Wireless microphones are devices that capture sound without the need for cables. They use radio waves to transmit audio signals from the microphone to a receiver, allowing for greater freedom of movement. This technology is commonly used in live performances, presentations, and broadcasting. These microphones come in various types, including handheld, lapel, and headset models. They are popular among musicians, public speakers, and television hosts because they eliminate the hassle of wires, making it easier to engage with an audience. Wireless microphones typically require batteries and may have a limited range depending on the model.
