EarPro EP-3 Sonic Defenders®- EP3 from SureFire
I have several sets that I use when ridding, shooting, woodworking, so on, and so on. They really work as well as they say. On the bike I can hear the sweet music playing from my four piston orchestra while drowning out the majority of annoying wind noise. When shooting I can carry on a conversation with the people around me, and still cancel out the muzzle blast.
