I may have small ear canals because I have a hard time finding earplugs that fit well and that do not get knocked out when I put my helmet on.
So I bought these in the hope they would fit, and they do! Impeccably.
The packaging is a little cheesy, but the earplugs themselves are perfect. Two different sizes of the black cones, ensure one of them will fit, and the removable sound damper (the red thing in the photo) means I can clean these easily, or move the little damper into another pair.
They fit well, and nothing sticks out to touch the helmet lining or interfere with the helmet at all. The little tab is easy to get a hold of, even with my fingers, to remove them.
The sound damping is perfect for riding. I can still hear everything I need to, but the wind noise is basically eliminated, and the overall sound level of everything is brought down to a comfortable level.
To test them out, I kept my helmet on when I went in and ordered my coffee in the coffee shop. I was able to carry on a normal conversation with the barista, even with these in, and my helmet on.
These really are the best earplugs I have ever had for riding. I recommend them highly.
