Caldwell 497700 E-Max Electronic Hearing Protection Standard

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)
