What is the transmission distance of Bluetooth earphones?

The transmission distance of Bluetooth earphones is influenced by various factors, including distance between devices, interference, obstacles, etc. Generally speaking, the transmission distance of Bluetooth headphones is around 10 meters, but in an obstacle free environment, they can be extended to 30 meters or more. Some new generation Bluetooth technologies, such as Bluetooth 5.0, can even achieve even longer transmission distances, up to around 100 meters. However, it should be noted that these numbers are for reference only, and the actual transmission distance may vary due to various factors. Therefore, it is necessary to determine the transmission distance of Bluetooth headphones based on the actual situation.
