Method for Controlling Earphone Switching, Earphone, and Earphone System

An earphone, serving as a master earphone and being coupled with an electronic device and the other earphone serving as a slave earphone, and comprising:

• at least one processor;
• and
• a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, is operable with the at least one processor to:
• detect whether the earphone is put in a charging case;
• and
• switch the earphone to serve as the slave earphone and switch the other earphone to serve as the master earphone, upon detecting that the earphone is put in the charging case.

An earphone system, comprising a first earphone and a second earphone with only one of them being capable of coupling with an electronic device at a time, the first earphone being currently coupled with the electronic device and the second earphone and comprising:

• at least one processor;
• and
• a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, is operable with the at least one processor to:
• detect whether the first earphone is put in a charging case;
• and
• disconnect a first data transmission link between the first earphone and the electronic device and establish a second data transmission link between the second earphone and the electronic device, upon detecting that the first earphone is put in the charging case.
