Claim:
1. A hearing aid comprising: a hearing aid shell with hearing aid electronics disposed therein, the hearing aid electronics including a power source, a microphone, a signal processor and a receiver, the receiver projecting a hearing aid amplified audio output out of a sound output port on a distal side of the hearing aid shell; and a flexible filament extending out of a proximal side of the hearing aid shell, the flexible filament extending outside the profile of the hearing aid shell, such that the filament interacts with a user's ear anatomy to determine an insertion depth of the hearing aid shell into the user's ear canal by preventing the hearing aid from being pushed too deep into the ear canal by the user, wherein the flexible filament attaches to the hearing aid at a first lower position and at a second higher position on the proximal side of the hearing aid shell, and wherein the flexible filament is in the shape of a ring including a cavum conchae portion and a cimba conchae portion, wherein the flexible filament attaches to the hearing aid shell with a top clip and a bottom clip, each of the top clip and bottom clip being removable from the hearing aid shell for changing of the flexible filament, the flexible filament being clipped differently to the hearing aid shell, at at least one of the top clip and the bottom clip, depending upon whether the flexible filament interacts with the user's right ear anatomy or with the user's left ear anatomy.
