摘要： A length-adjustable collapsible headphone includes a headband comprising an upper section, a right lower section, and a left lower section, the upper section comprising an inner headband arm and an outer headband arm, the right lower section and the left lower section each comprising a scissor arm assembly having an inner scissor arm and an outer scissor arm, each of the inner scissor arms and the outer scissor arms comprising slide adjustment sub-assemblies. A pivot joint connects the outer headband arm to the inner headband arm so that the outer headband arm and the inner headband arm can rotate freely around an axis of the pivot joint. A left and a right pivot assembly connects respective inner scissor arms to respective outer scissor arms that are aligned with the axis of the pivot joint so as to maintain a common centerpoint allowing the headphone to collapse in a spherical motion to a space efficient closed state. At least one earcup assembly connects to the headband with a yoke using a swivel joint that allows the earcups assembly to yaw around the axis of the swivel joint.
