Users who use iPhone 7 and 7 Plus have a small embarrassment. If there is no Lightning interface headset with iPhone in the outdoors, especially on the journey, it is impossible to listen to music with the ordinary 3.5mm interface headset. I have personally encountered this situation countless times, and I am almost mad every time I encounter this situation.

This time, I was lucky to receive Love to play computer games The CoCase multifunctional protective case provided by the Demon Lover has the protection function of the mobile phone case, Bluetooth transmission function, 3.5mm headset access, and independent power supply. This protective case, which integrates many "black technologies", can completely solve this embarrassment. Let's experience the special features of this protective case.

The case is black, which matches the matte black iPhone 7 Plus in my hand. This protective case has four colors: navy blue, coral green, wine red and matte black, which can satisfy the aesthetic effect of all kinds of people. The protective shell has a good hand feel. The coating of the shell not only makes it look soft and moist, but also makes it feel comfortable to touch with fingers, and can effectively avoid the generation of fingerprints.

The thickness of the mobile phone case is slightly thicker than that of the ordinary case, which is also due to the internal integration of various modules such as batteries. However, it doesn't feel too thick in the hand. Instead, it has a warm and smooth touch, which fits well with the mobile phone.

Sponge is used inside the phone case to reduce the friction between the case and the body, which also greatly reduces the risk of broken screen after the phone accidentally falls. This is really very carefully designed.

There are three buttons in the middle of the back. They are the previous song, the playback pause and the next song. The damping design of the button is very light and soft, and the feel of pressing is very good. The gap between the key and the protective shell is very balanced, and the setting position is also very reasonable. Under the condition of single hand holding, you can easily operate the three keys with your fingers.

The protruding part on the top is the 3.5mm headphone jack, and beside it is the Lightning interface. You can use the iPhone's own charging cable to charge the phone case without changing the charging cable. This is also the biggest highlight of this protective shell. The protective case can be fully charged in about two hours.

There is a small hole in the middle, which is the indicator light of the phone case. Different reminding effects can be achieved. Such as power on, Bluetooth connection, charging, etc.

The blue light flashes, indicating that the device is not connected; The blue light is always on, indicating that the protective case is being charged;

If the green light flashes 3 times continuously, it indicates that the phone and the protective case are connected;

The green light flashes, indicating that music is playing; The green light flashes slowly, indicating that the call is in progress; The green light is always on, indicating that the charge is full;

If the blue and green lights flash alternately quickly, it indicates that the protective case is in Bluetooth pairing; If the red light is on, the power of the protective case will be very low, indicating that you need to charge.

The key openings on both sides are designed very precisely, but it may take a little force to press the side keys during use. Because of the thickness of the shell, the thickness of some of the openings is almost the same as the height of the body keys.

In general, it is very good in use. The sound quality is the same as that of the Lightning interface headset. In operation, the remote control button attached to the headset cannot be used. Instead, use the control button behind the shell.

After actual testing, this phone case can listen to music for more than 2 hours continuously when fully charged, and can support most short and long distance use. The charging speed is also very fast. Because of the built-in 420mah battery, it can be fully charged in about one hour.

I also found a new way to play in the use. I put my iPhone anywhere at home, and put the shell beside me. Because it is Bluetooth transmission, I can use it to make calls or listen to music. I can walk around without touching my iPhone.

In general, in the market environment with a wide range of mobile phone cases, the CoCase multifunctional protective case of Demon Lover has taken a new and innovative path. The price of 158 yuan is slightly higher, but in order to solve the problem of 3.5mm headphone jack, what's more expensive?
