The Perfect Complement to Radios in Hazardous Locations
The SM1R-IS is built specifically to enhance two-way radio communication in explosive environments. The headset is unique from the rest of Sensear’s headset portfolio in that it contains no battery and is instead powered by the radio, making the unit lighter and more comfortable for the user.
Similar to the rest of Sensear’s portfolio, it pairs Sensear’s patented SENS® Technology and a noise-canceling boom mic to allow users in high-noise environments to communicate either via face-to-face or two-way radios while maintaining 360° audible awareness of their surroundings and protecting their hearing.
Sensear's two-way radio headset products, including the SM1R-IS Series, offer unmatched reliability, performance, and comfort for professionals operating in demanding industrial settings. Discover the unparalleled advantages these cutting-edge solutions can bring to your workplace.
