The Anthem of Autumn

——- A beautiful hymn in this autumn season

Write before the opening:

Once I saw the concept map of O2 on foreign websites, I was directly fascinated by the design of O2. The design of O2 is streamlined as a whole, and it is composed of upper and lower parts. The lower part is an integrated injection molded shell, and the bottom is equipped with a rubber coated anti-skid pad. The top is oval, the tail is streamlined, and the surface is covered with dust-proof flannelette.

The overall workmanship is very exquisite, and there are lots of small designs, such as the physical key at the end of the product and the handle of the product showing a funny smile. It is also worth affirming that the engineers put the bass phase inversion hole into the product handle to avoid adding too many abrupt places on the complete surface.

1、 Product design - free breathing of air and oxygen

Most of the speakers I have seen are square or triangular. Creativity is basically here, and aesthetics is tired. The pebble shaped design is the most special speaker design I have ever seen. As O2 advocates freedom like oxygen, lightness in design brings us a freer visual experience, which brings us different impacts at the beginning.

  The upper half of O2 is covered with a dust-proof cloth, which can effectively prevent the impact of dust on the sound outlet, but the non removable and upward plane will inevitably lead to the accumulation of dust, which is easy to get dirty after a long time. It is hoped that replaceable mesh can be added in the future, and the launch of corresponding wall hanging and other accessories can be accelerated.

It can be seen that O2 is designed with great care everywhere. The back of the product is designed with a non slip rubber pad, and the official learned that this dust pad was urgently upgraded before the distribution of crowdfunding products, adding damping, so that the speakers can be better placed on a smooth surface. The handle on the back has a built-in low-frequency guide hole, which increases the sound quality and avoids the damage to the overall appearance design.

The front display screen is equipped with a metal aperture around it, so that the screen and the front panel are softly integrated. Because the color of the screen is very deep, it is very suitable for the black shape. Of course, other color matching is also a good choice. The color of flannelette with different color matching is slightly different from that of the lower shell.

2、 Sound quality: interpretation of music freedom

Starting from the sound channel, 2.1 means that the speaker is divided into two frequency dividers. The small speaker is mainly high-frequency, the subwoofer is mainly bass, and the bass is a separate speaker with a large diameter. This popular point means that the bass dive is very deep, but the midrange is relatively weak. Personally, I think it might be better to use 2.0 channels. Maybe most people think that a good bass is a good speaker, but this is not the case in years of hifi experience. For music, 2.0 may be better, but for movies DJ、 Game 2.1 is more shocking. Radish and vegetables have their own preferences, so don't comment too much.

The frequency response range is wide enough. The range that ordinary human ears can hear is 20Hz~20KHz. The frequency response of high-quality power amplifiers should be about+/-0.1dB from 20Hz to 20KHz. There is nothing to say about this. Now let's talk about the power amplifier. O2 uses Class D power amplifier, which is usually used in cars, so the volume and effect are very guaranteed and suitable for listening to popular music. What I value more is the 10 segment EQ regulation. Although this function has not been seen in the current product, the official said that this function will be added later, which should give O2 more free music interpretation. On the importance of EQ regulation, you can tell us more about it. How to regulate it is based on your personal preferences. You can refer to the Golden Law of EQ

Now let's talk about my sound quality after this week's experience. I have evaluated songs like Paradise, Ambush, I think you are going, Cai Qin's Ferry and Hotel California. Let's talk about the bass emphasized by the product first. Although the bass guide hole is added, the bass is not as amazing as I thought. I think it is a debugging problem, and the bass is not well displayed, perhaps because the product is an engineering machine.

What about IF? It's completely opposite to the weakness of 2.1 channel I analyzed earlier. The performance of IF is better than that of low frequency. I don't know how to explain this situation. From Tengger's paradise, it can be heard that the restoration of human voice is very clear, and can restore the trembling at the end of the voice. The expressive force is very good. The penetration of high frequency is fairly good, and you can feel the crisp sound of musical instruments and life. In general, the tri band design of O2 has a large preference, and the later tuning still needs to be updated. I hope that the later tuning can play a strong bass effect.

3、 Control part - free play O2

     O2 You can freely play with O2 through touch, gesture, touch screen, voice and app control. What I want to say is that O2 can really adapt to a variety of scenarios in my experience. You can freely control it in the kitchen and living room. Gesture song cutting and voice can complete song searching, song cutting and other operations when your hands are wet. And the two control access methods will be strengthened in the later stage, not less than touch screen and touch control operations.

4、 Function part - enjoy music

    O2 It is not just a sound box, but more importantly, it can bring better enjoyment of music. It's not important to listen to the radio or play music. You can listen to the sky and the sea while you roll it. You can listen to the lazy voice in the lazy sun, and you can listen to the rain to sing a nocturne. Radio, audio novels, and natural sounds are all music sounds. Listening to nature can be music.

     O2 You can directly transmit your mobile phone's songs to the speakers in a lossless way through DLNA. You can put lossless audio quality songs such as Netease Cloud music and qq music into the O2 cloud speakers to play, improving the sound quality of the sound source. In the future, O2 can take a taxi as a service platform for smart home, and this multiple interactive logical operation mode has great potential.

Having experienced the O2 app on Android and iOS systems, it is found that the functions and optimization of the Android app need further adjustment, while the iOS system is better than Android from functionality to optimization. In fact, apps are just a collection of content libraries. If you are not used to them, you can play music through DLNA without apps.

5、 Summary - Let the music play freely like air

     O2 Through good sound quality and a variety of control methods, the shackles of music are released, completely breaking the traditional way of music interpretation, and bringing music into life better. O2 has great potential in various control modes and functionality. If it can be further improved and optimized in the later stage, it will certainly get a good market evaluation. At present, the homogenization of products is still serious, but we can see the jumping momentum and differentiation potential of O2. It can be said that the thousand yuan file can be purchased without hesitation. Although the sound quality has yet to be adjusted, it is more playable.

6、 Suggestions

        1. Sometimes the touch screen will get stuck, and there have been crashes.

          2 The sound quality needs to be adjusted. The power of bass should not be fully exerted.

          3 10 sections of EQ adjustment shall be added as soon as possible, and more complete wind adjustment shall be set.

          4 First, we improved the Android app. Of course, both Android and iOS apps need to be improved.

          5 The touch screen is severely heated

          6 Speech recognition is poor

          7 、 When will the song search function of app be added

          8 The gesture function needs to be improved

          9 、 Airplay has not found that it is very important to improve its functionality.

After reading such a great review, please remember to give me a compliment. Complaining and praising are also very welcome!!!
