13. A self-fitting device for location in an ear canal, comprising:
-
a body having a body ear end, an opposite body user end, and a shaft extending from the ear end to the user end; a resilient bladder joined with the body ear end and a chamber defined inside the resilient bladder where the chamber is in communication with the shaft and the resilient bladder has a wall portion and is deformable from an at-rest position to an in-ear position; the resilient bladder comprising a plurality of relief zones located in an inside portion of the wall portion of the bladder; and
,an elongate plunger located in the shaft, the elongate plunger having a plunger user end extending out of the shaft and away from the body ear end and an opposite plunger ear end in communication with the resilient bladder, wherein the elongate plunger actuates between the at-rest position and an insertion position to assist the resilient bladder in being deformed from the at-rest position to the in-ear position, and the resilient bladder has a first cross-sectional area in the at-rest position and a second cross-sectional area in the in-ear position, and wherein the first cross-sectional area is greater than the second cross-sectional area.
