ABSTRACT:
A spring biased earmuff, having a flexible and generally ring-shaped frame (2) covered on an outer side and on an inner side by a fabric material (3), the frame being flexible between an open position wherein an ear may be inserted through an elongate hole (4) from the inner side of the earmuff such that the earmuff covers the ear on the outside and on the back side, and a snap on position wherein the frame exerts a biaising force for holding the earmuff to the ear, the frame having a frame front member (5) and a frame back member (6). An earphone (L) is supported by the frame, the ear phone being covered by the fabric material on the outer side of the earmuff. The earphone is removably attached to the frame (2) in a portion thereof, from where the earphone is supported outside the auditory canal of the ear in a user position of the ear muff. The frame exerts a biaising force on the earphone, away from the ear, in the hold position of the earmuff.
