I bought these after losing my previous set of earplugs, Surefire EP4s. Wearing the Race model under a Bell Star DLX (not the race star) on a CBR600. Turns out this helmet is made for more of a touring than sport riding position according to Bell so the wind noise is a bit louder.First off these are the most comfortable earplugs I have ever worn and the first set that have stayed in place for more than an hour or hour and a half. Cheap foam plugs seem to work their way out of my ears after 30 minutes, and the EP4s would last maybe an hour and a half before they were starting to work their way out. Also the EP4s would press on my ears just enough that they were getting a bit sore by that time anyways. I wore these for a 3-1/2 hour round trip this weekend and they stayed snug in my ears the entire time, and are comfortable enough that I could pretty much forget they were there at all. So, I absolutely love the comfort on these and if I ever lose them I'll buy another pair on that fact alone.Also great is they filter just the right amount of noise for riding. Foams and even Surefires with the caps open filter a lot of noise out, great for protection but more than needed in my opinion. My helmet is quite loud at highway speeds, and these still cut out almost all of the wind noise but when I pull up to a light or just stop to talk I can still hear people well enough to talk. I couldn't really do that with the EP4s or especially foams.I haven't tried every earplug available, but these are definitely my new favorite and I don't believe I need to try anything else now. The little insertion tool is a nice addition too, makes getting them in super quick and easy.
