The shotwave earbud allows you to protect your hearing and listen to low db sounds in a small, comfortable silicone earbud system.These buds are unique due to their analog (non-electronic) proprietary design that allows the user control of sound protection through an external push button system.When you need maximum hearing protection-you push the selector button, and an audible/tactile click is heard/felt.When you need less protection (i.E., hear conversations)-you push the selector button again to switch settings.Color: Black/RedNrr: 12-25 dBStyle: In The EarMaterial: Silicone
