The 3M Peltor Optime II H520P3E-410-GQ Helmet Mounted Ear Defenders provides high level hearing protection that combines well with other PPE. They effectively reduce noise levels by up to 30 decibels (SNR). Optime II is a suitable choice for environments with substantial industrial noise or construction machinery, airports and agricultural work. For example, agriculture, building and construction sites, airports, machine shops and more. These ear muffs have a P3E attachment, for use with MSA safety helmets.
The Optime II ear muffs have a classic green colour with large cups, which reduce the build up of heat and moisture during use. The soft wide cushions also reduce pressure around the wearer's ears for improved comfort. Tough, hard wearing and easy to care for.
