The Full Metal Jacket (FMJ) is a great music solution for snowboarders who want an earbud headphone with the full sound of a pair of quality over-ear headphones.

Skullcandy's FMJ headphones are a styley, lightweight, and great sounding option for on-mountain tunes. You get full, rich sound in a sick metal shell. 

The buds come with three different sizes of silicon grommets, so you can be sure that they'll fit in your ear comfortabley. They form a comfortable seal betweeen the headphone and your ear, which helps block outside noise; so well, I recommend riding with only one of them in your ear, so that you don't block out the sounds of other people on the mountain. 

They're a little pricey, but you're not going to find a pair of ear-bud headphones with this kind of sound quality for any less.
