In modern life, music has become an indispensable part of life and entertainment. You used to hold it MP3 、 Ipod Listen to music. Now you can listen to popular songs with a small portable stereo on your mobile phone, but these often can't meet your needs for music quality. A good stereo needs you to slowly select and listen to it. Before playing music on the walkman, you had to bring headphones to listen. Now a small stereo frees your ears. The walkman only has to listen to songs repeatedly, A tape turns over and over; MP3 The storage space is limited, and you will get tired of listening for a long time. If you want to listen to other fresh songs, you should also consider the storage space. Today, with advanced technology, is there a device that allows you to listen to the latest songs without having to listen to them, regardless of local storage space? Of course, the answer is that today's protagonist—— O2 Cloud audio.

“ O2 ”When I saw the name, the first thing I thought of was the chemical symbol of oxygen. It's not hard to imagine that when you are depressed and lonely and need someone to accompany you when you need a sense of freshness, then a stereo might be able to replace it, bringing you oxygen and freshness. First of all, I would like to thank Lei Feng.com for giving me the opportunity to try it out, giving me the opportunity to breathe the oxygen brought by music.

▼ Summarize recommendations

For a cloud audio, the price of this O2 899 is not cheap. If you want to buy an audio with good sound quality, convenient operation, high practicality and easy portability, then O2 is definitely a good choice. The sound quality of the audio is not inferior to that of the home audio on the market, HIFI audio quality can meet your needs for music audio quality. If you listen to music at home, the built-in battery has a life of about 8 hours, which is completely enough to listen to songs when you go out (self driving tours, places without sockets). Of course, this audio system also has other shortcomings that need to be improved——

The following are the areas I hope to improve during use:

1. When switching songs up and down, they play slowly and get stuck;

2. When there is noise around or music is playing, the failure rate is high when small O is awakened to play voice;

3. The circular LCD is slightly loose from the body;

4. Suggested increase plus A UX Audio input, which can also be played when connected to the computer;

5. TF card playing, playing local music when there is no network, or downloading cloud music to local;

6. If there is no power when using the built-in power supply, you want to give voice prompts;

7. The success rate of speech recognition of English songs is low;

8. Add service content to mobile APP, such as news broadcast;

9. The timing function can add notes to remind you what to do at what time.

Finally, I would like to thank Lei Feng.com for giving me the opportunity to try it, so that I can experience the relaxation that this O2 smart cloud audio brings to my mood and enjoy the joy that music brings!
