I've got a pair of AKG 451s and they're great for music but they're pretty prone to pop and blasting from voices in close. I need to use one on a singer shortly for visual reasons really - extension tube and it looks great - BUT this singer I know is a bit prone to moving in a bit close. What I'm looking for is some kind of windshield but it must be small and visually invisible (or close) a bit of foam that doesn't jump out might do? Has anyone seen anything suitable?
