Trial Report of Love Demon Guest CoCase Multi functional Protective Shell

On September 8, 2016, Apple released the latest iPhone 7 and iPhone 7 plus, which attracted much attention. Both phones have revolutionized the 3.5mm audio interface and turned it into a digital audio interface for lighting. The advantage of this is that compared with the 3.5mm analog audio interface, the lighting digital audio interface can provide higher fidelity output. Another "advantage" is that it can induce you to buy expensive "airpods" wireless Bluetooth headsets. Of course, there are too many disadvantages. In a short time, we really can't adapt to the days when there is no 3.5mm interface. Or use Bluetooth headset, which is easy to lose after a long time; Or you have to use the official adapter to convert the 3.5mm interface, and the 3.5mm interface cannot be used for charging if the adapter cannot be charged. Most of the earphones in our hands are 3.5mm connectors, which have no use for a while.

What's the best of both worlds, which can not only solve the problem of charging and listening to music, but also continue to use our 3.5mm interface headphones?

The answer is yes. That is to solve all the above problems at one time by using the CoCase multifunctional protective shell.

1、 Packaging Appearance

The outer package of the Demon Lover mobile phone case is a simple white box with English words on it: smart protective case for iphone7 plus， The translation is "intelligent protective shell for iphone7 plus". There are four colors printed in the middle, namely "mat black matte black", "navy blue", "coral green" and "claret red".

On the lower left corner Love to play computer games LOGO label of.

After opening the sunspot, there is a manual and a CoCase multi-function protective shell. My phone case is matte black for iPhone 7 plus.

There is a circle of foam under the box to protect the phone case from damage.

Carefully observe the top of the protective foam, and you will find a strip foam that can be removed. I didn't know what this was at first, but later I knew it. This position should be a adapter for converting different headphone systems. Unfortunately, we didn't have it in the packaging for this trial.

2、 Appearance of mobile phone case

Open the white protective plastic bag and take out the protective shell. The appearance of the protective case is made of frosted material, which is very comfortable to feel. The most obvious thing on the back is that there are three physical buttons in the center. On the left is the volume increase and the next song. On the right is the volume down and the previous song. In the middle is a switch button, which can be used to open, close, pair, answer, hang up and reject, play and pause.

There is also an obvious place above the phone case, that is, there is a cylindrical protrusion with a 3.5mm interface, and there is an inconspicuous hole directly below the protrusion. This hole is the indicator light.

The front of the protective case and the place where it contacts the back of the phone are covered with a layer of black velvet material, which can protect the back of the phone very well and will not wear with the protective case.

The whole protective case is made of frosted material. There are two ports on the top, one is the lighting port for charging, and the other is the 3.5mm headphone port.

The bottom design is very thin, leaving a gap for the charging interface to prevent blocking the charging head.

3、 Mobile phone installation

Put the iPhone 7 plus into the phone case. The black phone is matched with the black case, which is a perfect match.

The back camera position opening is accurate, and the dual camera, microphone and flash are on the horizontal centerline of the opening.

There is no 3.5mm headphone jack at the bottom of the iPhone 7plus, which is really frustrating. Fortunately, with the Demon Lover mobile phone case, the 3.5mm headphone hole has been restored.

The protective case protects the four corners of the phone very well, covering all the corners.

The side vibration switch and volume increase/decrease, as well as the position of the power switch and the opening are also very accurate.

Take a close-up of the camera part and the 3.5mm headphone plug part.

Very beautiful. The protective case is also very thin.

The Iphone7 plus is equipped with a Demon Lover protective case, which makes it high-end and grand.

Look at the effect of inserting headphones. Iphone 7 plus is finally able to "plug in" ordinary headphones.

The connecting part between the earphone and the protective case is molded with thick plastic, so there is no need to worry about damage and looseness.

4、 Protective shell parameters and use methods.

There are three languages in the manual, namely English, Traditional Chinese and Simplified Chinese.  

The Bluetooth version of the protective case is the latest version 4.1, the chip is CSR8635, and the effective distance is 10 meters. Built in 420 mAh battery. You can talk continuously or listen to music for 30 hours.

You should know that the battery of an ordinary Bluetooth headset is only 40-90 mAh, while the built-in battery of the Demon Lover mobile phone case reaches 420 mAh, so it can provide 30 hours of ultra long playback time, or a month of standby time. During the charging test, the maximum input current reached 0.4A. Calculated according to the charging current of 1C capacity, the battery capacity was at least 400mA. It can be seen that the battery capacity did not shrink.

Bluetooth supports voice broadcast status information. Power on and power off will prompt "power on" and "power off" voice. If the pairing is successful, it will prompt "successfully paired". The phone case will be disconnected when it is far away from the phone. The voice prompt "disconnected" will be displayed. When it is close to the phone, it will automatically connect with the voice prompt "connected".

It's easy to pair the case with the phone. 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.

At this time, the mobile phone will search for "BClouds for i7" devices. Click to pair.

After pairing, it shows that it is connected, and it can be used normally.

After the pairing is successful, there is no need to pair again in the future. Long press the power key for 2 seconds to start the machine, and then long press the power key for 3 seconds to shut down the machine.

When there is a call, press Connect and then Hang up. Or long press to reject a call.

Volume up or down Short press is to increase or decrease the volume once, long press is to continuously increase or decrease the volume. Double click when you want to cut songs.

During the call, you can adjust the call volume through the back button.

The status indicator has three colors, red, green and blue. The status of the device can be known according to different flashing states. For details, see the introduction of indicator lights in the manual.  

After testing, the phone case supports not only the iPhone 7 plus, but also the iPad, Android and other mobile phones.

Successfully paired with iPad.

It can also be paired with ordinary Android phones.

Before using the CoCase multi-function protective case, I always used the Nokia BH-214 Bluetooth headset. Because the Bluetooth headset and the mobile phone are separate, I often take away the mobile phone and forget about Bluetooth, or the mobile phone is no longer around with Bluetooth. After a long time, Bluetooth automatically turns off and has to be restarted, which is too cumbersome. This time my BH-214 can finally rest.

5、 Some points to be explained

1. Our trial version of the Demon Lover protective case does not have a adapter this time. Since the Demon Lover protective case itself only supports the CTIA international standard, if you use the OMTP national standard earphones, there will be a loss of sound. The official retail version will be equipped with adapter conversion.

2. The only drawback is that the phone case does not support the function of displaying Bluetooth power. How much power is left depends on your own feelings.

3. According to the test, the phone case does not support the remote control on the headset. All operations must be performed by pressing the physical button on the back of the phone case, but it supports the microphone.

6、 Summary

The CoCase multi-function case is a very practical intelligent case. It can not only be used as a protective case for the iPhone 7 plus, but also be paired with the iPhone 7 plus through Bluetooth to achieve the function of Bluetooth headset. The most important thing is that the iPhone 7 plus has canceled the 3.5mm headphone interface, so the case can transmit sound to the 3.5mm headphone interface, It makes our ordinary earphones useful and really solves the problem of users' pain points. It can listen to music while charging. The phone case has high battery capacity, long standby time, and is always with the phone, ensuring the stability of the connection, and will not be disconnected due to the distance. One multi-purpose shell is the essence of the CoCase multi-function protective shell for Demon Lover, which is worth owning by every iPhone 7&7plus user.
