I've tried disposable ear plugs before and I could never get used to them. I couldn't get them in right, they kept falling out, they blocked out too much noise. My helmet is very quiet and so it ended up never being a priority. Pair that with my new wind screen from givi and my rides are relatively calm. I've noticed though, that after a 3 hour ride my ears are ringing. We are getting ready to goto Denver, and so I wanted something for my ear protection.
