The Icom OPC-499 Headset Adapter Cable is a genuine Icom accessory designed to allow standard aviation headsets to be connected to compatible Icom handheld radios. By providing proper audio and microphone interfacing, the OPC-499 enables clear, hands-free communication when using portable transceivers in the cockpit.
This adapter cable is commonly used by pilots who prefer the comfort and noise attenuation of a full aviation headset rather than the radio’s built-in speaker and microphone. It is especially useful in noisy cockpit environments, during flight training, or when using a handheld radio as a backup communication solution.
Designed specifically for Icom aviation radios, the OPC-499 ensures correct audio levels and reliable microphone operation when used with standard general aviation headsets. As a genuine Icom product, it offers dependable compatibility and performance for everyday aviation use.
