Caldwell's standard e-max hearing protection combines great circuitry with a low profile earcup ideal for shotgun shooters and action shooters.The microphones in the e-max amplify sounds below 85 decibels, which includes 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.E-max hearing protection has a padded headband, audio input jack, volume control knob, and power indicator light.E-max earmuffs provide a 23nrr and run on 2 aaa batteries (not included).This model has a green finish on the earcups.
