I dont like to have ear flaps on my helmets. I just use the little earbuds and they stay in nicely cause I where a baclava. Just seems like you'll be paying a lot more when you could just use regular headphones
It's a sweet helmet, a little too big for me though (looks wise, it looks like I'm wearing a space helmet). If Smith fits your head, check out the Smith Maze, it's lower profile and waaaay lighter. It's a bit more delicate, but like almost all helmets, it's only rated for a "single impact".
