There are many types of Bluetooth technologies for Bluetooth earphones, and the following are some of the main technologies:
1. Bluetooth 5.0 technology: Compared to previous versions, this technology has higher transmission speed, lower power consumption, longer coverage range, and better stability.
2. Terminal specific technology: This technology is widely used in smart devices such as Bluetooth earphones and smartwatches. Its difference from ordinary Bluetooth technology lies in its ability to dynamically match and negotiate connection parameters.
3. Bluetooth low-power technology: This technology is commonly used to connect low-power devices such as health monitors and sports devices. It can achieve high transmission speed and long-distance coverage while ensuring low power consumption.
4. Dual channel technology: This technology refers to simultaneously opening two Bluetooth channels, one for the microphone and one for audio output, which can achieve high-quality voice calls and audio playback.
5. Noise reduction technology: This technology is mainly used to reduce the interference caused by background noise on Bluetooth headphones, and can effectively improve the quality of voice calls and audio playback.
In short, the Bluetooth technology used in Bluetooth earphones is very rich, and the specific technology used depends on the specific application environment and requirements.
