This morning I went on my ride with my Cat Ear wind deflectors. I was very pleased with them. They are basically just a flat tube of soft material that mounts on the front straps of the helmet in front of your ears. They do not block out all wind noise but do block out a substantial amount. This greatly improves hearing traffic approaching from the rear, especially while pedaling in to a head wind. Yeah, they look a little weird (nothing outrageous), but so does a 60 year old male in cycling shorts and jersey. I would definitely recommend them for anyone who suffers from tinnitus as I do.
