Abstract: An apparatus for stabilizing a concha style headset comprises a receiver attachment that couples to the body of the receiver of the headset, a flexible and resilient support member extending from the receiver attachment, and a concha stabilizer pad coupled to the end of the support member, such that the concha stabilizer pad contacts the upper concha under the antihelix of the ear with the receiver placed in the lower concha in front of the ear canal. The receiver attachment can include a foam ear cushion that covers the portion of the receiver that is placed in the lower concha, with the concha stabilizer pad and the flexible support member formed of a compressed cellular foam. Support ribs extend from the upper surface of the ear cushion along the surface of the support member and join the concha stabilizer pad.

Abstract: A telephone headset is connected to a telephone line through a interface module having programmable signal conditioning characteristics. The interface module is universal in that it can be programmed for use with many different headset or handset units. The interface module is automatically programmed through a multi-pin connector carried on the headset or handset connecting cable. The pin arrangement in the connector when plugged into a mating receptacle connector of the interface module produces binary input signals which can be decoded into programming signals for the signal conditioning circuit in the module.
