A headphone that is, in one embodiment, collapsible into a fully collapsed, self-protecting form factor, and includes a headband that mechanically interconnects the two earpieces and fits around the head when worn. The headband can optionally include one or more telescoping linkages to allow it to collapse in length. The headband is attached to each of the two earpieces by two hinges in one embodiment: one hinge connects the headband to an intermediate part, which exists between an earpiece and the headband, another hinge connects the intermediate part to its corresponding earpiece. The wrapping of the headband around the two earpieces can leave no part extending outside from the structure which resembles a hockey puck in one embodiment.
