Introduction

With the continuous development of science and technology, sound, as a sound playing tool, is widely used in people's life and work; In the living room, park square, office or some leisure places at home, you can see all kinds of sound systems. People use them to listen to music and radio to cultivate their feelings and relax. Throughout the market, most audio products are still in the stage of single function and limited use environment; Xiao Bian believes that only with such factors as excellent sound quality, beautiful appearance, powerful and practical functions can they be competitive in the market of similar products and be favored by consumers.

Today, the O2 Cloud Audio is a high-quality wireless Internet product designed for young people. It combines gesture control, voice on demand, and personalized music recommendation in the most reasonable way to present a music feast to users with the most beautiful sound quality effect; The appearance of the product also breaks away from the long and square structure of the traditional sound. It adopts the pebble shape, which has a good visual effect. A variety of color styles also enable the product to integrate into various forms of home environment. Is the practical effect of this stereo the same as that introduced by the editor? Next, let's go into this evaluation trip together with our editor.

Open box display

O2 Cloud Audio is packaged in a rectangular cardboard gift box. The box surface is the appearance pattern of O2 Cloud Audio, which is round and cute. The size of this product is really large, and I was surprised when I received the express delivery.

Orange silk cloth is used as the handle at the junction of the packaging box, Compared with the upper and lower button box, the package is easier to open. The design concept is convenient for users, and the details of the product are in place. The theme of "ring you want to hear" highlights the fundamental concept of this product, which is to allow users to enjoy the joy of music at will.

On the other side of the package, the characteristics of O2 Cloud Audio are described in detail: scene radio, intelligent push, no download of cloud content, gesture control, voice control, independent decoding, surround sound, round touch screen, etc. The appearance design, sound quality effect and control mode are all worth looking forward to.

Can't wait to open the packaging box to see this O2 cloud audio. In order to better set off the appearance and artistic sense of the surface fabric of the audio, it is covered with a layer of opaque white plastic plate, which makes it easier for users to focus their vision on the audio body, highlighting its beautiful appearance.

The stereo is like a huge pebble embedded in a hard black plastic mold. The product is firmly fixed inside, and there is no large gap around, effectively preventing the product from being damaged by collision during transportation.

In addition to the audio body, the product also has a special power adapter and a user manual; On the whole, the parts are in good order. There is nothing special about them. However, the style of the instruction manual is relatively novel and unique. The circular card mode and the shape and structure of the speaker echo each other, adding a sense of beauty.

The user manual gives a detailed description of the audio function keys, operation methods, precautions, and relevant parameters and performance. The editor recommends that you read carefully before use. After all, this O2 Cloud Audio has many functions that we are not familiar with, Read carefully to avoid misoperation during use.

For the front and side display of the audio system, in order to help people better understand this product, the editor summarizes the main parameters as follows:

O2 The upper part of the cloud audio body is covered with suede cloth and the piano paint baking process of the bright side below. In combination with the pebble structure and slope design, the appearance looks beautiful, fresh, delicate and full of science and technology. Small audio quality HiFi Class I independent decoding chip, Class D digital power amplifier, low-frequency phase inversion tube design, both low and high tones have a good effect, restoring the sound to its original state.

Detail display

O2 One of the highlights of Cloud Audio that distinguishes it from other similar products is that it has a 1.9-inch touch color screen. Users no longer need to touch complex physical keys to control the audio. Through this screen, you can achieve system settings, music background mode selection, song information display and many other functions; Although the resolution is not too high and the touch sensitivity is not too bad, because the touch screen area is small, it will be a little difficult to input a small area such as WiFi password. The editor suggested that the size of the screen be expanded to make it more convenient to use.

The back of the audio is the DC power interface and the position of the switch button. Although the product buttons are simple, the editor thinks that several common functions should be added, such as Aux in audio input interface and USB interface. At present, O2 Cloud Audio cannot be wired with computer tablet products as an external audio device, which has some limitations on use; The USB interface function can facilitate the user to play the music in the storage device without WiFi network.

The bottom of the stereo briefly introduces the model, speaker, output specifications and parameters. There are four long anti-skid rubber pads around. In addition to the weight of the stereo itself, it can be stably placed in any desktop, tea table, bedside table and other environments. There is no need to worry about sliding and toppling.

O2 The box of Yunsheng is made of ABS engineering clinker, and the surface is covered with piano paint baking process. The top surface is covered with high-grade flannelette fabric, High density air holes ensure sound penetration without damage, and the surface feels It feels very good. Overall, it looks bright, simple and elegant. However, Xiaobian thinks that the paint baking process at the bottom is easy to stick fingerprints and impurities, and is not resistant to dirt.

There is a relatively hidden LED status indicator at the bottom of the audio screen. The light color has multiple modes. The indicator light will change when the machine is turned on and off and each time the touch control speaker is operated. Users can intuitively understand the operating status of the audio according to the color and flicker. Xiaobian suggested that it would be better to leave the LED outside. It seems a bit unnatural to be wrapped in the flannelette on the surface.

