Does anyone know if there is a helmet that is wired for sound with pre installed headphones? Either bluetooth or wired is fine. I'd prefer to have something like that instead of earbuds.
Yes there is a break in period or should be, or its not snug enough. However it should not be soooo snug that it causes discomfort even on a long trip. If you do get into a situation though were you have a specific hot spot, try taking out your cheak pads and the pads on top of your head and look at the stiff foam. You should be able to use a spoon and press the foam in the spots that are causing discomfort and give you a bit more room for your head.
If I just bought a helmet, and it felt ok for an hour or so, I would take it on the trip.
