| 1. A two-way voice communication device comprising:
a receiver for transducing a first electrical signal into sound;
an ear tip for insertion into an ear canal of a user, wherein the ear tip is rotatable in the ear canal of the user, the ear
tip, upon insertion into the ear canal, uses the ear canal to provide support of the device, thereby securing the device in
an operable position on the head of the user without requiring use of additional attachment to the user, the ear tip providing
a reduction of external acoustic noise of at least 7 dB; and
a microphone for transducing speech of the user into a second electrical signal, wherein the microphone is positionable relative
to the mouth of the user by rotating the ear tip in the ear canal of the user.
