24 decibel noise reduction

The K2M magnet earmuffs deliver a noise reduction rating of 24 decibels and can be used alongside the magnetic face shield on your Ceros® safety helmet.

Pressure-free fit

Outstanding comfort and a pressure-free fit are felt through use of lightweight materials, bringing together compact and memory foam cushioned earpieces.

360-degree nesting rotation

When not needed, earmuffs are able to twist and nest evenly across the top sides of the helmet, so you experience less strain and more balance.
