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.
