Self-fitting device for location in ear canal, including first end portion joined with second end portion. First end portion including first resilient bladder and first chamber of fluid and second end portion including second resilient bladder and second chamber of fluid. The bladders are in communication via the chambers. First bladder is deformable between at-rest position to in-ear position to insertion position such that first bladder has first cross-sectional area in at-rest position, second cross-sectional area in in-ear position and third cross-sectional area in insertion position. First cross-sectional area is greater than second cross-sectional area which is greater than third cross-sectional area. Second bladder is deformable to cause first bladder to be deformed from at-rest position to insertion position before device is located in ear canal.

Self-fitting device for location in an ear canal

A hearing protection device for a human ear. The device has an arm that clips about the pinna. A plug member caps or enters ear canal. The device is biased to provide some force against the plug member so that is stays in position during use. An optional handle may be provided to assist with temporarily pulling the plug member away from the ear canal or providing adjustment. The device may be adapted for use as an ear phone.
