The Stilo Helmet and Radio/Intercom Communication Adaptor Lead is a black intercom system designed by Stilo. This system allows for seamless communication between the rider and their helmet, providing convenience and safety during rides. The adaptor lead is compatible with Nexus 4 Way radio communication systems.
I used to connect headsets and helmets to rally intercom system. It’s a male nexus type. I think it works with peltor, stilo, Zero Noise etc.
2 leads for driver and navigator
