Abstract
A set of adjustable and convertible headphones includes a headband, an adjustment member, and an earpiece. The adjustment member is connected to the headband by a hinge; earpiece has a channel receiving the adjustment member and is slidably connected to the adjustment member. Rotation of the adjustment member with respect to the headband is spring-loaded in only one direction. The adjustment member and the earpiece in combination include a detent mechanism for resisting sliding movement of the earpiece with respect to the adjustment member. The adjustment member may be completely removed from the channel, thereby disconnecting the earpiece from the headband. The earpiece may then be replaced by another ear covering (e.g., an earmuff, an ear protector, etc.) as desired. The replacement ear covering may include an audio speaker, for example an audio/earmuff combination earpiece.
