# The SP1R Series

---

![SP1R-datasheet](https://lp.sensear.com/hubfs/SP1R-datasheet.svg)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 and 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 SENS® technology and noise-suppression microphones 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 your surroundings and protecting your hearing.

The SP1R has the option of in-ear earplugs with an in-ear microphone (no boom mic.) or a lightweight heavy-duty headset with in-ear plugs and an external noise-canceling boom microphone. Additionally, the SP1R has an intrinsically safe option with UL and CSA certifications.
