SP1R: In-Ear Solution Powered by Radio


The SP1R is a completely redesigned in-ear hearing protection and communication solution in a small and compact yet rugged package. Built specifically to enhance two-way radio communications in high-noise environments, 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 SP1R pairs Sensear’s patented technology and noise suppression microphones to allow users in high-noise environments to communicate.

The SP1R has the option of earpieces with an in-ear microphone or earpieces supported by a lightweight headset with an external boom microphone. Additionally, the SP1R has an intrinsically safe option, the SP1R-IS, with TIA, CSA, & UL certifications.
