E-Max Hearing Protection combines great circuitry with a low-profile earcup that's ideal for shotgun and action shooters. The two microphones in the E-Max amplify sounds below 85 decibels, which helps you hear 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 them to identify the directional source of a sound. Includes an integrated audio input jack for playing music.
