"Know someone on the spectrum that's sensitive to sound? Vibes Hi-Fidelity Earplugs (as seen on ABC's Shark Tank) are reusable earplugs that lower the volume of your environment to a more comfortable level, but still allow you to hear everything around you clearly, instead of blocking and muffling sounds. Plus, Vibes come in three sizes in each package, and their clear design makes them much more discreet than earmuffs or bright foam earplugs.
