The 3M PELTOR Optime II H520B is the neckband version of this industrial earmuff. Its green cups provide room around the ears, while the wide, soft cushions distribute contact against the head. The rear band offers an alternative arrangement for workers whose other equipment makes an overhead band inconvenient.
Features and fit
- SNR 31 dB for the H520B neckband model.
- Spacious cups and soft, wide sealing cushions.
- Cushion sealing rings incorporate ventilation channels to support comfort.
- Rear neckband position keeps the main band behind the head.
- The appropriate 3M hygiene kit provides replacement cushions and foam inserts.
Select against the measured noise exposure and check fit with any helmet, face protection or eyewear required for the job. Position the band and cups exactly as instructed so the cushions surround both ears without gaps. Wear continuously during noise exposure, and inspect the seals before use. Regular cleaning and correct replacement of worn cushions help maintain the earmuffs in serviceable condition.
