Special cable for Heil iC electret headsets 3.5mm jack to 8p8c modular RJ45 for Kenwood

Thousands of cables sold worldwide!



Heil headsets with the 'iC' electret (condenser) element specially produced to work with Icom transceivers need DC voltage on the microphone pin to work. As a result, they cannot normally be used with other brands of radio.

In response to customer requests, we have designed this special adapter so you can now use your Heil 'iC' headset with your Kenwood transceiver.

Sturdily made using high quality components, this cable connects your Heil iC headset or HMM-iC hand microphone to your Kenwood transceiver (with 8 pin modular RJ45 microphone connector).


  • 3.5mm jack socket for 'iC' microphone
  • 1/4" (6.35mm) jack socket for optional PTT input
