With an NRR of 30 dB and a 1.5 millisecond response time, the Pro Ears Electronic Ear Muff provide excellent protection against loud noises, especially the kind you hear in shooting ranges.
The over-the-ear cups and headband both are made from 100 % memory foam to provide unprecedented comfort for those long gaming sessions (which is a step up from its predecessor which only had memory foam earmuffs).
