The SP1R-IS is a revolution in lightweight hearing protection. Built specifically to enhance two-way radio communications in high-noise explosive environments, it is powered by your two-way radio, thus eliminating the need for charging. The SP1R-IS delivers Sensear’s exceptional SENS® Technology into the most compact hearing solution in the industry. In addition to the lightweight, rugged boom microphone headset, the SP1R offers an in-ear microphone specifically for users of respirators or other equipment that restricts boom-mic usage.
