Abstract
Headphones can be configured such that back surfaces of the speaker housings can be coupled to form a loop enabling users to wear the headphones around their necks when the speakers are not in use. In various embodiments, faces of the respective speaker housings may comprise asymmetrical, complementary surfaces. In such embodiments, the users can distinguish between the speakers intended to correspond with respective right and left stereo channels by tactile feel. In some embodiments, the interlocking of the housing structures can be achieved by magnetic force to maintain the coupling when the speakers are not in use but can be decoupled by the user without undue effort. In some embodiments, the speaker housings are configured to constrain the housings to a specific orientation when mated.
