Abstract: Headphone system including two ear cups (105a, 105b), a headband assembly (110), an interface system (115) and a control system (120). Each ear cup (105a, 105b) includes an ear cup enclosure (205a, 205b), an ear pad assembly (207a, 207b), a speaker system (805) and a hinge assembly (700). The hinge assembly (700) is disposed within the ear cup enclosure (205a, 205b) such that it is not visible from outside the ear cup (105a, 105b). The headband (110) assembly connects with each of the ear cups (105a, 105b) via the hinge assembly (700). The interface system (115) includes at least one interface and a plurality of input source buttons (202, 204, 206) disposed on at least one of the ear cups (105a, 105b). Each of the input source buttons (202, 204, 206) is configured for selecting a source of audio data received via the at least one interface.

Abstract: A hub and a camera mount configured to support a video camera. The camera mount and hub are detachably mountable with respect to each other in any of at least two different configurations, preferably with adjustability in at least one configuration. In some embodiments, the camera mount includes a first structure including a retainer and camera support, a slide translatably mounted to the first structure, and a foot having a first end pivotably attached to the slide. The retainer is shaped to engage a surface of an object to which the camera mount is to be mounted. Other aspects are a camera mount, and a camera mount alone. Optionally, in one configuration the hub is mountable to a wall or other surface.
