TWS, means true wireless stereo. The implementation of this technology is based on the development of bluetooth chip technology. Technically speaking, it means that the mobile phone is connected to the main speaker, and then the main speaker is connected to the speaker through the Bluetooth wireless mode, thereby realizing the true separation of the left and right channels of the Bluetooth. When the slave speaker is not connected, the main speaker returns to the mono sound quality. TWS technology is used in the field of Bluetooth Headsets, so it has also spawned a new product - TWS Bluetooth headset.Since the TWS Bluetooth headset does not require a wired connection, the left and right earphones form a stereo system through Bluetooth, and the convenience of listening, talking, and wearing are improved.
Advantages:
1. True wireless structure, completely abandon wired troubles, and exercise more freely.
2. Various ways of use, both exclusive and shared, and can also be used as two earphones.

Educational Resources: Huanggang Education, Love Watching Cloud Education
At present, the release of the two-child policy has triggered a tantrum on the Internet. Education has naturally become a social contradiction. If the largest screen at home can be used as an educational window, this will undoubtedly combine entertainment and education into one. The most beautiful picture of learning is. Konka X80A built-in quick hands school application, including children's enlightenment, voluntary synchronization and social school education content of the three major plates, adapted to children of different ages, provide staged learning adaptation, to meet the learning needs of all family members.

In addition, the author tested the video support format of the TV through the security Bunny video test software. Out of the 30 videos tested, 27 are perfectly supported, only 3 are not fully supported, and 0 are not supported. The specific format is as follows: 
The most basic function of the TV is the color reproduction of the video. The Konka X80A has a unique 64-bit chip true color wheel engine technology that increases the color from 10bit 1.7 million colors to 12bit 686 billion colors, which is 64 times that of the competitive brand 10bit. Scanning, each pixel automatically adjusts the color of the picture in real time, just like the Mito Xiuxiu in the mobile phone. Each frame of the picture is processed through calculation. The richer color rendering force makes the picture more comprehensive, and the picture restoration is closer to the natural color. To the ultimate picture quality experience, create a hall-level visual effects for consumers. So how does the true reduction effect bring us amazing performance? Next, we enter the “Super HiVi Cast†test session. We will conduct more detailed tests on the Konka X80A TV's color transition, three primary color reproduction capabilities, and contrast to test the potential strength of this product. The test pictures were taken in the standard mode (for reference only when the screen shots were taken for multiple digital conversions after the shooting and the reader's display device performance was different). 
From the color ladder test chart above, we can see that the overall color transition of the Konka X80A is relatively smooth and natural. The split line between each color block is clearly visible. At the tip of the triangle, the gradient of the blue and green color patches is distinct, and the red color is slightly inferior. A little, but as a non-professional testing staff is only enough for daily viewing. The transition capability of the tricolor color gradation is blue> green> red, and it belongs to the middle of the LED LCD TV. 
Konka X80A TV's color saturation performance in place, colorful and not too bright, thanks to the exclusive true color 12bit color wheel technology and true color backlight (using the latest LED lights, RGB excitation by the blue LED light emitting white light, color gamut It can reach 78% -120%), Konka X80A curved TV perfect for the restoration of the three primary colors. 
Konka X80A surface TV is equipped with a 2K screen, purely from the resolution parameters, compared to the mainstream 4K product competitiveness slightly inferior, but given the "super high cost" product positioning and product actual significance, Konka X80A It is very competitive, which can be seen from the actual landing application of the video definition and 4K transmission bandwidth of broadcasting and TV: As far as the definition of broadcasting and TV videos is concerned, although the domestic HD channels have gradually emerged, they must achieve full HD weight. The long distance, even if the maximum HD can only reach the resolution of 1080P, so in a very long period of time or to SD as the dominant, in the living room 3-4 meters distance, Full HD and 55-inch combination can still be competent As for Internet broadcasting, there are two barriers that need to be breached. First, the 4K chip source problem is not enough to provide 4K resources, and secondly, bandwidth issues, in order to smoothly play 4K ultra-high-definition online video, At least 100 million fiber optical homes, in addition to the operator's overall transformation, the user's network costs are not cheap. From this point of view, 2K surface screen with 55-inch configuration, 4000R best curvature screen to give consumers iMax viewing experience, 4999 yuan Konka X80A undoubtedly in practicality advantage is still quite large.
2K quality restoration test
In the 4K mainstream market, will there be a big gap in 2K? The author through the dynamic screen test and static screen test, let you understand what the Konka X80A's picture quality clarity performance.
