Would probably list this down with other products I want to try out. Thanks!I wear Etymotic High-Def Motorsport Earplugs. They fit really well under the helmet. Wind and motorcycle noise don't go away completely, but they are knocked down by a few decibels. I can still hear music, phone calls, or GPS directions through my Sena.
They fit well, but after a 12 hour day it feels good to take them out. There is a string that you can tie on to ensure they are together, which is nice. The string can get snagged and tug them out slightly. That can get annoying. I usually make sure I do a test look from side to side before I start my ride.
I recommend them.
I would link them to Amazon but my post count is too low. Amazon has them for 23.
