Disclosed is a wireless earset, including an antenna, a plurality of pattern matching circuits, a radio frequency switch circuit, and a wireless chip. The radio frequency switch circuit is electrically connected to one pattern matching circuit based on a control signal, and grounds the connected pattern matching circuit. After the wireless earset is activated, the wireless chip outputs different control signals to control the radio frequency switch circuit to be electrically connected to different pattern matching circuits to detect a received signal strength indication value for each channel within a preset channel range through the antenna electrically connected with different pattern matching circuits. When the wireless chip determines that a detection result generated by the antenna electrically connected to a currently connected pattern matching circuit meets a default condition, the radio frequency switch circuit maintains electrical connection with the currently connected pattern matching circuit. Therefore, the anti-interference ability is improved.
