The CF Auto is a custom ear plug specifically designed and cut very flush to go underneath a helmet. It is made of a 25 Shore soft silicone ear canal tip going into the inner ear and a 40 Shore outer shell to give ultimate comfort whilst being worn underneath a helmet.

The Auto filter allows the user to maintain ambient awareness for example - Traffic, Emergency Services, Internal Helmet Speakers and some Engine Noise whilst dampening high frequencies like wind noise. This gives the rider an amazing experience allowing them to still enjoy the sound of their motorcycle and feel safe whilst doing so.

It is one of our top selling custom ear plugs from the whole range and well reviewed all over the motorcycling sector.
