Sensear – smartPlug R / smartPlug R (IS)

Smart Noise Cancelling Ear Plugs

The smartPlug R is the perfect complement to Radios in High-Noise Environments. The smartPlug R 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 smartPlug R 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 smartPlug R include: a larger more ergonomic PTT module for improved tactile button presses and a new detachable ear piece assembly allowing for multiple users to share the base unit on consecutive shifts. Lastly, the smartPlug R is also available in an Intrinsically Safe version to for when equipment has to adhere to hazardous location standards.
