X30i Earplugs offers you one of the most innovative ear plug solutions yet. Simply choose which tip works best for you, insert these ear plugs in your ears, and then decide which mode you want to be in: Open or Closed. In Open Mode, you'll hear sound clearly and naturally, then when loud sounds hit your ears, the Dynamic Mesh Filtering System will automatically compress those sounds to protect your hearing. In Closed mode, simply close the valve for total hearing protection from all sounds. These are small, handy and can go anywhere with you, so you always have hearing protection when you need it without blocking off all your hearing.
