摘要:
The earmuff of the present invention comprises in combination: an adjustable temperature switch, location of a power supply such as a battery inside the earmuff housing, a top frame enhanced to provide a “head gripping” feature, earmuff pads constructed to conform to the ears that are not flat but have some concavity to assist in wearers comfort and use when moving around. The inner muff is constructed of a soft-foam and further includes a slot that enables the concurrent use of ear phones. The heating element is a plate designed to conserve battery current with adjustable temperature and a circuit design focused on conserving battery current. The plastic frame provides a head gripping feature designed to eliminate unnecessary weight and to maximize air flow that will prevent sweat and moisture buildup around the ears.
