A clip-on microphone, also known as a lavalier microphone, is a small, discreet microphone that can be attached to clothing. It is commonly used in interviews, presentations, and video recordings to capture clear audio while allowing the speaker to move freely. The microphone is typically connected to a recording device via a cable or wirelessly. These microphones are popular in the fields of broadcasting, theater, and public speaking due to their convenience and unobtrusive design. They can be clipped to a shirt, tie, or collar, making them ideal for capturing sound without being visible, thus enhancing the overall quality of audio in various settings.
