Headphones are a type of audio device that allow individuals to listen to audio privately without disturbing others. They consist of two ear cups that cover the ears and are connected by a headband that goes over the head. The ear cups contain speakers that deliver audio directly to the ears. Headphones come in various designs and types, including over-ear, on-ear, and in-ear models. They are commonly used for personal audio listening, including music, podcasts, and audiobooks. Some headphones also feature noise-canceling technology that reduces ambient noise for a more immersive audio experience. Headphones are also popular for professional use, such as in audio production and monitoring, and for gaming and virtual reality applications.
