ISOtunes products with Aware Technology and ISOtunes Sport products with Tactical Sound Control are both great for handling loud impulse noises. Although they look and operate very similarly, the sounds and environments they are built to handle are very unique.
ISOtunes Sport products are intentionally built to protect firearm users from gunshot noise. ISOtunes products with Aware Technology are built to protect those who use tools and loud equipment from impulse noises (nail guns, hammers, etc.)
