Noisy environments can often be dirty too, and debris can get stuck to your earplugs, causing scratches and irritation in your ears. These Uvex Whisper reusable earplugs feature a smooth, dirt-repellent surface to help prevent a build-up of particles and they're easy to wash in soap and water at the end of the day. Designed for low-noise environments, they're connected to a cord which makes them convenient to wear around the neck when not in use and are supplied in a hygienic storage box to keep them clean between shifts.
