To understand this new word, first of all, we need to understand the in ear Bluetooth headset. In order to have two earphones, the earphone cable is used for connection, while the real wireless cable is the same as the earphone cable.

In general, the real wireless adopts the design of the main and auxiliary headphones, that is, the main headphones are connected to the mobile phones, and then the auxiliary headphones are connected to the main headphones. But with the development of technology, now there is no difference between the main and the auxiliary ears. Both earphones are the same. But the left and right headphones are divided.

Because there are two earphones, which not only need to be connected to the earphones, but also need to be connected to each other, so the power consumption will be faster. At the same time, for the convenience of carrying two earphones, there is the design of earphone box. When buying, you don't need to pay attention to the size of the earphone, just pay attention to the size of the box.

From the perspective of configuration, many of them support Bluetooth 5.0. Compared with the previous ones, the connection is more stable and power saving. This is also a good way to improve the endurance and experience. Of course, the headset supports it, and the mobile phone supports it indefinitely. After all, it's a new technology. Apple's 8-generation technology is available, and Xiaomi's 6-generation technology is available. The main thing is to remove the headphone hole and add it.
