To be honest, the first time I opened the package and saw how small and compact the ghost stryke II were, I had my doubts they would fully protect my hearing. But with their technology, memory foam ear buds, and a snug fit that doesn’t wiggle lose, proved my doubts to be wrong. My wife and I are both are blown away with the quality of the Ghost Stryke II. It’s so nice it has the capabilities of amplify hearing and completely dampen any loud noises. It’s clear that Sport Ear has taken hearing protection to a whole new level.
