Caldwell Electronic Ear Muffs
The Caldwell Sound-Right Es-85 electronic stereo ear muffs limit sounds above 85dB 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 Es-85s amplify 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 Es-85s run on two AA batteries (not included).
