A lavalier microphone, often called a lapel mic, is a small, clip-on microphone used primarily in interviews, presentations, and film production. Its compact size allows it to be discreetly attached to clothing, making it ideal for capturing clear audio without being obtrusive. These microphones are commonly used by reporters, actors, and public speakers to ensure high-quality sound while allowing freedom of movement. Lavalier microphones can be wired or wireless, providing flexibility in various recording situations.
