Caldwell® E-Max™ Low Profile Electronic Hearing Muff

The low-profile E-Max™ Electronic Hearing Muff combines great circuitry with a low-profile earcup that's ideal for shotgun shooters and action shooters. The two microphones in the E-Max™ amplify sounds below 85 decibels, which amplifies normal communication, range commands, and environmental sounds. Above 85 decibels, the microphones shut off for a split second to protect the shooter's hearing. Two microphones - one in each cup - give the user true stereo sound and allow the user to identify the directional source of a sound. Requires 2 AAA batteries (sold separately).
