Cardo guys. I know the Smart-H stuff is meant for use on certain HJC helmets right. Is it possible to MAKE it work with others? On a local online store the Packtalk Smart H is the equivalent of $125. The normal Packtalk Slim or Bold is more like $350. I'm thinking it might be worth it getting the Smart-H and "making a plan" on my Arai. Also, do any of the Cardos allow you to use your own earphones instead of the supplied speakers? The whole Mesh thing seems much better than Sena. I have an SMH5 and it never seems to work with anyone else.
