SM1R / SM1R IS No Battery Noise Reduction Headsets

Headband style

Behind-the-Neck style

Helmet Mount style

The SM1R Series is built specifically to enhance two-way radio communication in high-noise environments. The headset is unique from the rest of Sensear’s portfolio in that it contains no battery and instead is 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-cancelling 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.

Here are just some of the many features and benefits that Sensear’s two way radio headset products have to offer.
