Which type of microphone allows a subject to remain hands-free during demonstrations or interviews?

A lavalier microphone is designed specifically for scenarios where the subject needs to have their hands free, making it ideal for demonstrations or interviews. This type of microphone is small and can be clipped onto clothing, allowing the speaker to move around without holding a microphone. It provides convenience and mobility while capturing clear audio.

Unlike handheld microphones, which require the speaker to grip them, the lavalier's discreetness allows for a more natural speaking posture and interaction. Shotgun microphones, known for their focused directional pickup, are typically mounted on a boom or camera, which limits the subject's mobility. Dynamic microphones are versatile and used in various settings, but they also usually require being held or positioned close to the sound source, which isn’t suitable for hands-free operation.

By choosing a lavalier microphone, one benefits from clear audio capture while allowing the subject to express themselves freely, enhancing the overall quality and effectiveness of the video production.
