A compact battery-operated speech projection device, MSA’s ESP II Communications System provides clear short-range communication for workers wearing full-facepiece respirators. Consisting of an encased microphone and speaker, the unit amplifies and aims the wearer’s voice to be heard even in areas with high levels of ambient noise. It is designed for use with MSA’s Millennium and Advantage 1000 Respirators.
