ABSTRACT:
A detachable earmuff has an entrance separation which is normally biased closed and which is resiliently flexibly openable for receiving a headband of a headset for retaining the earmuff in covering relation to a users ear and an earphone held to the users ear by means of the headband. For biasing the entrance separation, overlapping parts of a frame structure extend inwardly from the outer end of the entrance separation. In one embodiment the earmuff frame may comprise a generally flat split plastic ring. In another embodiment the earmuff frame may comprise a resilient wireform which may be constructed in one piece.
