A phone jack for a 5.1 channel headphone adapted to a 5.1 channel phone plug having a plurality of upper grooves arranged one after another on a top of a main body and at least six conductive pieces fitted into the upper grooves to establish a pressure contact with the electric terminals of the inserted phone plug. The 5.1 channel phone jack has an easy assembly and establishes a stable electric continuity with the phone plug, thereby resulting in an excellent transmission of 5.1 channel audio signals.
