Wireless headphones are a type of audio device that allows users to listen to music, podcasts or other media without the need for wires or cords. They use radio frequency technology to connect with devices like smartphones, tablets and computers, enabling seamless streaming of audio content. The lack of wires provides greater freedom of movement and convenience for users, as they can move around while listening to their favorite tunes without getting tangled up in cords. Wireless headphones come in various styles including over-ear, on-ear or in-ear models, with different features such as noise-cancellation, Bluetooth connectivity, and rechargeable batteries.
