摘要：
A stereophone includes a pair of temporal pads which connect to a headband and engage the user's head above each ear. A support arm pivotally connects to each temporal pad and supports an ear cup over the user's ear. A locking mechanism enables the support arm to be positioned in a number of operating positions or swung to a transport position.
