The Heil Sound HM-iC Handi Mic is a compact, lightweight handheld microphone designed exclusively for Icom transceivers.
Featuring Heil’s iC electret microphone element, the HM-iC delivers outstanding clarity, warmth, and articulation that perfectly complements Icom’s microphone input circuitry and bias voltage.

Unlike traditional microphones, which can sound muffled or hollow, the HM-iC’s precision-engineered iC element provides smooth, natural audio with excellent articulation, making your signal stand out on the air.
Its cardioid pickup pattern rejects background noise — ideal for use in busy shack or mobile environments.

Built to Heil’s broadcast-quality standards, the HM-iC combines professional-grade sound performance with the rugged reliability expected by serious amateur radio operators.
