The helmet itself gets 5 stars.. Its got awesome looks and I like looking like a BSG marine :) :) BSG used these exact same helmets to save cost and weight.
The audio gets 3 stars though.. for being very mediocre. They don't have a great soundstage and they sound better when you push the earflaps against your ears... but you wont be able to do this when you're riding down the mountain.
I wish GIRO teamed up with a different company than skullcandy to make their audio flaps.
