This is a 4-in-1 wireless lapel microphone, designed for multi-person live streaming, interviews, and vlog shooting. It features 4 transmitters for simultaneous audio capture, paired with a Type-C receiver that plugs directly into phones/tablets for plug-and-play use. The built-in digital display shows real-time battery and connection status, with functions like noise reduction, reverb, and mute.
