the choices for earbuds are fairly limited. for $10 to $20 dollars you can pick up earbuds from most major manufacturers and they'll pretty much all sound the same. plus they'll probably fall out all the time when you're skiing. in-ear ones would probably be better since they're stuck in your ear and won't fall out easily and they have superior sound quality. the cheapest, good quality in-ear buds are the sony mdr-ex51s and 71s. if you're looking for ones targeted towards audiophiles, then look into etymotics, shures, or ultimate ears. those ones are generally over $100.
