ABSTRACT:
A bone conduction personal audio listening device and method is worn behind one or both ears in substantially close contact with the mastoid bone of the listener. The device is maintained on the listener's ear by hooking over the top of the ear, by hooking under the bottom of the ear, and by the contact with the mastoid bone. Due to placement of the device behind the listener's ear(s) ambient sounds of the local environment can be heard. Provision is also made for the listener through ear plug means to block out ambient sounds if so desired. The listener can remove and replace the waterproof audio speaker assembly of the device for cleaning purposes, or to change the color or reflectivity of the device for safety and/or cosmetic reasons.
