The Bluetooth technology of Bluetooth earphones is mainly divided into three versions: Bluetooth 2.0, Bluetooth 3.0, and Bluetooth 4.0.
Bluetooth 2.0: It is the second version of Bluetooth technology, and its biggest advantage is power saving. A single battery can be used for about 50 hours. In terms of transmission speed, Bluetooth 2.0 can support a maximum transmission speed of 2Mbps, but the distance is only a few meters.
Bluetooth 3.0: is the third version of Bluetooth technology, with its biggest improvement in speed, supporting high-speed transmission (24Mbps) and long-distance (100 meters) transmission. At the same time, it also supports multi endpoint concurrency, meaning that the same device can connect to multiple other Bluetooth devices.
Bluetooth 4.0: is the fourth version of Bluetooth technology, with its most obvious feature being low power consumption, which can last for several months on a single battery. In addition, it also supports long-distance transmission, fast transmission speed, high security, and stable connection, gradually becoming the mainstream Bluetooth standard in the current market.
Overall, the Bluetooth technology of Bluetooth earphones is constantly being promoted and updated, which can meet the needs of different users and also make people's lives more convenient and efficient.
