Advanced Protection for Harsh Environments: Dielectric Safety with Helmet Attachment

The 3M™ PELTOR™ Optime™ II Earmuffs H520P3E-410-GQ-01 are designed to provide high-level hearing protection ( 31 dB ), responding effectively even at the lowest frequencies. Featuring a dielectric design for electrical isolation, these high-visibility green earmuffs clip directly onto the helmet, ensuring stability and extreme comfort thanks to the liquid- and foam-filled sealing rings. They are the ideal solution for those who work in harsh industrial environments or on high-risk construction sites, where hearing protection must integrate seamlessly with other safety devices.
