A headset gooseneck refers to the flexible portion of a headset that allows the user to adjust the position of the microphone boom or the earpiece to their desired angle or position. The gooseneck is typically made of a flexible metal or plastic material that can be bent and adjusted to fit the user's head and ears comfortably. This feature is particularly useful for individuals who need to use headsets for long periods of time or those who need to adjust their headset frequently for different tasks.
