People who understand music understand life better.

                                When you are happy, music is sugar, melting your heart;

                                    When you are sad, music is medicine to heal your wounds.

        We live in a time of chaos and noise, and we can't stop fighting for our dreams, wealth and status every day. The pressure is like a mountain, and it can push people to the brink of collapse at any time. At this moment, we might as well stop for a moment, brew a pot of tea, open a song, taste the tea, listen to the exquisite feelings brought by the music, chew the joys, sorrows, and various forms of life in the lines, and purify the messy and irritable mind.

      From the electronic tube to the field effect tube at the beginning of the 20th century, the sound technology has become increasingly mature and the fidelity has been increasingly improved. With the advent of the era of intelligent technology and the Internet of Things, the field of intelligent audio is "a hundred flowers bloom and a hundred schools of thought contend". O2 Cloud Audio is also a dark horse. Let me bring it to you O2 Cloud Audio Evaluation of.

"Hello, schoolmate, your express package has arrived, please sign in the XX area of the XX express online store." The long-awaited O2 Cloud Audio has ended its long logistics journey, and is coming to my bowl soon. Unable to stop the joy in my heart, I put down my work and took Xiao O home.

Packaging

        When I saw Xiao O for the first time, I was surprised that his package was so "huge", and I still fell down when I picked him up. I guess Xiao O is a "little fat paper"! When I opened the outermost paper packaging, the inner packaging and buffer cotton came into sight, and the double insurance can always make people feel more secure.

          After taking out the inner packing box carefully, the inner packing gave me the feeling of simplicity with dignity. The outline of the hexahedron and the white color make people feel clean and flawless. There are few words on the front of the package, such as "O2 cloud sound, personalized recommendation, voice song ordering, gesture control". The picture and logo are clear, simple and clear.

          The simplicity on the four sides of the inner packaging ring is still the same, and the front side only uses the words "ring you want to hear", which just shows the focus in front of the user and represents a level of intelligent audio. The extension belt can facilitate the user to open the box. Gray logo is printed on both sides, and one of them is a QR code printed with official website and WeChat official account. The rear side mentioned the product features, packaging content, product color and basic parameters, so that users can more specifically understand O2 Cloud Audio.

After opening the APP, the mobile phone and the small O need to be in the same WIFI access point to achieve the control function.

Click the setting interface to bind to the mainstream music platform account. Currently, only 4 Platforms , respectively Douban FM, Netease Cloud Music, QQ Music, Xiami Music Personally, I think this is enough. In addition set alarm And other settings, plus the reminder function, which is more considerate.

After adding an account, you can see the song information in the music account, listen to your favorite music, recommended music, and leaderboard, Fully functional and more convenient to find the type of music you want to listen to 。

The account will also be displayed in the menu bar.

[Usage]

        I have been with Xiao O for several days, and I am familiar with him. In terms of sound quality and sound effect, Xiao O's performance is not bad. He is small, but his low frequency is strong, and his sinking is in place; Medium and high frequency are relatively weak. In this way, Xiao O is more suitable for playing rock music.

        After using the O2 Cloud Audio for a period of time, the heating is obvious, especially in the touch screen area, which will feel hot when touching.

The battery life is good. I have never tried to run out of battery (PS: children with obsessive-compulsive disorder can't afford to be hurt). It can approach the theoretical playback time of 8 hours and standby time of 25 hours.

Conclusion: O2 Cloud Audio is a smart cloud audio with convenient use and good sound quality. No matter at home or traveling, we can let Xiao O accompany us and let music fill our lives.
