Headphones are a type of audio equipment that are worn over the ears to listen to music, podcasts, audiobooks, and other audio content. They are designed to provide high-quality sound and noise isolation, allowing users to enjoy their audio without being disturbed by external noise. Headphones come in a variety of styles, including over-ear, on-ear, and in-ear, and can be wired or wireless. Some headphones also include additional features like noise-cancellation, built-in microphones for making phone calls or voice commands, and touch controls for easy operation. Headphones are a popular choice for people who want to enjoy high-quality audio in private, whether at home, at work, or on the go.
