Otto Engineering NoizeBarrier Micro Reviews
Worth The Investment!

I Utilized The Earplugs This Weekend At A Sporting Clays Shoot. They Functioned Perfectly But Not As Comfortable As I Thought They Would Be. The Foam Eartips Are More Comfortable That The Rubber Tips. If I Had It All Over To Do Again, I Would Purchase Them Again!!
Worth the price!

After a few sessions at an outdoor range, I can say I would recommend this product to anyone that is seeking comfort and functionality. I paired them with Comply foam tips and I couldn’t be happier. I wish I made the investment earlier!
