In fact, when I first got it, I was shocked by the huge size of the product. Generally speaking, similar speakers are not very large, and small packages can be light and portable. However, O2 gave me a big surprise. Seeing this package, I knew that the sound quality of O2 was definitely not comparable to those of the previous Bluetooth speakers. O2 really proved its value during the audition, The bass effect is shocking, and the middle and high tones are layered and transparent, and the functions are very novel. I can't put it down because of gesture manipulation, voice demand, and massive cloud resources. It's rare to experience such a wonderful product. Let's feel O2 cloud sound together.

The huge package doomed to the noble quality of O2. The white cardboard box has a very good texture. The main color is white O2. The model I got is black and classic red, which is said to be very amazing.

Square packaging, round products, everything implies the philosophy of a round sky and a place, which is very harmonious.

From any point of view, O2 packaging is a perfect presentation.

The packaging box is opened by lifting, and "ring you want to hear" is the most true embodiment of O2.

After opening the package, the black O2 shocked me again. Although it was dark, it had a charming eye that could see through people's hearts.

The packaging can protect the product very well. The instructions for O2 are very simple, and the origami instructions are very detailed. In fact, the operation is very simple and gives a very good experience.

O2 is still very heavy. It sounds pure and transparent in the treble, rich and solid in the bass, balanced and full in the midrange. It reproduces the perfect true sound, and feels like it reaches the heart of the people. It benefits from the HiFi level independent decoding chip and Class D digital power amplifier used in O2; Three loudspeakers, low frequency phase inversion tube design. When I played it at home, I felt that the whole living room was full of music rhythm, which shocked people.

The three speakers of O2 are hidden under the mask. If we look straight at it, there is only a round LCD screen. In fact, don't underestimate it. Although it is not big, it is touch controlled. We will introduce it later.

O2 has a built-in 32.6Wh lithium battery, which can play for 8 hours continuously on a single charge, and can meet the daily needs of going out.

O2 is very portable. There is a handle behind it, which can be carried for short distance walking.

The arc groove is just buckled by the hand, which is very convenient.

From the side, O2 is not a sugar bean type, but rather inclined.

The bottom is made of very bright plastic material, which looks very good.

In fact, from the side, it seems that there is a feeling of Japanese bun popular in the fashion industry.

In the startup scenario of O2, the circular touch screen can display various states.

The brightness of the touch screen is very good, and it is also clearly visible outdoors.

In fact, the O2 operating system is very simple, and we will introduce it in detail later.

Information on the bottom of the audio, detailed product description, and manufacturer information.

Below the handle are the power on key and charging interface. Long press the power on key to power on, and soft power off from the screen can be used to shut down.

The O2 charger is also very textured.

I like O2's Charming Eye very much. I really love it.

The shape of cobblestone is simple but not simple, which is very in line with the current trend.

Next, let's look at the operation of O2. In fact, as long as the host is connected to the Internet, it can play cloud songs all the time without APP. This function is very novel.

After power on, the O2 Cloud Audio screen appears. The first thing to set is wireless connection.

Scan your own WIFI, and then click in to enter the password connection, and it is OK.

Automatically start playing cloud songs, which is too smart.

Cover screenshots of different songs. Next, we will introduce O2's most praiseworthy voice on demand and gesture control.

Because the product picture is not obvious, let's look at the official introduction picture. The bottom point is the location of voice interaction. After a light click, the picture of "Please speak" will appear. Voice on demand can be played, and the recognition rate is very high. This is very commendable. If I can't recognize it, it will display words I don't understand, and then continue to play the song being played. The top point is the position where the playback is paused. A light click can pause the playback. The left and right points are volume control points. Pressing and holding the left side will reduce the volume, and the right side will increase the volume. Besides, gesture operation is supported. It's fun to use your hand to swing from left to right to increase the volume, and vice versa.

When O2 plays music, you can directly say "Hello Little O", and this interface will appear. Say the name of the song or singer, and O2 will automatically search for the song.

Slide the playback interface up and down to switch songs, and touch screen operation can support many convenient operation methods.

After the O2 mobile app is opened, there is a scene radio station. Various scenes are suitable for a variety of atmospheres, but unfortunately, we can't see what songs are in the scene. We can only play them randomly.

The APP version of O2 configures music services and expands more music resources.

Although Douban and NetEase Cloud Music do not support song search, the author came up with a way to collect my favorite songs in NetEase My Music. In NetEase Cloud Music, click My Music to see the list of my favorite songs, which is a good tip.

Finally, to sum up, O2 has brought us different feelings in terms of both sound quality and operating experience. The unique HIFI level independent decoding chip, D-level digital power amplifier, three speakers, and low-frequency phase inversion tube design have achieved the effect of pure and transparent treble, rich and solid bass, and balanced and full midrange. It has been a relatively high-end positioning in household portable audio. The advanced voice on demand function and smooth gesture control function make O2 even more advanced. Wirelessly connected Massive music resources can also bring unlimited enjoyment to users, which is generally very good. However, there are still several suggestions to mention. O2 does not have USB/TF or AUX Socket, which will lose a considerable part of the functions. Without the network, O2 can only be used as an art piece. It is recommended that the manufacturer configure it as standard USB /TF And AUX to add more usage scenarios. Gesture manipulation has been very mature in the process of use, but voice on demand is still a bit urgent. Sometimes it can't be recognized after several times of speaking, which is very bad. The voice recognition function needs further improvement. However, these shortcomings do not hide the merits. As for cloud audio, O2 has already performed very well. There are a lot of cloud music, which shocks the audio. If I give O2 a full score of 10 points, I will give O2 a high score of 9 points, which is really worth having.
