The Tonedown® E100 electronic earmuff from Sellstrom provides excellent hearing protection while allowing the wearer to carry on a conversation or hear warning calls, automatically silencing all noises above 85 dB. The muffs are ideal for wearing while operating pneumatic air tools, power tools, table saws, chainsaws and routers, and in other noisy environments.
