Vibes Hi-Fidelity Earplugs (seen on TV's Shark Tank) are discreet, reusable earplugs that FILTER SOUND by reducing the volume of loud environments to a safer and more comfortable level that prevents hearing damage, while STILL ALLOWING YOU TO HEAR EVERYTHING AROUND YOU CLEARLY. These earplugs, which come with three sizes in each box, are great for: concertgoers, musicians, loud group fitness classes, motorcycle riding, people with sound sensitivity, loud work environments, and more!
