How to evaluate a smart speaker? In my experience, it may be slightly different from the evaluation of lossless playback equipment. The terminal can reduce the loss through the wire of the headset, so the sound quality is relatively high. And sound is transmitted through sound, so air will inevitably lead to the loss of sound quality. The same terminal does not need the same loud sound as the audio. Some terminals also need some earphones to increase the thrust, so there is some error when testing the audio according to the standard of nondestructive player. Now let's evaluate the O2 cloud speakers according to some of my standards.

1、 Beautiful appearance

The overall shape of O2 is cobblestone. The mirror plastic with integrated injection molding is added below, and the upper part is red dust-proof mesh. The first sound hole is on the top, and the color of the dust-proof cloth is perfectly integrated with the bottom of the mirror. The concave prototype screen is used in the middle of the screen, and the bright metal ring with polishing treatment is used around the screen, which is very harmonious with the red background.

There are gesture sensors around the touch screen, which can realize gesture operation, reduce the dependence on touch screen, and make it more scientific and futuristic. The bottom is equipped with a rubber coated anti slip mat design, which has great damping and strong anti slip performance.

The sound looks like pebbles. The surface is covered with a black mesh cover. A 1.9 inch circular capacitive screen is inlaid at the bottom of the middle. The silver frame on the side is transitional. It looks very metallic in the sun. There is no button on the front of the body.

Contrary to the front mesh cover, the piano paint process on the back is brilliant, but there is a disadvantage that it is easy to produce scratches and fingerprints.

There is a large anti-skid pad at the bottom of the fuselage, which can play a anti-skid effect. There is simple parameter information on the anti-skid pad. There is a black portable slot on the back of the body, which can be easily lifted by one hand. The power interface and power key are arranged below the portable slot.

The whole body has no buttons except the power button, but we can operate the audio, gesture, screen, voice and app in many ways.

In the smart era, mobile phones are becoming more and more bloated, because as long as a traditional smart device is equipped with an app, the manufacturer will call it a smart device. On the contrary, I think it is smart to remove the app and then operate independently online. O2 can completely operate independently without the app, which I like very much.

Gesture operation can greatly facilitate us. When you scan over the sound with your hand from left to right, you can switch to the next song. When you scan over the sound with your hand from right to left, you can switch to the next song. When you hover over the sound, the distance between your hand and the sound should not exceed 5 cm. When you place your hand on the left side of the sound box surface screen, the volume will automatically decrease. When you place your hand on the right side of the screen, the volume will increase. When you place your hand on the top of the sound box surface, you can play/pause, Putting your hand under the screen will trigger XiaoO's voice operation function. There is a built-in indicator light at the bottom of the screen. After a few days of use, XiaoO's gesture operation is still very sensitive, which completely subverts the traditional operation mode. Of course, if you are not accustomed to gesture switching songs, we can also turn off gesture switching songs. The voice recognition function supports voice song request and weather broadcast. The weather can also be displayed when the screen is in standby.

As one of the three highlights of Little O, the voice call function is very desirable. We can call "Hello Little O" when we are on standby and then start the voice assistant. However, after using it, we find that the voice recognition function is not satisfactory. In particular, the voice recognition rate is generally only able to recognize some simple song names, and the recognition rate needs to be improved. Small O supports a variety of built-in scene modes for scene radio broadcast.

Xiao O has its own independent operating system. After the firmware is upgraded, it can support DLNA playback. As long as the mobile phone and Xiao O are under the same wifi, the music on the mobile phone can be played in real time on Xiao O through the player that supports DLNA. Apple's Airplay is still in the beta phase, and the next version will be released.

At present, the App only supports IOS version, and the Android version is still in the internal testing stage, but at this stage, the mobile phone can only control the audio through the app when it is connected to the same wifi with the small O, There are three menus in the app: scene radio, music service configuration and settings. Scene radio is also a variety of radio stations built in Xiaoo. The configuration of music service can bind four streaming media, namely douban, Netease Cloud Music, QQ Music and Xiami Music, through the account, which can satisfy most people's preferences.

The alarm clock can be set in the settings, so we just need to set the time and music, and then give the morning wake-up service to Xiao O. Of course, it also supports the regular stop of broadcasting, playing light music at night, and then relaxing, slowly entering the sleep state, and no longer having to worry about the music playing when people are asleep.

Small O is a speaker product based on WIFI wireless system, with a built-in 8800mAh battery. It can play music for up to 8 hours when fully charged, and its memory is 4G. It can collect hundreds of songs. However, the currently collected songs cannot be played when the audio is not connected to wifi. The bass is very strong, the alto is full, and the treble is transparent and natural, which can please most people's ears.

Advantages: Small O supports online streaming music, convenient gesture operation, voice control and weather broadcast

Disadvantages: Bluetooth connection is not supported, and there is no audio interface. App control can only be performed under the same wifi. Voice recognition needs to be improved. Currently, favorite songs do not support offline playback.
