Headsets with 3.5 mm mini-jack

3.5 mm (mini-jack)

— standard plug 3.5 mm (mini-jack). Usually plays a supporting role and is intended to be connected with another speakerphone (or speakerphones) into a single system; as the main connection method, USB is most often provided, less often Bluetooth.

Note that this connector should not be confused with the headphone jack (see "Features") — these are two different functions that do not depend on each other.
