A two-way voice communication device which provides a high-level of
acoustic noise reduction is disclosed. A resilient ear tip provides
acoustic isolation and secures the earphone within the ear canal of the
user. The ability to rotate the earphone within the ear canal allows the
user to easily position an attached microphone. The audio signals may be
conveyed by an included radio frequency receiver and radio frequency
transmitter, or the earphone may be connected to an electrical audio
device using a multi-conductor cable. Audio signals may be conveyed to
one or both ears of a user. A switch to mute the audio signal from the
microphone, or for supporting a push-to-talk mode of operation, may be
included in the earphone housing, or on the cable.
