The 3M Peltor Optime II H520B-408-GQ Neckband Ear Defenders provide reliable workplace hearing protection. The ear muffs effectively reduce noise levels by up to 31 decibels (SNR), protecting your employees when working in loud environments or with heavy machinery. For example, building and construction sites, airports, machine shops and more.
The Optime II ear muffs have sealing rings filled with a combination of liquid and foam. This creates an optimum seal with low contact pressure, providing comfort even during long term use. The large cups also reduce the build up of heat and moisture during extended use, and the soft wide cushions reduce pressure around the ears. This neckband model is designed to be compatible with other PPE and safety equipment. EN 352-1:2002 tested & certified.
