I wear a pair of sony ear buds. I picked up on sale for like 20 bucks. I like them bc they have several rubber earbuds you can chabge to fit your ear size. I also chose buds bc I wear a helmet. I also wear an under armour head facemask thing which helps hold them in my ears. Hope that helped
For those audiophiles out there look for some of the upper end senheiser earbuds or JVC, I just bought a pair of AKG K701 reference headphones I wish I could take on the slopes with me but I don't want to risk breaking em.
If you are looking for passive noise reduction, I have had great success with Comply NR-10 earbuds (more like ear plugs). They are excellent for cancelling out wind. I actually wear them instead of my Bose QC15s. They are only 40 bucks doing a search. Don't bother with the NR-10i, too much money for not a lot more. I've used them to 55mph on a motorcycle and still enjoyed it.
