Heil AD-1-KM Headset Adapter For Kenwood Modular.
Heil Sound Headset Adapter Cables are used to interface your Heil headset to your favorite transceiver. AD-1 series cables are required for Heil boom microphone headset models. All Heil Headset Adapter Cables use commercial-grade microphone connectors with dual-exit cable clamp. If you have several brands of transceivers, individual adapter cables may be connected to each radio, so you may quickly and easily move your Heil boom microphone headset from one transceiver to another.

The Kenwood adapter made switching from my Icom HF radio back and forth to the Kenwood easy and quick. The Heil line never fails. The adapter system makes it very easy to go between different radios with the same headset for various operations while continuing the outstanding quality of sound. Greatest idea I have used in hear technology in amateur radio.
