Engineered specifically for the high-tier IC-A25 series airband transceivers, this compact 7.9-inch (200mm) conversion line allows pilots to connect standard twin-plug General Aviation (GA) headsets directly to their handheld emergency backup radio. The \u003cb data-path-to-node=\"4\" data-index-in-node=\"404\"\u003eIcom OPC2379 VHF (118-137MHz) Headset Adapter Cable\u003c\/b\u003e eliminates the need to rely on low-volume internal speakers or handheld microphones during flight operations, enabling clear, crisp intercom integration and loud reception through active noise-canceling flight headsets.\u003c\/p\u003e\n\u003cp\u003eBuilt to withstand rigorous flight conditions, the adapter interfaces with the radio chassis using a specialized right-angled, 2-pin slim L-type plug. The opposite termination breakout assembly splits into three robust, insulated input receptacles: a 5.23mm (PJ-068 equivalent) 3-conductor microphone socket, a 6.3mm (PJ-055 equivalent) 2-conductor headphone socket, and a specialized 3.5mm stereo socket. The auxiliary 3.5mm input is purpose-built to accept external yoke-mounted Push-to-Talk (PTT) trigger switches, providing flight crews with hands-free transmission convenience while navigating or controlling the aircraft.\u003c\/p\u003e\n\u003cp\u003eAviation technicians and flight safety coordinators should note that this product SKU consists \u003cb data-path-to-node=\"6\" data-index-in-node=\"95\"\u003estrictly of the standalone adapter cable block\u003c\/b\u003e.
