Abstract: A wireless earphone includes a pair of wireless earphone bodies, each having an upper case and a ferromagnetic lower case detachably connected with each other. The upper case is provided with a first circuit board and a magnet. The first circuit board is electrically connected with a wireless module and a speaker. The ferromagnetic lower case is provided with a second circuit board and a rechargeable battery. One end of the upper case is provided with a first pogo pin electrically connected with the first circuit board. The ferromagnetic lower case is provided with a second pogo pin opposite to the first pogo pin and electrically connected to the second circuit board. The first pogo pin can couple with the second pogo pin so that the ferromagnetic lower case can magnetically couple with the upper case and provide electricity to the first circuit board.
