight of O2 Cloud Audio. The lower end of the touch screen is the sensing area of voice recognition. Touch the voice sensing area and say "Play+song name", or directly say "Hello, little O, play+song name", O2 will automatically recognize and play. For example, if you say "Play Nanshannan" or "Hello, O, play a Nanshannan" to it, it will automatically recognize and play songs

O2 Cloud Audio is also equipped with mobile phone APP client, which is embedded in the touch screen to download QR code. However, the host's own APP currently only supports iOS client, and Android client needs to search on the mobile phone.

Xiao Bian got the Android client APP from the staff in advance to download the QR code. After scanning the QR code, you quickly installed the APP according to the prompts.

After the APP is installed, under the same WIFI, the mobile client can automatically search and successfully bind O2 Cloud Audio, O2 The nine scenes provided are right in front of us. You can control O2 anywhere in your home. You can click on the scenes you like to play songs immediately. The editor found that these nine scenes are not immutable. They will be updated with time, season, holidays and other factors. For example, during the Mid Autumn Festival, the scene of "Happy Mid Autumn Festival" will appear, The subtle changes are enough to see the O2 team's intentions.                                                             

The Android app only supports Douban FM and Netease Cloud Music for the time being, while the ios client supports four online music sources, namely Douban FM, Netease Cloud Music, qq Music and Xiami Music. In comparison, the ios client supports more music sources, and I believe that more music or radio sources will be added in the near future.

But if you want to hear good music from these music players, you need to add a personal account and then bind it. Xiaobian doesn't have a douban account, and you don't want to bother registering. Fortunately, NetEase Cloud Music supports many third-party logins, so I have to listen to songs from NetEase. Even if you don't want to register your account for the same trouble as me, there are also rich songs for you to listen to in the 9 scenes of O2.

In the settings of the Android client, only the connection status of "My O2" and some function introductions and contact information about the O2 team can be seen, but the IOS client can rename the O2 Cloud Audio.

Each music player and radio station provides a lot of online music for users to listen to, which can basically meet the music needs of most people, The interface of the O2 APP is a very conventional playing interface. On the playing interface, you can control the playing. Of course, you can also click to collect your favorite songs. After collecting, you can play them on the "My Collection" radio station on the touch screen of the O2 body.

Life is about being good to yourself and making good voice accompany life easily. O2 Cloud Audio, as a smart audio, takes "extreme simplicity" as its design concept, "a cobblestone like appearance and a touch screen that makes the finishing point ", which makes the appearance design extremely simple, exquisite and novel, with a variety of colors to choose from, and can be skillfully integrated with all kinds of homes. There are no redundant operating buttons all over the body. Massive music can be played through the touch screen, gesture control, voice on demand, WiFi direct connection to the Internet. The specially designed scene radio and personalized music recommendation highlight the" intelligence "of the smart speaker It really reaches "ring you want to hear". The outstanding sound quality performance has brought users a new music experience, which is worthy of being a high-quality wireless Internet audio.

However, everything has two sides, a good side, and of course, there are also shortcomings. A good team should be able to listen to the language of praise, but also listen to the opinions of users. As an emerging force in the smart audio market, O2 Cloud Audio still needs continuous improvement and optimization in many aspects in order to make better products.

1. The power on button is hidden on the back, which is beautiful, but difficult to operate

2. Accelerate the improvement of Android client and increase access to popular music players and radio stations

3. In terms of voice on demand function, the recognition ability needs to be improved. The small version of Mandarin is already very good, but sometimes O2 is difficult to recognize;

4. Sometimes the gesture operation is not very sensitive, I hope to increase the sensitivity later

5. Songs cannot be automatically downloaded and cached. Songs can only be played when there is WIFI. Once there is no network, songs cannot be played

The above are just the areas that I feel need to improve in my personal experience. I hope they can be optimized in the future use experience.
