Earphone box and wireless earphone assembly

The invention discloses an earphone box and a wireless earphone assembly. The earphone box comprises a battery, a charging circuit, a boost circuit and a control circuit, wherein the charging circuitis used for receiving external current to charge the battery; the boost circuit is used for boosting the voltage of the battery and outputting the voltage to an earphone so as to charge the earphone;the control circuit is coupled to the charging circuit and the boost circuit and used for acquiring an input current value of the charging circuit and an output current value of the boost circuit; first prompt information is output if the control circuit judges that the input current value of the charging circuit is greater than or equal to a first preset value when the charging circuit receives the external current; and second prompt information is output if the control circuit judges that the output current value of the boost circuit is greater than or equal to a second preset value when theboost circuit outputs curr
