Over-the-head earmuffs are the most common form and are worn when hard hats and faceshields are not required.

Active noise-suppressing over-the-head earmuffs have integrated electronics that amplify speech to allow workers to communicate and compress ambient and impulse sound to a consistent level. Active suppression can be turned off so earmuffs block sound passively. Over-the-head earmuffs are the most common form and are worn when hard hats and faceshields are not required.

Hard hat-mounted earmuffs attach to slots or adapters on a compatible hard hat. They make it easier for workers to wear hearing protection without having to manage a separate piece of equipment. Final NRR rating achieved is affected by fit and the hard hat to which the earmuffs are attached.

PAPR (powered air-purifying respirator) system earmuffs attach to compatible PAPR headgear to ensure a good fit. They also make it easier for workers to wear hearing protection without having to manage a separate piece of equipment. 

Pad kits replace worn or lost ear pad cups to extend earmuff life span and restore performance. They also supply clean pads for a new user. New pads optimize hearing protection by maintaining a seal around the ears.
