Whether it is a smart TV or TV box, Bluetooth is one of its basic functions, but because of the existence of WIFI, Bluetooth seems to be less and less valued by users, but Xiaobian personally feels that the practicality of Bluetooth is still very strong. Using Bluetooth to connect a variety of peripherals can often greatly expand the entertainment of smart TV/TV boxes. Now it is important for you to check out some of the most commonly used and best features of Bluetooth. Function one: external handle to play the game Why TV games have been tepid? The main reason is that the TV remote control has a rushing control experience. There is no shortage of fun video games (which can be downloaded via the sofa butler). You can use the Bluetooth function to connect and enjoy the experience of the big screen game. Function 2: External Bluetooth Headset Using Bluetooth to connect audio may have been commonplace for a long time, but it is still somewhat new to connect headphones. Imagine being a god of the night, and the family has already gone to bed. It's time to wear a headset. Trying to catch up on the drama is also an extremely enjoyable experience. Function 3: External Bluetooth microphone K song Now that the smart TV function is more and more powerful, the addition of K-song function allows you to enjoy the feeling of KTV in the living room. At the same time, an external Bluetooth microphone allows you to sing without unlocking the wires and unlock various postures. If you are not satisfied with the content of the smart TV/TV box itself, you can install various video software through the sofa butler client and watch the whole network video as you like.
