These are a pretty great product. There are lots of 'high fidelity' or 'concert plugs' but I think these are my favorite. The 2 flange is lower profile than the 3 flange and doesn't get pulled from your ear by your helmet as easily. They are a bit softer and more comfortable than competing products I have tried. The interchangeable filters is also a really impressive feature. You can sort of tune your plugs to do what you want. Noise wise they perform really well. I can hear cars near me and hear my intercom system easily, but the wind noise and engine droning is almost totally gone. I also use the same plugs for concerts and they do a great job of making the noise safer without making it muffled and unenjoyable. The case is really cool, the extra storage area for a backup 3rd plug is pretty unique and awesome, I have lost 1 plug on a motorcycle trip before which really sucks. Wish I had earpeace at the time. The case seals snug with the o rings, I carry it on my keychain daily and have no problems with it. I use baby wipes to clean the ear plugs after each use and they have not seemed to wear out or get torn up at all so far. Hope my review helps you decide if these are right for you.
