preface

In 2016, Apple released two new Apple phones, iPhone 7 and iPhone 7 plus. Although these two phones were welcomed by countless fans around the world when they were released, there were still many complaints. For example, the 3.5mm audio interface was canceled and turned into a digital audio interface for lighting. Of course, this is also a technological progress. After all, it is a digital audio interface, At least the sound quality has been greatly improved, but there are many inconveniences. When listening to music with the iPhone 7 and the iPhone 7 plus, in addition to using the Bluetooth headset to connect the adapter to the 3.5mm audio interface, and the adapter can not be charged, but now it is good. Today I introduce a new product, which can completely solve these problems, That is the CoCase multi-function protective shell.

Product packaging

The packaging of the CoCase multi-function protective case is very simple. The white box has black words and the pictures of the four color mobile phone cases. Although it is simple, it looks good on the packaging. After all, the packaging is good for a mobile phone case.

product design

The color I got is black. There is a layer of black velvet on the inside of the phone case, which can effectively protect your phone from being scratched. Although it is made of plastic, it feels good in the hand. It feels very delicate to touch, and it is also comfortable to hold. It is very correct in terms of workmanship, and the design is relatively simple and generous. There are three buttons on the back of the case, It's needless to say that you can see what the function is. The only pity is that the upper part of the phone case protrudes several millimeters in order to make a 3.5mm audio interface, which makes the phone unable to be completely flat. But from the design point of view, the designer has tried his best. After all, there is no perfect thing. You can't have both fish and bear's paw.

Product Functions

Although today's introduction is a phone case, it is different from the traditional phone case. After all, it is a phone protective case with Bluetooth function and 3.5mm audio interface. The difference between this phone case and other phone cases is that there is a 420mA battery inside this phone case. The latest version of Bluetooth 4.1 has an effective distance of 10 meters. Theoretically, it can listen to music and talk for more than 30 hours continuously, Bluetooth has voice broadcast throughout the whole process. For example, when you turn on or off the phone, there will be voice prompts, which is very convenient and easy to use. Put the phone into the phone case, long press the power button on the back, and then turn on the Bluetooth of the phone to start pairing. Pairing between the phone case and the phone is very simple. In the power off state, long press the power button on the back for about 5 seconds, the blue and green lights will alternate, and the pairing state will enter. After the pairing is successful, you can start to experience. The indicator lights have three colors, namely red, green, and blue. All colors and the number of flashes have different meanings. You can understand it very well just by looking at the manual. I won't say more here.

summary

On the whole, the CoCase multi-function protective case can solve the problem we mentioned before. After all, 3.5mm earphones can be used. Most of the earphones on the market are 3.5mm earphones, or Bluetooth earphones. With such a product, some problems will be solved. Of course, some problems still need to be improved by the manufacturer. After all, there is no power display, I don't know how much power is left, even if the power doesn't flash a red light, and the CoCase multi-function protective case doesn't support the remote control on the headset, but the buttons on the back of the phone case can be used normally. Is that the design? But generally speaking, it is very good. After all, it can solve the problem that the iPhone 7 and the iPhone 7 Plus do not have a 3.5mm audio interface. Other small problems can no longer be considered a problem. Moreover, the price of 158 is also quite reasonable. It is absolutely worth the price. Finally, I hope our manufacturers can improve this product and make it better.
