This wireless microphone uses UHF signal transmission. The handheld microphone transmitter and receiver are made of metal. The redesigned circuit and high-quality chips optimize the signal transmission of sound and greatly reduce the loss of sound in wireless transmission. The system has a stable transmission range of 80m, and can reach 100m in an open area and without signal interference. The multi-functional receiver has a built-in SYNC automatic frequency search function, which can automatically search and locate safe frequencies in complex environments to avoid signal interference. The transmitter can be quickly paired through IR matching. This wireless microphone has a very high sound reduction degree, and is very suitable for singing at home parties, conference speeches, and even stage performances.
