Abstract: A method for communicating between a wireless earphone and a charging case, a charging case, a TWS earphone and a TWS earphone system are provided. In the method, in response to a case opening signal, the earphone case I/O controlling module is controlled to set an operation attribute of the first I/O interface as a communication interface. A predetermined negotiation signal is transmitted to the wireless earphone via the first I/O interface. It is determined whether a negotiation confirmation signal corresponding to the predetermined negotiation signal is received from the wireless earphone via the first I/O interface. In a case that the negotiation confirmation signal corresponding to the predetermined negotiation signal is received from the wireless earphone via the first I/O interface, the charging case enters into a communication mode for communicating with the wireless earphone.
