Connect Your Headset. Keep Your Seal. Fly with Confidence.
The Wirenest Aviation Headset Adapter Cable connects any standard GA dual-plug headset to your Icom handheld transceiver. Designed as a high-quality aftermarket replacement for Icom OPC-2379 and OPC-499, it adds a convenient 3.5 mm jack for an external push-to-talk (PTT) button — while maintaining the weather-resistant integrity of your radio.
A precision-fit rubber gasket surrounds the molded L-type 2-pin connector, helping to preserve the IP57 water-resistance rating of the Icom IC-A25 series. Whether you're training, traveling, or flying in humid conditions, your radio's port remains protected.
Compatible with Icom IC-A3, IC-A6, IC-A14, IC-A22, IC-A24, and IC-A25 (A25C / A25N), this adapter ensures clear transmit and receive audio with full side-tone feedback.
