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.
