Designed for shotgun and action shooters, Caldwell's low-profile pink E-Max hearing protection enhances your range experience. It amplifies safe sounds below 85 dB, such as commands and conversation, while quickly blocking harmful noise above that threshold. With stereo microphones, you can easily pinpoint sound direction. These earmuffs offer a 23 NRR, a comfortable fit with an adjustable, padded headband, a volume knob, and fold down for easy storage. Requires 2 AAA batteries (not included).
