Abstract
A charging case for a plurality of headsets is disclosed. Each headset includes two headphone units connected together in opposing relationship along a diametric axis by a headband. Each headset contains a battery and a charge receiving circuit coupled to the battery. The charging case comprises a portable, cylindrically shaped carrying case and a charging station contained in the carrying case. The charging station includes a plurality of charging receptacles and a charge distribution circuit. The charging receptacles are disposed in a circular pattern about a center area and are configured to support the headsets, respectively, in an orientation where the diametric axes of the headsets are positioned radially in the circular pattern. The distribution circuit distributes electricity to the charging receptacles. At each receptacle electricity is transferred to the charge receiving circuit of a headset when the headset is in the receptacle, to charge the battery of the headset.
