The 3M Peltor Optime III Neckband Ear Defenders are a high-attenuation super-muff developed for extremely noisy environments. They suit you if you work around sustained loud noise and need protection across both high and low frequencies.
A double-casing design reduces resonance to give strong high-frequency attenuation, while speech and warning signals remain easy to understand. Broad, soft foam-filled sealing rings help the cups seal well with low contact pressure.
Key features

- Acoustic connection between the inner volume and the space between the casings maximises low-frequency attenuation
