Sensear introduces its new IS Smart Muff, with one-of-a-kind SENS™ (speech enhancement, noise suppression) technology that enables users to communicate in high noise environments face-to-face or via two-way radio (with a compatible IS model), or Bluetooth through a cell phone without ever having to remove the hearing protection. Also enables muff-to-muff communication in short range distances. Sensear,www.sensear.com.
