Headphones, also known as headsets, are audio devices that are worn over the head and ears. They are typically used to listen to music, podcasts, or other audio sources. Headphones come in a variety of styles, from earbuds to full-size over-ear models. They can be wired or wireless, and some models even have noise-canceling features. Headphones are a popular choice for listening to music on the go, as they provide a more immersive experience than speakers.
