Yes, Bluetooth headsets can only be paired with one Bluetooth device, they identify each other through the code, when you bind it to a mobile phone, it will store its identification code in the earphone. If you change to a new earphone, you can store the new identification code directly by re-matching the code, and you don't need to delete it.

The Bluetooth transmission distance is theoretically 10 meters, but the impact of quality, workmanship, interference, power, shielding, distance, and blocking can be guaranteed by four or five meters. If it's a wall, it's only two meters away.

Advantages of Bluetooth: wireless has no wire trouble, is widely used, can communicate with Bluetooth mobile phones, Bluetooth computers, Bluetooth ***, etc., and the power consumption is not large, safe and environmentally friendly, good confidentiality.

Disadvantages: the sound is generally small (in order to save power, after all, such a small volume cannot be equipped with a large battery), most of them are mono (there are also stereo ones, but the stereo ones must have a wire connected to the other side of the earphone, which is inconvenient), and then it is necessary to charge it frequently, and the standby time is not long.

Advantages of wired headphones: they do not need power supply, the sound quality is good, they can talk for a long time, and they are basically stereo.
