GSP-15 are active hearing protection/enhancement devices (HPEDs). HPEDs use electronic circuitry to restore the situational awareness that is generally lost when the ear canal is obstructed. GunSport PROs provide the hearing protection you need while not compromising sound detection, localization, and clarity. What is adaptive attenuation? Think of’adaptive’ as being able to change with the environment. GunSport PRO earplugs contain circuitry that automatically adapt as sound levels change. When sound levels are safe, hearing is natural, as if nothing is in the ears. As the sound pressure level (SPL) increases, the circuitry gradually adjusts to protect from loud noises. Technology Inside GSP15 electronic earplugs use high-definition balanced-armature sound drivers, high-sensitivity microphones and specially developed signal processing.
