Calmer ® Extra is an ear plug alternative that reduces stress from noise whilst allowing you to control the volume. Unlike regular earplugs that muffle sound, Calmer Extra are hollow which means you still hear everything clearly. This version comes with extra push-in filters so you can control the volume. You can select between no volume reduction (without filter) or -10dB (with filter). Wear Calmer Extra in your ears whenever you are in a noisy place to reduce stress and feel more relaxed. You still hear everything clearly, which means most people forget they are wearing them. Calmer are life-changing for millions of people who are noise sensitive but the technology benefits everyone. Wear Calmer Extra in any noisy environment and you won't believe how calm and relaxed you feel all day/night long.
