The bottom portion includes a speaker device mounted at a proximal side thereof and being configured to frictionally fit at the diverging ear opening in close proximity to the skull, with the upper half resting against the ear or being in frictional contact with an upper lip of the ear extending from the top cartilage. The device includes a printed circuit board contained within the casement, a battery compartment, on/off power and volume switches and a tuning circuit for providing selection of desired frequency. The total structure is housed within the casement and weighs less than 2.5 ounces.
