BACKGROUND
This background section is provided for the purpose of generally describing the context of the disclosure. Work of the presently named inventor(s), to the extent the work is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Headsets have many purposes. They can be used for enjoying music, making phone calls, or simply protecting the ears from noise or the cold. One sought-after feature of a headset is its ability to collapse into a more compact shape for more convenient storage. Many solutions have been implemented. One class of solutions employs hinges or pivots that allow the headband to fold or rotate into a more compact shape. Another class of solutions allows the earpieces to rotate with respect to the headband to achieve a more compact shape. These solutions tend to be unwieldy or overly complex, and fail to preserve the pure and simple aesthetic form of the headset sought by the designers and consumers.

The user-operable controls 920 may include buttons, slide switches, capacitive sensors, touch screens, and the like.
A number of implementations have been described. Nevertheless, various modifications may be made without departing from the scope of the disclosure. For example, the hinges/pivots may be hidden from view by a cover made from cushions, covers, or the like. The hinges/pivots may be implemented as friction hinges. The hinges may be implemented as living hinges. For example the faceplate, flanges, and hinges may be formed from a single piece of material where the hinges are thin enough to flex. The earpieces may be implemented with detents that hold the earpiece in the folded and/or unfolded position(s) but otherwise permit folding and unfolding of the earpieces. The earpieces may include a motor to operate the faceplates and flanges, for example in response to a user-operable control, automatically on connection with another device, on establishment of a link with a link partner, or the like. Accordingly, other implementations are within the scope of the following claims.
