If I may interject a thought here...I'm sure you guys know how to properly install a helmet headset but the problem I see with that is knowing how deep to set the speakers. Those of us who have done this job many times know how tricky that can be. Even good helmet speakers don't have good fidelity unless they are placed really close to your ears and probably even touching the ears. Of course, if they're placed too close, they can irritate your ears. I have found this part of the installation to be trial-and-error to get them right .
