XP Reactor offers you one of the most innovative sound filtering solutions yet. You’ll hear sound clearly and naturally- almost seems as if your ears aren’t even plugged. Then when loud sounds hit your ears, the Dynamic Mesh Filtering System™ will automatically screen those sounds out protecting your hearing. You’ll get 33 dB SNR against loud impulse sounds while still maintaining normal hearing. You’ll also have 5 dB SNR hearing protection against general sounds.
