Caldwell 487557 E-Max Electronic Low Profile 23 dB Over the Head Green Ear Cups with Black Headband & Adjustable Volume Control for Adults

Combines great circuitry with a low profile earcup that's ideal for shotgun shooters & action shooters. Two microphones amplify sounds below 85 decibles. Above 85 decibles, the microphones shut off for a split second to protect the shooter's hearing. Two microphones (one in each earcup) give the user true stereo sound and allow the user to identify the directional source of a sound.
