Abstract
An insert earphone comprises a housing and at least one transducer that is located in the housing. The transducer is adapted to receive electrical energy and to responsively convert the electrical energy into acoustic energy for presentation to an eardrum of a user. The transducer is positioned within the housing so as to be in close proximity to the eardrum of the user when the housing is inserted into the ear canal. At least one sealing member is coupled to the housing. The at least one sealing member is adapted to provide an acoustic seal within the ear canal of the user.
