I was looking at the instructions for my headset that came with my bike for the intercom and CB, it is set up for open and full face helmets but I normally ride with a half helmets, is there a replacement or mod that works with a half helmet?

 

J&M makes a headset for half helmets. My friend has one.

 

KBC makes a half helmet with speaker pouches in the ear curtains. I use the HD headset in that helmet.
