When activating sneak mode, a soft mechanical whirring similar to a camera lens can be heard as sneak sight takes effect. It is not necessary to be wearing the matching sets of armor in order to receive the sneak sight effect from the helmets. Sneak Sight is an effect granted by wearing either the riot gear helmet, or its superior versions: the advanced riot gear helmet, or the elite riot gear helmet.
