preface:

In recent years, more and more traditional hardware has joined the ranks of intelligence and started to rely on cloud services to make themselves more distinctive and outstanding. In terms of cloud audio, the author has been exposed to many smart speakers relying on cloud services a year ago. Up to now, there are still few products that the author likes. These smart speakers can often play all kinds of cloud music, voice songs, voice chat, and even voice control household appliances. After having many functions, They seem to forget that they are the essence of sound. The author always thinks that an intelligent cloud speaker is like an old traditional wooden bucket, and the sound quality is the shortest wood. All intelligent functions can make the bucket even better, but it can't hold more water. Therefore, no matter how intelligent and humanized the speakers are, they are actually used for listening. Listening must have good sound!
When I saw O2 Cloud Audio on all major websites, even when the crowdfunding exceeded 200W, I still refused, because I experienced too many smart speakers without sound quality, and I never believed it anymore. Later, I heard from many friends that this is one of the few smart speakers that pays attention to sound quality in recent years, so I finally got excited. Now I am lucky to experience this model in 72 How about the experience of O2 Cloud Audio? Let me bring some of my own experience.


Unpacking:

▼ Get it for the first time When using O2 Cloud Audio, it is much larger than expected, and the packaging box is slanted to open, so the material is very solid!

▼ A pull rope is designed at the opening of the box to facilitate the opening of the box, and the words "ring you want to hear" are printed, ready to open the box.

▼ Open the package directly, black The O2 cloud sound is directly visible, The O2 Cloud Audio actually has five colors: black, white, red, yellow and blue. This time, I received the black version, which is very impressive.
▼ The following is a family photo, including O2 cloud audio, operating instructions and charging power supply.



Details:

▼ This paragraph O2 Cloud Audio adopts the overall black design, and the whole machine adopts the oblique circle design with a diameter of 25cm. Above the entire round audio, except for a 1.9 inch 320 * 320 circular capacitive touch screen, it is covered by black mesh. Under the black mesh, 2.1 sound source design is actually used.
▼ The bottom of the O2 Cloud Audio is designed with a black rubber pad, which can effectively reduce the resonance problem of the audio contact surface. The rest of the bottom area is made of mirror plastic material. It is worth mentioning that although the mirror is beautiful, it is a collector of various fingerprints and dust. It is not beautiful after spending. Fortunately, the design of the mirror area is at the bottom of the entire audio, and cannot be detected in actual use. The switch and power interface of audio are also designed at the bottom and upper position.
▼ There is another design that the author has never imagined. The back of the stereo is also designed with such a handle. After careful study, the author found that the hole can directly lead to the interior of the stereo to the left. At this time, it was discovered that the hole was originally The O2 cloud audio has its own inversion hole, so the portable cloud audio will also have its own inversion hole, so we are more expecting its sound quality.

▼ It is not only an inverted hole, but also a portable port, which is unexpected.
▼ At the end of the detailed introduction, there is another thing worth complaining about, When the audio is placed on the plane, the power key of O2 Cloud Audio is basically designed at the bottom of the oval shape. It is not easy to turn on the audio when it is placed properly. It is suggested that the key should be set at the bottom in front of the audio for easier operation.



user's experience:

▼ Click the switch at the bottom of the audio to turn O2 Cloud Audio is turned on.
▼ The first time you start the machine, it will show on the 1.9 "round screen Operating tips of O2 Cloud Audio.
Slide the screen up and down to switch songs, and slide the screen left and right to access more functional operations.
In addition to operating on the screen O2 cloud audio can also control music by touching different positions of the round black mesh cloth at the same time. When touching the upper part of the screen, you can play/pause. When touching the left side of the screen, you can reduce the volume. When touching the right side of the screen, you can increase the volume. When touching the lower part of the screen, you can quickly access the voice interaction function.
When the display is finished After the operation prompt of O2 Cloud Audio, the QR code download prompt of the mobile app will be displayed.
▼ This indicates that as Cloud audio still needs to be controlled by the mobile phone APP, which can be scanned, downloaded and installed directly with the mobile phone camera.
▼ After downloading and installing the app on the mobile phone, you need to set the network in the audio. In the network setting, The screen of O2 Cloud Audio provides full keyboard virtual input. You can directly enter the password to connect to the network.
▼ After the network connection is successful, O2 Cloud Audio will automatically start playing music. Randomly tried to switch songs up and down, very sensitive.

