Abstract
A hearing aid includes a relatively rigid shell which holds hearing aid electronics and one or more flexible, shape-retaining filaments attached to the hearing aid shell. The filament(s) extend(s) out a proximal side of the hearing aid shell having a shape which interacts with the user's ear anatomy such as the conchae bowl. The shape determines an insertion depth of the hearing aid shell into the user's ear canal, and a spring action biases the hearing aid toward the desired insertion depth. The hearing aid supported by the filament(s) provides an open, unoccluding position in the ear canal.
