Today, Xiaobian makes a shopping guide for users who don't know how to choose a true wireless Bluetooth headset, and tries to let everyone choose a true wireless headset that suits them. Bluetooth: Give priority to Bluetooth Headphones with higher versions. When choosing Bluetooth Headphones, give priority to Bluetooth Headphones with higher versions. The differences between different versions of Bluetooth Headphones mainly lie in three aspects: transmission rate, energy consumption and transmission distance. Simply put, the higher the Bluetooth version, the better the experience. For example, Bluetooth 4.2 yuan version and Bluetooth 5.0 yuan version are common in the market at present. Compared with Bluetooth 4.2 yuan version, Bluetooth 5.0 yuan can bring twice the data transmission speed, and the transmission distance is twice as strong as that of Avengers: Endgame, thus reducing the loss of transmission efficiency. That is, more information can be transmitted to other compatible devices without establishing an actual connection. If you don't know which version of Bluetooth is the highest, there are two ways to confirm it. One is to search for relevant information directly on the Internet, and the other is to read more Bluetooth electronic products. The latest products are basically equipped with the latest Bluetooth. Waterproof: Choose different waterproof grades according to different needs. Bluetooth headphones are so small and have sound, so it is very difficult to be waterproof. Therefore, the general waterproof grade is high and the natural cost is high. If a few tens of dollars of headphones are waterproof with IPX7 yuan, it is basically impossible.
