At present, the WIFI audio on the market gives us the feeling of voice recognition, client operation, and audio in addition to other functions, of course, the most important thing is the sound quality and operation of human nature, the market is basically WIFI audio must pass voice or customer The control of the terminal is good, of course, and of course, it is sometimes possible to liberate the mobile phone, direct selection of songs on the audio, operation, and even change the song through gestures, I believe it will feel more humane. Not long ago, a group of enthusiasts who loved technology and music got together and they excel in many areas: audio, wireless, internet, product design, hardware circuits, mobile development, brand marketing, e-commerce, and launch a product called " O2 Cloud Sound
“O2 Cloud Audio†has a lot of user-friendly features compared to the WIFI audio on the market. For example, he has a built-in touch screen display. You can select songs and other operations through the display screen. The physical keys of traditional WIFI audio are abandoned. The design is changed to a somatosensory control mode. The sound volume is adjusted by touching the sounds left and right. The gestures can be switched between the upper and lower songs by means of a blank gesture.

The side of the outer package introduced the product features. From the introduction of the six features, you can easily understand what features O2 has, and the bottom of the product color, in the color provides six kinds of color options, can provide multiple options, Adapt to different colors for different people 
O2's built-in engineering machine has provided 100 units, each of which identifies its own digital signage. I got this machine to be 000067. The engineering machines are all carefully packaged. I believe the official version will be more careful. 
After opening, "O2 Cloud Audio" has been shown before us. We have to say that the packaging of this premium gift box is very meticulous. The upper and lower parts of the inner packaging are designed with a hard shell, and a frosted transparent ring is added. It is simple and generous. 
On the accessories with a relatively simple, power adapter, manual and engineering experience machine card, the manual describes a number of operating procedures, and contains graphic identification, easy to understand easily to get started 
The power adapter is a DC interface, and the input voltage is 18V. At the same time when the power is connected, it can listen to songs and charge the built-in battery. 
"O2 Cloud Audio" looks very much like a flying saucer. The picture from the official website will make people feel that it is not so big, but after seeing the real thing, it will feel like it's not small. Currently available in six colors, white, black, red, brown, and blue, I currently get a black color. The front design uses a layer of sound-absorbing mesh. The overall appearance is beautiful and people have to think of taking such a net. Whether the design will be easily broken or broken by a hard object, there is still a little worry 
Speaking of "O2 Cloud Audio," one of the highlights is the inlaid circular touch screen, which can be set from a circular touch screen, select songs, etc. The operation is very sensitive, so that the liberation of mobile phones, so you can choose your favorite songs Play, closer to human design.
Around the circular touch screen is a hidden volume addition and subtraction, just put the handle up and down to adjust the volume, and the following is the voice of the open, long press can also open the voice recognition mode, there is no button on the front design The design is based on hidden hand interaction and is also one of the highlights 
"O2 Cloud Speaker" has a three-speaker design and is arranged on the front side with 5W8Ω/15W bass and 4Ω/5W for the high pitched sound unit. It has a HiFi-class independent decoding chip and a Class D digital amplifier. The performance of the voice is commendable 
The design of O2 Cloud Audio discards the previous design of the acoustic boxy. It adopts a circular design. It is beautifully curved and exquisite design. It can be integrated into our home style and can be used as an art. Join us in the home decor 
The back has a perfect arc design, high reflective paint, the entire back did not see the presence of a screw, very careful in the details of the display. However, high-reflective paint, easy to spend, minor scratches can be seen. Built-in 8800mAh lithium battery, can play up to 8 hours of music, standby for 25 hours, when we stop playing music, after a period of time, it will automatically take the standby mode, to achieve the purpose of saving power 
The addition of a larger oval pad on the non-slip mat makes this kind of non-slip effect more noticeable. Even on a slippery table, it can prevent falling damage. The bottom circle sticker simply marked the O2 cloud sound parameters, non-slip design is still more satisfactory place 
The design with a handle on the back can be easily picked up or hung directly on the wall. O2 cloud sound as a whole only one physical button, is to open the key, and next to the power interface, in the design of the interface is too few, for example, you can add audio holes, TF card slot and the like, so you can still use when no network The design of the interface is very little regret 
"O2 cloud audio" with the WIFI audio we have seen in the past, in the appearance of a lot of subversion, circular design even more attractive, abandoned the previous physical button control mode, took a touch of experience control, so simple to control A lot. One of the features of the circular touch screen is that it can abandon the control of the previous mobile phone and directly perform some desired operations on the touch screen. As a WIFI audio, both in design and control, have subverted the design of the past WIFI audio, have to say that this is a very fresh and attractive design
O2 Cloud Audio Client Experience 
In order to make the experience more diversified, a client-side experience was added to facilitate control in the home corner. The current regret is that only the iPhone is supported, and the Android device will only be launched afterwards. The client can download the two-dimensional code on the manual, as long as the O2 cloud audio and mobile phone are kept in the same local area network, open the client will automatically search for connections, a relatively simple connection in the main interface shows the radio, by clicking It will automatically play the radio recommended music, slide to the left to see several options, radio, watercress, NetEase, QQ music and settings. Play by clicking on the music platform you need. The right sidebar shows the currently connected 02. When we have 2 O2 connections, it will be displayed directly. 
