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.
