3M PELTOR OPTIME III BLACK/RED

3M PELTOR OPTIME III BLACK/RED PASSIVE HEARING PROTECTION - Product Description
3M™ Peltor™ Optime III is the best choice for extreme noise exposure. This hearing protector is based on a new technology: double shells minimize resonance in the capsule. This achieves maximum high-frequency attenuation, while signals and speech can still be easily perceived. The acoustic connection between the interior and the space between the shells ensures optimal attenuation of low frequencies. The wide, soft foam-filled sealing rings guarantee a good fit and low pressure. 3M™ Peltor™ Optime III is characterized by high insulation performance and best comfort.
