All our filters are detachable and can be swapped through out filtered product range giving you a two in one product.

The Passive filter allows the user to maintain ambient awareness for example - Conversation, Hearing the Trap, Taking instruction and Fluttering of Wings whilst dampening high level impulse like gunshots. This gives the user all the benefit of ambient sounds they want to hear whilst knowing  they are safe from damaging sound.

*This is compatible with CF Auto, CF Dual, CF IND, CF Passive and CF Flip
