3M 540 A Optime III Headphone

Headband option. The 3M Peltor Optime III headset is a high-performance hearing protector and was developed for extremely noisy environments. The shielding feature is based on a dual-hull technology that minimizes resonance and provides maximum high-frequency isolation. The acoustic coupling between the internal sound and the sound between the bodies provides maximum low-frequency isolation. Closing rings are wide and filled with soft plastic foam for best fit and low contact pressure. The 3M Peltor Optime III headset means effective protection and highest comfort for users. Also available is an electrically impermeable model with no visible metal parts and a Hi-Viz green model for workers who need to wear hearing protection and need high visibility when working in road construction, airports or other high-risk areas. Headsets can be mounted on the helmet. Hygiene kit available
