This Active Audio / Da Cappo microphone really is as easy-to-conceal as they come, and due to it’s impressively small size, the microphone capsule is water resistant. Ultra small capsule only 2.5mm and these are rated at IP65 fully waterproof. The size of the mic mesh is smaller than a water molecule! These mics are ultra small and great for hiding in clothing or hair. They work well with Rycote Overcovers and Stickies and the LMC ISO Mounts.
