Security headset with microphone integrated in the PTT-button, excellently suitable for the MIDLAND HP 450-2 A, when an especially loud transmission is desired or other sound-tube headsets are too silent. The innovative circuit of the AE 31-2CL permits hands-free and transmission button mode without additional switchover at the microphone. Simply switchover at the radio set to VOX (hand-free function) or PTT (transmission-button mode). For radio sets with duo-socket: 2.5/3.5 mm
