I have the E2 which is basically the C5 with a removable peak visor. I generally have the peak visor removed unless off road. I love the helmet but just wish the chin strap was about 2 clicks longer to be a little looser. The Sena is great for me but I have not been able to figure out how to use completely and join Cardos. I mainly use it for music and phone calls. Schubert has great customer support and when I scratched the visor on the 1st day of use, they sent me a replacement. That also reminds me that the visor will not stay open at highway speeds so you have to add some little o rings on the visor hinges for the visor to stay open at speed. Schuberth claimed this is a safety design for the visor to close but I don't believe that. I ride a lot with the visor up and the inner shield down. Anyway 2 O rings is like 15¢. They have options for colors, tints etc for both main and inner visors.
