Just get a cheep pair of buds from wal mart or a store of that such, you wont have to worry about them being lost/broken/stolen and you dont need some high tec quality audio headphones for skiing around.
... am on my 3rd pair after 2 seasons tho. stepped on one pair, and other pair just destroyed from eating shit on rails one too many times. maybe better off just getting some cheap earbuds.
trust me you want these. they stay in your ear PERFECTLY and the boosted bass gives them a really full frequency response. they are mad cheap and worth it, comparable to my ultimate ears and BLOW the skullcandy's i have had out of the water, even the $90 ones.
