The 'EP4 Sonic Defenders Plus' Shooters Ear Plugs Hearing Protection by Surefire will protect your hearing at the shooting range. You will however, be able to hear routine sounds, conversation, and the range master commands.
EP4 Sonic Defenders Plus are triple-flanged shooters ear plugs for those with larger ear canals.
Safe sound levels are allowed to pass through while potentially harmful noises (above 80 db) are reduced via a proprietary design that incorporates the patented Hocks Noise Braker filter.
If you do not need to hear conversations or routine sounds, and if you need even more hearing protection, the Sonic Defenders' attached stoppers can be inserted into your ears.
