Disclosed is a wireless headset including an antenna, a plurality of pattern matching circuits, a radio frequency switch circuit, a wireless chip, a port matching circuit matching the impedance of the wireless chip, an antenna matching circuit matching the impedance of the antenna, a circuit board including a feeding point and a grounding point, a feeding connector and ground connector. The plurality of pattern matching circuits respectively match the impedance of the antenna. After the wireless headset is activated, the wireless chip outputs different control signals to control the radio frequency switch circuit to be electrically connected with the different pattern matching circuits, to detect a received signal strength indication of each channel within a preset channel range through the antenna electrically connected to the different pattern matching circuits. When the wireless chip determines that a detection result meets a preset condition, the radio frequency switch circuit is kept electrically connect
