smartPlugR IS: Intrinsically Safe In-Ear Solution Powered from Radio


The smartPlugR-IS (Intrinsically Safe version) is an in-ear hearing protection solution built specifically to enhance two-way radio communications in high-noise environments. The solution complements Sensear’s SM1R series, as it is powered by your two-way radio, thus eliminating the need for a battery inside the unit. Similar to the rest of Sensear’s portfolio, the smartPlugR-IS pairs Sensear’s patented technology and a noise-suppression microphone to allow users in high-noise environments to communicate either via face-to-face or via two-way radios while maintaining 360° audible awareness of their surroundings and protecting your hearing.

Some notable enhancements to the smartPlugR-IS include a larger more ergonomic PTT module for improved tactile button presses and a new detachable earpiece assembly allowing for multiple users to share the base unit on consecutive shifts.
