The Caldwell Low-Profile E-Max Electronic Earmuffs 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. The E-Max Low-Profile Earmuffs are now available in pink, to accomodate all the lady shooters out there.
