Abstract
This headset comprises two earphones (10), each comprising a generally ring-shaped, flexible circumaural or supra-aural pad (16), mounted on a shell (14) receiving a transducer (30). The headset comprises an electronic circuitry powered by a battery, and a battery recharging circuit connected to at least one inductive-coupling recharging coil (20). The coil is housed in a pad (16), and it is housed in a region of the pad (16) that is close to an outer limit plane, on the wearer side, of the envelope (16a, 16b) of the pad, for example near a seam (C) between two portions (16a, 16b) of an envelope of the pad.