▼ Swipe the screen to the right to enter Various settings of O2 cloud sound.
▼ In the settings, you can set WIFI settings, power off and restart, timed power off and other functions. At the same time, you can set two different screen saver interfaces according to user preferences, one is the weather clock interface, One is the cool spectrum interface, which can be closed if you don't like it. meanwhile O2 Cloud Audio only supports gesture song cutting, automatic brightness adjustment, voice wake-up, DLNA and other functions.
▼ Swipe the interface to the left in the play interface to enter the selection interface of various styles of music channels, and the recommendations of these styles are also O2 Cloud Audio is a highly praised listening method, because this is the essence of cloud music. It sounds like you want to listen 。
▼ When we open the mobile app, we still see various music channel recommendations in the main interface of the app. While the song is playing, The display interface of O2 Cloud Audio will see a rotating vinyl disc, while in the center of the disc is an album picture of music playing, and an orange circle outside the vinyl disc will display the time axis of playing music.
▼ In addition to playing music channels of various styles, it also supports the sound source playing of Douban Music and Netease Cloud Music, so that O2 Cloud Sound has more sound sources.
▼ The author has tried to add the music service of NetEase Cloud Music, so that he can play the music in various NetEase Cloud music libraries directly in the app of O2 Cloud Audio. What is worth mentioning here is that although O2 Cloud Audio supports the playing of douban music and Netease Cloud Music resources, but as a cloud audio, there is still much room for improvement in the expansion of playing resources. It is suggested to add Himalayan and other cloud resources here.
▼ There are not many built-in resources for O2 cloud music, Fortunately, in order to make O2 Cloud Audio plays more music, and the recent upgrade finally makes O2 cloud audio has DLNA function. With this function, you can directly use various music apps to O2 Cloud Audio Music has been pushed. The author tried the Xiami music that he often used, and directly connected DLNA in the music playing interface.
▼ With DLNA connection playing, The display interface of O2 Cloud Audio will also display DLNA, and will not display the rotating vinyl discs and music information. After all, under the playing settings of DLNA, our attention is still on the phone, The screen display of O2 cloud audio is irrelevant.
▼ In addition to these playing methods, O2 Cloud Audio also supports voice interaction In the screen prompt of O2 Cloud Audio, you can click the lower part of the screen to activate the voice recognition interaction function. You can play all kinds of music through voice, such as "play a Nanshannan" or "play Eason Chan's song". If you are setting the management When the voice wake-up function is enabled, you only need to O2 Cloud Audio Say "Hello, little O!" to activate Voice recognition interaction function of O2 Cloud Audio, and then voice song request. What needs to be said here is that when you say and play Eason Chan's song, you can accurately identify it, but after identifying it, it is found that the built-in O2 cloud audio only knows the only song of Eason Chan's "Spend Long Years with You", but if you play other Eason Chan's song names interactively with voice, you can actually identify and play them, But these songs are not divided into the voice interaction of Eason Chan's songs. In addition, occasionally voice can not wake up. There should be some bugs. Hope to optimize.
▼ Finally offer Operation video of O2 Cloud Audio, including voice interaction.

About sound quality:

Thanks to the HiFi level independent decoding chip and the 2.1 combination of a 2-inch 4-ohm 5W full frequency unit and a 3.5-inch 8-ohm 15W bass unit, you can basically not worry about the sound quality of the O2 cloud audio. All the portable speakers I have ever worked with have basically adopted the combination of full frequency units and a passive radiator. This design often allows smaller speaker units, making the bass and midrange responses more accurate and better separation. However, such speakers also have a disadvantage, that is, as the bass continues to sink, In the end, it will become more and more powerless. After all, it cannot produce a stronger bass, so this design is often only suitable for very small portable speakers. For the O2 speaker, which is made of solid materials, two full frequency units are directly used for the performance of mid-range and treble. An independent high-power bass unit with inverted holes is designed for the performance of bass, bringing a very durable mid-range and treble sound and a more mellow bass to O2 Cloud Sound. When the volume is adjusted to 70%, it is too high to hold the square dance, and the bass is still strong and solid. It is hard to imagine that such a small cloud sound will also have such a rich and sufficient bass. O2 Cloud Sound is still a speaker that focuses on mid bass. With the support of a high-power bass unit, the voice of O2 Cloud Sound, whether male or female, will be more durable. The author randomly played Eason Chan's songs, one of which could not be stopped. Under such a magnetic sound, he was totally unable to extricate himself. The author believed that the most suitable for listening to O2 cloud speakers was Eason Chan, and he was not happy to hear it. In terms of treble, it is not as pleasant as the mid bass. The author played Zhang Liangying's "Painting Heart". Zhang Liangying's treble singing still has some extension, but it is still lacking and not transparent. Especially in the dolphin part of the song, there is no natural penetration. Maybe there is also the problem of cloud music resources. After all, all cloud music cannot be guaranteed to be of high quality, so it can only be used as a reference. in general, O2 Cloud Sound is a sound box more suitable for mid bass music. Those who like mid bass music can't miss it. The full midrange and mellow bass are absolutely your favorite.


About endurance:

O2 Cloud Audio built-in 8800mA lithium battery, which takes about 3 hours to fully charge. When the power is full and the volume is at 40%, the author tries to play non-stop until it automatically shuts down. It takes about five hours and a few minutes. It is basically enough for a large cloud audio that must rely on the network. Here I still have something to complain about, Although the O2 Cloud Audio has a built-in 4G memory, it cannot be used off the network. Although it is targeted at the cloud audio, since it is designed to be portable and has a built-in battery, it is inevitable to carry it out without the network. It cannot play music off the network. This is unscientific. Maybe this function will be realized by upgrading the firmware in the future. Look forward to it.


Conclusion:
O2 Cloud Sound is a rare smart speaker that pays attention to good sound quality in recent years. The design of 2.1 sound source and inversion hole is the guarantee of sound quality. In terms of operation, there is always a way for you. It not only supports ordinary touch screen operation, physical touch operation, mobile app operation, but also supports gesture operation and voice interactive operation. More operation modes make you more convenient to use at any time O2 Cloud Audio. In terms of resources, in addition to the music of the built-in application scenario, it also adds resources such as Douban Music and Netease Cloud Music. At the same time, it also supports DLNA connection, which can completely keep your music going. Finally hope O2 Cloud audio can be continuously optimized and better done, so that more people can enjoy the fun of cloud music.
