Abstract

A system and method for a collapsible headphone unit is provided. Generally, the system contains a first extendable sidepiece and a second extendable sidepiece, both rotatably attached to a top member. The first extendable sidepiece is attached to a first earpiece, and the second extendable sidepiece is attached to a second earpiece. Each earpiece has an open portion that fits against the ear of the user. The first and second extendable sidepieces may be extended, thereby allowing the first and second earpieces to pivot, resulting in the open portions of the first and second earpieces being directly opposed, and allowing the first and second earpieces and the first and second extendable sidepieces to fold upward toward the top member.
