Surefire Sonic Defenders feature innovative Earlock outer rings, which lock the earplugs in place using 7 grab-points. The low-profile design allows for easy wearing under a hat, helmet, mask, headset or supplemental muffs – even whilst using the phone. Filtered Sonic Defenders use established non-electronic technology to reduce dangerous noise whilst allowing conversations to be heard. Filter caps (included) can be inserted to block ambient sound and conversation. Dangerous noise is reduced to safer levels. The noise reduction rating with filter caps out is 11 decibels, with the noise reduction rating of 24 decibels when filter caps are closed. (Attenuation US. EPA Regulation 40 CFR Part 211, Subpart B ANSI STD S3 19-1974 - data available on request)
Includes hard plastic carry case with chain, earplug lanyard.
