Wireless transmission technology used in headphones

Bluetooth technology

Bluetooth, a wireless personal area network (Wireless PAN), was originally created by Ericsson and was later set by the Bluetooth Technology Alliance. "Bluetooth" was originally the name of the king of Denmark in the tenth century. It now takes the meaning of "unification" and is used to name the Bluetooth technology intended to unify the wireless LAN communication standard. After experiencing the six versions of 1.1, 1.2, 2.0, 2.1, 3.0, and 4.0, Bluetooth technology has developed a very stable and widely used user base, such as personal computers, digital cameras, printers, televisions, mobile phones, etc. You can find out the use of Bluetooth technology. 1.1 For the earliest version, the transmission rate is about 748~810kb/s. Because of the early design, it is easy to be interfered by the products of the same frequency and affect the communication quality. In 2.0, it is a modified version of 1.2, and the transmission rate is about 1.8 ~ 2.1M / s. The subsequent version 3.0 provides a more stable and high-bandwidth transmission with integrated 802.11 PAL, with a maximum speed of 24M/s, which is 8 times faster than 2.0.

So the emergence of 2.4GHz Wireless wireless transmission technology not only provides a new way for signal transmission, but also makes the bandwidth and distance of data transmission better.
