The Headsets and all accessories are provided in a personal pouch for easy storage.
The Auralite Executive Headset (Headset No. 3A) is the same as the Auralite Headset but
a quick release plug incorporated in the cord which gives the user greater mobility as the
Headset can be disconnected without losing a call in progress.
