The new Sensear Intrinsically Safe Smart Muff is powered by SENS (Speech Enhancement, Noise Suppression) technology, which enhances speech and suppresses background noise so workers can hear speech and stay protected in high noise environments while remaining aware of their surroundings. The IS Smart Muff enables face-to-face, two-way radio, Bluetooth cell phone and short range communication capability all from the one device. Sensear Inc., Circle 254Sensear_300px.jpg
