Abstract
An inflight headset includes a headband, a pair of shanks coupled to the ends of the headband, and a pair of earpieces adapted to be disposed over the ears of a user. A stub is provided on a lower end of each shank. A casing with an open end is formed on a housing which is adapted for receiving the earpiece. A cap is provided for enclosing the open end of the casing. The stub is rotatably and frictionally coupled to the casing when the cap encloses the open end of the casing so that the earpieces can be easily adjusted to different rotational directions.
