1. A head-mounted device (HMD) comprising:
a microphone;
an extra-aural speaker that is arranged to direct sound into an ambient environment in which the HMD is located;
a processor; and
memory having instructions stored therein which when executed by the processor causes the HMD while being worn by a user to:
capture in a microphone signal, using the microphone, user-desired audio content and ambient noise from within the ambient environment;
generate a user-desired audio signal from the microphone signal by reducing the ambient noise;
cause the extra-aural speaker to output the user-desired audio signal; and
transmit, over a wireless link, an audio signal that is different from the user-desired audio signal to a device that is being worn by the user.
