An embodiment of a hearing assistance device comprises a housing, a power source, a radio circuit, an antenna and a transmission line. The radio circuit is within the housing and electrically connected to the power source. The antenna has an aperture, and the radio circuit is at least substantially within the aperture. The transmission line electrically connects to the antenna to the radio circuit. Various antenna embodiments include a flex circuit antenna.

Disclosed herein, among other things, are apparatus and methods to provide improved connections for components of hearing assistance devices. Various embodiments include an apparatus including a receiver case configured to house a hearing assistance device receiver, the receiver case including a spherical receiver spout having an opening. The apparatus also includes a receptacle housing having a spherical socket adapted to mate with the spherical receiver spout to form a ball and socket connection. An insert within the spherical socket is configured to establish a retained interference fit with the opening of the receiver spout when the connection is formed so as to create an acoustic seal therebetween.
