Expanding on the 3M™ Scott™ Vision C5 Facepiece with E-Z Flo C5 Regulator, the facepiece now includes Bluetooth® communications to help address critical communication challenges on the fireground.  Utilizing proprietary noise suppression algorithms, in combination with a facepiece-integrated microphone, Bluetooth® enabled in-mask communications provide enhanced voice intelligibility during two-way radio communications. An optional integrated bone conduction headphone further assists firefighters with hearing and understanding of incoming radio communications.