You can see that the contact connection between the flannelette on the top of the stereo and the body shell below is also highly closed, and there is no gap.

The connector part of the power adapter is somewhat different from the 12V power supply we usually contact. The 18V power adapter used by O2 Cloud Audio has caused the disadvantage that similar electronic products cannot be used universally.

Use display

The use method of O2 cloud audio is also relatively simple. O2 cloud audio has built-in O2 system System, When using it for the first time, you can play music after connecting to the WiFi network at home through the round touch screen.

Press and hold the power button for 5 seconds to start the machine, and the screen will light up the O2 cloud sound and the Slogan that can hear the good sound for one second, accompanied by the crisp and graceful startup music. After being connected to the network, the small O can also display the temperature, weather conditions and time information of the region on the standby play interface.

As a powerful audio, the use of the small O also requires the cooperation of smart phones to realize its value. The introduction of the connection with mobile phones and software APP will be detailed in the following chapter. Here, the editor will first reveal that the software is also very powerful.

O2 The core highlight of the audio system is its gesture operation part. Instead of the traditional key control, the audio playback function can be operated through touch and gesture. By changing the advanced settings in the options and turning on the gesture song changing function, you can switch songs by sliding your palm left and right on the sound surface, which is full of technological elements.

In addition to the gesture cut song, there are corresponding tactile areas at the top, bottom, left and right of the audio screen. The editor summarizes the specific functions as follows:

Single touch on the top of the touch screen: pause/play function

Double tap the upper end of the touch screen: realize the function of collecting songs

Tap the left side of the touch screen to reduce the volume

Tap the right side of the touch screen to increase the volume

Tap the bottom of the touch screen: to realize the voice command function, read the voice command through the microphone to intelligently identify and search the corresponding song name.

For the voice control function, in addition to tapping the bottom of the audio system, you can also directly say "Hello, Little O" to wake up the voice play function; The editor thinks that Xiao O's voice is relatively simple and can only order songs. It lacks some intelligent voice interaction functions, such as asking about the weather, broadcasting time, schedule reminder, leisure dialogue, etc. If these elements are added, I believe that user satisfaction will also increase.

The left and right swipes of the touch screen can respectively enter the setting interface, including software update WiFi settings, power off, system information, etc. Swipe to the right to enter the scene radio page, which successively includes: electronic music, sports, cloudy, my collection, intelligent recommendation, party, party, romance, dinner, journey, etc. You can choose your own scene according to your preference, and the system will automatically play the corresponding music according to the selected scene.

It should be noted that the gesture operation of small O needs to keep the body in a horizontal state, otherwise it cannot be achieved. This design is very humanized, which avoids accidental touch when moving the audio.

Introduction to APP

The above QR code is used to download and install the O2Player software APP. After successful installation, you can see that the interface is very simple, including four function option menus: scene radio, Netease Cloud Music, music service configuration, and settings.

In the setting of scene radio, O2 Cloud Audio has 12 built-in scenes, and each scene mode contains a large number of songs with different music styles. Whether it is work study or leisure relaxation, you can always find a music environment suitable for your mood; It's a pity that there is no synchronized display of lyrics on the display interface of the song player. I hope it can be developed later.

In the Netease Cloud Music interface, you can see my music, popular song lists, leaderboard music view, personalized recommendation and other music search lists, and you can find the corresponding music according to your favorite. But why are the catalogues in English? Wouldn't it be better to change them to Chinese?

In the configuration of music service, you can also add Douban FM personalized music listening tool to listen to the music you want; In the setting interface, you can view the connection status of the small O, software update and other related operations. In general, some functions of Xiaoo's APP software are too simple, and its attraction to players needs to be improved. We hope to integrate more and more interesting functional projects.

summary

About this evaluation post of O2 Cloud Audio, the editor has brought so many things to you. There may be some things in the article that are not detailed or comprehensive. Please comment and correct more. In general, O2 Cloud Audio has killed many similar products in the market due to its beautiful appearance and excellent sound quality; However, during the evaluation process, Xiaobian also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of Xiaobian.

1、 The touch screen size of the audio system is a little small, and it can't be touched occasionally when inputting letters or touching. It is recommended to expand the screen size to facilitate user use.

2、 The speaker itself lacks the AUX IN interface and cannot be used as an external audio device to connect computers and tablet products, which greatly reduces the use environment. It is recommended that this part of functions be added later.

3、 The USB interface is added to enable Xiao O to play audio files through storage devices even when he is not connected to the network.

4、 The voice control function of the audio system is too simple, lacking some intelligent voice functions. I hope some intelligent voice interaction elements can be added.

5、 It is recommended that all LED status indicators on the audio surface leak out. The effect of covering them with flannelette is not ideal.

6、 It is suggested to enrich the content of software APP to make Dongdong more interesting.

7. Add the storage function of the body itself, so that users can download favorite music files, store them in it, and listen to them at any time.
