The 3M Peltor Optime II Headband Earmuffs are over-the-head hearing protection for loud work, reducing noise levels up to 32 dB. The H520A was built for demanding noise-hazard environments, so it suits crews working near construction machinery, airport aprons, agricultural gear and general manufacturing plant. Rated 32dB SLC80.
Wide, soft cushions spread the pressure around the ears instead of pinching, which matters when the muffs stay on all shift. The cups have plenty of room inside, helping cut down heat and moisture build-up in Perth summers. Cushions and inserts are available as replacement Hygiene Kits, so a well used set can be freshened up rather than binned. A solid pick for mining, transport and heavy infrastructure work.
