Not long ago in Love to play computer games On the platform of, I got a CoCase Demon Lover multi-functional mobile phone protection case. Our Demon Lover mobile phone case can match three against one, providing three services for iPhone 7 and iPhone 7 plus, including mobile phone case protection, Bluetooth transmission operation, and 3.5mm headset interface conversion! After this trial, I realized that at some point in the future, the CoCase multi-function mobile phone case of the Demon Lover on a specific model will redefine the meaning of the mobile phone case!

I received our product this Wednesday. After 2 days of experience and trial, the selling points and complaints of the product have been preliminarily understood! Now let me take you into the world of our magical multi-functional mobile phone case!

As highlighted above, our CoCase multifunctional mobile phone case is specially designed for the iPhone 7 and iPhone 7plus. Don't consider buying this artifact for other mobile phone models!

As we all know, the biggest problem with the new series 7 products of the iPhone is that the 3.5mm headphone interface on the traditional mobile phone has been canceled. The iPhone manufacturer said that this is the selling point of the product, which I dispute! To be honest, the new iPhone makes many people feel as if they are stuck in the throat. There is no serious injury, but it is not easy to use it in some places. The traditional 3.5mm headphone connector introduced above is one of them! The mobile phone with headphone interface that has been used for more than 10 years has suddenly disappeared, and you can definitely understand this feeling... Our CoCase multifunctional mobile phone protective case can make up for the shortcomings of Apple's new products, giving you a new feeling about Apple's mobile phones and mobile phone cases!

As shown in the figure above, after opening the packaging box of our product, you will find a manual of our CoCase multi-function mobile phone protective case, and then our gold master mobile phone case! According to the product introduction, I know that each model of our products has five colors to choose from: Chinese red, navy blue, coral green, wine red, matte black. The mobile phone case I got is frosted black. It feels good to hold it in my hand!

Now let's give a close-up of our products! There are three buttons on the back of the phone case. In the middle are the power on/off, pause, and play buttons. On both sides are the volume and up/down buttons. There is a small indicator light not far above the physical keys. On the top is the 3.5mm "headphone jack that has been missed for a long time. This jack can let enthusiasts retrieve your favorite headphones! The white space on the top and both sides allows you to protect your phone in all directions without affecting your daily needs such as taking photos, pressing keys, and charging below!

Our products adopt unique arc surface ultra-thin Design The minimum thickness of the bottom grip is 8mm. The frosting process makes our mobile phone case sweat resistant and slip resistant. The two processes perfectly match Bring you Control the super cool feeling. There is a thin sponge pad inside the front protective shell and a compact shell can form a perfect protection for our precious Apple 7 products. The ultra-thin design makes it impossible for me to see how many functions such as Bluetooth are inside our mobile phone shell!

Now let's take a look at our instructions. When we see our folding instructions in both Chinese and English, do you feel like the clearance discs of Elder Tang in Journey to the West? The reason why the manual is taken out separately here is that I want to emphasize once again that we must carefully read our manual. This is a big problem about the pairing of our CoCase product and the new iPhone 7 series Bluetooth product!

Speaking of Bluetooth pairing, I would like to highlight the selling points of our products. Our Bluetooth products use fast charging technology, which can be charged for 2 hours in 5 minutes. The battery has a capacity of 420mAh, which can be fully charged in about one hour. After one full charge, the battery lasts for 30 hours and has a standby time of 30 days. Do you think our Bluetooth products are very powerful? In fact, this is just the beginning. It has its own Lightning charging hole and supports Apple's original data cable. You can listen to music while charging. Can you imagine that?

Bluetooth pairing of products is also a big problem. Pairing in front of Apple phones before the system upgrade to 10.3.1 is like a piece of cake. For example, Apple 5S and Apple pay without upgraded systems, but before Apple 7 series products with advanced upgraded systems, the pairing speed is so long. First of all, we can't find our Bluetooth in my devices for a long time, Later, we found our Bluetooth signal but failed to pair twice. My colleague even said whether our product had a bug. Although we successfully paired with each other through our brothers' unremitting efforts and the guidance of the gods, I didn't praise the Bluetooth pairing speed of our product. I hope the manufacturer can carry out technical innovation in this area!

In fact, I have some controversy about the audio quality of Bluetooth transcoding! Our promotional selling point is "Bluetooth connected mobile phones, CSR top audio decoding chip, restore perfect stereo.", Mo Yanlin's "Love a little" audition I don't know whether it is the problem of our earphones or the problem of our audio decoding chip. The sound quality is not so perfect. This is a complaint point of the product. Can the sound quality be more perfect?

Of course, some of the selling points of the product are still worthy of praise and praise. Let me summarize the advantages of the product.

1. Adjust the volume directly on the protective case, switch songs freely, and support one button call.

Many high-end headphones on the market are Failed to pass MFI certification Wired control is connected to the iPhone to adjust the volume It's troublesome to cut songs. CoCase's Bluetooth controls the volume effectively, and the index finger can easily Complete the work of adjusting the volume and pausing the play, Give Way The large iPhone 7 Plus is better and easier to operate with one hand.

2. The built-in 3.5mm headphone jack outputs audio to make up for the shortcomings of Apple's new mobile phones. The built-in Lightning charging jack enables enthusiasts to retrieve their favorite earphones once again while listening to music while charging. In order to promote our products, I will take a photo and be prepared. Don't scare everyone!

3. Used by CoCase products Skin like silicone The material is exquisite, the curved surface design is round, smooth and ultra-thin, sweat proof, fingerprint proof, greasy and anti-skid, which is very powerful as a protective cover.

Of course, there are also some complaints about the product. For example, after the system is upgraded, the product Bluetooth pairing time is too long, and the audio quality converted from the Bluetooth product can be more perfect. I believe that there is still room for development in the future product technology innovation.

The current market price of our products is about 150, and the overall price performance ratio is very good. The same product price, the same price quality, our products as the combination of mobile phone shell+Bluetooth, is very good. A bunch of high-end earphones on hand waiting for the showy enthusiasts or IPhone 7 or plus new product users with 3.5mm requirements You might as well choose.
