preface: The technology of modern society is more and more developed, and people's life is more and more comfortable. The birth of various products has brought convenience to people's life. The comfortable and convenient life is supported by more new equipment. When people get used to this life, they will contact more and more equipment. When changes occur suddenly, people will become uncomfortable. For example, the iPhone cancels the 3.5mm headphone jack. People who are used to wearing earphones are at a loss, and even give up using the new iPhone. Regardless of whether this change is good or bad, as a product that links the two, the emergence of the CoCase multifunctional protective shell of the Demon Lover makes people shine.

Before the release of iPhone 7, everyone heard a news. The 3.5mm headphone interface will be removed from the new Apple mobile phone, which makes some Apple users who like to listen to music on their mobile phones complain. When the iPhone 7 comes, more inconvenience will follow. In particular, you can't listen to music while charging.

The appearance of this product is formally based on solving this problem. It is very creative and combines the Bluetooth headset with the mobile phone case, bringing convenience to people's lives.

Body: First of all, thank you Love to play computer games Thanks to the unique mobile phone case provided by Demon Lover.

As shown in the figure above, the packaging and components of the CoCase multi-function protective case are very simple and generous. After opening, you can see the main body of the phone case, the user manual, the warranty card, etc.

Carefully observe the main body of the mobile phone case and find that the workmanship is really excellent. In the process of use, I also found six features of this phone case. Let me talk about them~

Feature 1: Good manufacturing process, black matte, very textured

Since I got the black matte version (I personally asked for the black version, which also met my requirements, hey hey), the phone case feels very textured, anti slip and very grand.

Feature 2: The body is perforated and the fit is very good

The camera, volume key, and holes in various places are very close to the phone, so there will be no obstruction or discomfort when using it. There is no burr on the whole shell body. One meter smooth at round corners and other places~

Feature 3: The shock proof layer made of special cotton wool inside the mobile phone case

The shockproof layer with cotton wool texture can effectively shockproof and is also beautiful. By the way, it covers the battery and other parts below. Extremely good design.

Feature 4: Excellent operation design

There are three buttons on the shell. The manual explains in detail how to use the three buttons to quickly listen to songs, answer and make calls. In this way, even if the headset is not equipped with the remote control function, you can still use the phone case to switch songs and increase or decrease the volume.

Feature 5: very thin

To my surprise, I thought that a mobile phone case with its own battery could be charged, with Bluetooth function and adapter function. Then this phone case must be very thick and heavy. But when I actually got it in my hand, I felt that compared with other mobile phone cases, it was not particularly heavy. As can be seen from the picture, the phone case is very thin.

Feature 6: Lightning is used in the charging hole

Needless to say, if a special iPhone case uses other types of data cables, I think that unless the designer is confused, it will not be designed like this.

It is difficult to have perfect things in the world. It is because of the shortcomings that people can improve and make progress.

In the same way, this phone case has also found the following three shortcomings in daily use. I also hope that the next generation of products will be improved.

Disadvantage 1: The phone case is easy to open by mistake

During the use of the phone case, the three buttons feel very good. However, there seems to be no protection against accidental contact. In my own use process, I often encounter this situation: the phone is put in the bag, in the pocket, and then unknowingly, the phone case opens!!!!! It not only wastes power, but also reduces user experience. Therefore, the hardness of the key can be appropriately increased. Lower false touch. Or change the power on mode to click the power on key three times in succession to power on. In this way, the occurrence of false startup can be greatly reduced.

Disadvantage 2: The headset is disconnected, and Bluetooth is constantly

This is a very, very, very serious shortcoming. Yes, I used 4 "very" to show its importance. In use, the headset was unplugged, but the Bluetooth was not disconnected, and the voice was still in the phone case (everyone who has used the Bluetooth headset should understand this statement), resulting in no sound even when using the external amplifier. This is very embarrassing. Reminders that people will miss a lot of news. I hope it can be improved to make the phone case more intelligent. After the headset is unplugged, the Bluetooth function can be detected and disconnected, or other intelligent solutions can be used.

Disadvantage 3: It's awkward to listen to songs when charging

During the normal use of mobile phones, the charging is generally at the lower part and the music listening interface is at the upper part. For the sake of reasonable design of the phone case, the headphone jack and the charging interface of the phone case are arranged on the top. This is a bit against people's usage habits. Suppose I play with my phone while listening to music while charging the phone case, then dragging the phone with a cable above the phone will greatly reduce the pleasure of playing with the phone. (especially the charging line). In addition, if the mobile phone is charged, the top two and the bottom one, OK, I choose the dog belt. Therefore, it is suggested that the headphone interface should be on top and the charging interface should be on the bottom. Or the headset charging interface is below. In addition, it can also be designed to integrate with the mobile phone charging, so that the charging interface of the mobile phone case and the mobile phone charging interface can be combined into one.

To sum up, this product is still a very good product. I will focus on the advantages and disadvantages:

Feature 1: Good manufacturing process, black matte, very textured

Feature 2: The body is perforated and the fit is very good

Feature 3: The shock proof layer made of special cotton wool inside the mobile phone case

Feature 4: Excellent operation design

Feature 5: very thin

Feature 6: Lightning is used in the charging hole

Disadvantage 1: The phone case is easy to open by mistake

Disadvantage 2: The headset is disconnected, and Bluetooth is constantly

Disadvantage 3: It's awkward to listen to songs when charging
