Standard profile E-Max hearing protection combines great circuitry with a standard earcup for more better protection. 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.

Specifications:

Decibel cutoff: 85dB
NRR: 25
Power source: two AAA batteries (not included)

The Caldwell E-Max electronic stereo ear muffs limit sounds above 85 dB by automatically shutting down the speakers when there is a loud noise situation. Enabled with one stereo microphone in each ear cup, the user is able to localize sound from all directions. The E-Max amplifies normal sound levels to enhance hearing when the earmuffs are being worn, yet will automatically shut down when noise levels exceed 85 dB. The comfortable, compact E-Max is a new low-profile design and operates on two AAA batteries (not included).
