A wireless microphone is a device that transmits audio signals from the microphone to a receiver without using cables, allowing greater freedom of movement for the user.
Features and Uses
Wireless microphones are popular for interviews, vlogging, podcasts, live performances, presentations, and other content creation scenarios. They typically consist of a transmitter (attached to or built into the microphone) and a receiver that connects to the recording or amplification system. Modern wireless microphones often feature high-quality built-in microphones, intelligent gain control, and long battery life for mobility and convenience.
