New electronic safety headphones from Würth eliminate noises over 85db, while amplifying low level sound to allow normal conversation in a noisy environment. Featuring a built-in microphone and Off/On switch with volume control, these comfortable headphones counter prolonged exposure to loud noise that can lead to serious hearing problems. The headphones are powered by 2 AA batteries (not included) and meet ANSI specifications. See us at AWFS- Booth #2114.
