I read on-line that the 3M (EAR soft grippers) were the best earplugs for cutting noise and for best comfort under a helmet. (webbikeworld.com) So I picked them up and wow, what a difference. Here's why .. Not a big fan of highly reusable earplugs for the simple fact that it can introduce nasty diseases if not steadily cleaned. The little squishy plugs found at a hardware store was what I was using but often they did not fit because they were not squishy enough or just did not insert correctly and then one ear would be quieter than the other or one would get knocked while putting on the helmet. Still I would use a pair for a day and then throw them away. Well all of the above is gone with the 3M product. They fit - end of story and they cut the noise significantly while still hearing what is going on around you. They really are good. WBW did say they liked this plug much better before they connected them with a plastic string (which is all you can buy). But, the string is easily cut. I am impressed with these so I would just pass along my experience.

Thanks for that. Uline.com recommends those "for larger ear canals", and have a noise reduction rating (NRR) of 31 db. Maybe I'll give them a try. But they are a fair amount more expensive than most I've tried.
I don't much care for the little attached string either. I'll cut it off, but I do leave about an inch attached. Some plugs will go in a little deeper than others. Leaving a little bit attached allows me to cram them in a little deeper without turning it into a chore to pop them out.
I'm a man, and I can change, if I have to, I guess.
