Our Opinion

A very practical solution if you already have a microphone you're comfortable with and want to use it wirelessly without purchasing a complete system with another microphone. Its direct XLR connection makes setup straightforward, while the 4 channels and up to 35-meter range provide enough flexibility for stage performances, rehearsals, presentations, or small events. Especially suitable for dynamic XLR microphones where freedom of movement and cable elimination are priorities on stage.