"O2 Cloud Audio" currently works with Douban FM, Netease Cloud Music and QQ Music. Personally, it feels a little bit less on the music radio platform, such as the more popular Radio Himalayas, which is hoped to be added later. 
By modifying the settings, you can arbitrarily modify the name of your own O2 cloud audio. Each music and radio station provides a large amount of music for online listening. Although not completely satisfied, daily listening to music is sufficient to meet our requirements. 
Call out the play interface, you can play control, you can also collect, after collection, you can click through the radio "My Favorites" of the circular touch screen to play, this does not want to wake up or in a corner of the room, want to listen to music, Through the mobile client can complete the desired operation
O2 Cloud Sound Operation Experience 
In order to increase multi-mode control, the design of the circular touch screen is added to the O2 cloud audio. When we boot, enter the set WIFI settings, click on the WIFI signal that needs to be connected, built-in keyboard, you can directly enter the password, when the connection is successful WIFI Signal will be prompted with an orange word 
After the connection is successful, you can select the music to play. On the playback interface, use the vinyl record as the appearance, and display the album chart of the song in the middle. You can move up and down by sliding up and down, which is extremely simple. 
Like the right slide, you can see the choice of radio. At present, there are nine radio stations. By sliding to the favorite radio station, you can click to play the recommended music on the radio automatically, including my collection is also included. The collection of songs can be clicked directly to proceed. Loop 
O2 cloud audio support firmware update function, from time to time for firmware optimization, and upgrade methods are also relatively simple, just click Settings to enter the software update, when there is a new version will prompt, click on the update to download. The official also said that the next will add more practical in the O2 cloud audio, such as stock query, smart home, connect WeChat, and other features, which is the follow-up I am more looking forward to the update 
When the music is not played for a period of time, it automatically enters the standby mode, displays the weather and time in the standby mode, and can add some other prompts on the display, such as when the firmware is updated, prompts the firmware update, or the current playback song 
The left and right sides of the circular touch screen are the adjustment of the volume, and the adjustment of the volume can be performed simply by placing the hand flat upwards. This adjustment method is very convenient for individuals. When the “Enable Gesture Change Song†is enabled in the settings, you can use the display light in the middle of the circular touch screen to move up and down the next track. This can be convenient when you are doing something dirty. You can change songs simply by hand gestures. It is also the current WIFI. Audio does not see the control mode 
Above the hand can play the song paused, continuous tap two can also be directly for the song collection, this mode, for sometimes talking to people, afraid of too noisy, you can put your hand above, you can pause, very Convenience 
O2 audio support voice recognition function, just under the circular touch screen, long press a few seconds to call up the voice mode, just speak the name of the song, such as "come" or "small O" can recognize In the test of playing songs, the recognition rate is quite high, and almost all of them can be searched. It also supports the recognition of the weather, and tells you how the weather in the city can automatically play the current weather conditions. There is no way to test and tell jokes. I hope that we can add more voice features to the follow-up.
O2 cloud audio talk about sound quality 
I like music, but I don't have much requirements for sound quality. I feel comfortable with my ears. I have also experienced several WIFI sounds. It gives me the feeling that I lack the bass or the clarity of the treble. O2 cloud sound overall gave me a feeling is very good, in a large area, may not achieve the desired effect in bass, and in a small space, the bass performance is very shocking, treble and midrange are relatively satisfied The place where some of the guitar's crisp sound performance is clear enough, I am very satisfied with this point. O2 cloud sound than some WIFI audio, whether it is sound quality or function is still quite powerful. We hope to add EQ adjustments as soon as possible. Different people have different ways of hearing and can adjust the way they like. It is also a beautiful thing.
Suggest
1: The radio station increases the Himalayas. The station is relatively complete.
2: The operation of the gesture is a bit less sensitive, and it is hoped that the subsequent increase in sensitivity
3: Fewer interfaces, no audio holes, no TF card slot
4: Increase WIFI to store songs offline so that it is convenient to play songs when the network is poor
5: Increase the control of Bluetooth, so that in the absence of a network, playing songs 
to sum up
After more than ten days of O2 cloud sound experience, I feel that this WIFI audio performance in all aspects is very commendable, such as the WIFI audio some novel features, gestures, somatosensory control, touch screen, which are currently WIFI audio less visible, these highlights enough to attract people. The sound quality is within the acceptable range, at least no broken sound, and in the high school low performance are satisfactory, if you want a unique appearance, features, features, easy to operate, I believe O2 cloud audio is a good choice , also looking forward to the follow-up to see the O2 team to launch more useful features on the O2 sound
