Headphones
Headphones are personal audio devices worn over or in the ears to listen to sound from a source like a phone or computer without disturbing others. They consist of two small loudspeakers, known as earphones, connected by a band and a wire, or wirelessly via Bluetooth. Different types of headphones exist, varying by fit (over-ear, in-ear), acoustic design (open-back, closed-back), and features like noise cancellation or water resistance.
