The Original

Designed for shooting, this custom ear plug incorporates a passive filter encased in a protective housing.

This new age fitler gives extra clarity in sound whilst maintaining its quick impulse protection.



Simple in Design

The wearer gets the opportunity to carry on a normal conversation with a slight reduction of volume, whilst the unique filtering technology will protect you from any sudden high level sound. This custom ear plug is designed for easy use. Push in and you're ready to go.

Impulse Filter 

The CF Passive is a single setting product including an impulse filter incorporated within our own designed and manufactured metal housing for great protection of the filter itself and for a great look.

Product Overview

The CF Passive is great for ease of use. The filter is simple in effect of allowing low level sound to come through but high impulse sound (gunshots) to be blocked. 

It is highly recommended as a product that is simplistic in design with high end results.



"In a word brilliant, so comfortable and great fitting.  I have actually driven home from the range on one occasion before realising they were still in my ears!  I love how you can hold a conversation yet have the reassurance that you are protected from any damaging noise." - Ryan

"Excellent products, at a great price with fantastic service" Tom Sykes, Sporting Gun Magazine.


Just a quick line to say thanks for the ear plugs, I have used them a few times now and find them very effective and very, very comfortable, comfort was a worry i had after the fitting found i had “funny” shaped ear canals.

I will be recommending your company to all my friends and colleagues who have a requirement for such equipment." - Mark
