Unbranded M and P Sigma Electronic 20 NRR Hearing Protection with Sound Amplification and Adjustable Earmuffs

The Smith & Wesson Sigma Electronic Earmuffs combine great circuitry with a low-profile ear cup that is ideal for shotgun shooters and action shooters. The 2 microphones in the muffs amplify sounds below 85 decibels, which amplifies normal communication, range commands and environmental sounds. Above 85 decibels, the microphones shut off to protect the shooter's hearing. Enabled with 1 stereo microphone in each cup, the user can localize sound from all directions.
