Handheld microphones are portable audio devices designed for capturing sound. They are commonly used in live performances, interviews, and public speaking events. These microphones are typically held in the hand, allowing the user to move freely while speaking or singing. Most handheld microphones operate using either dynamic or condenser technology, each offering different sound qualities. They often connect to audio systems via cables or wirelessly, making them versatile for various settings. Popular brands include Shure and Sennheiser, known for their reliability and sound clarity in professional environments.
