As New.-----------------------------The Sennheiser ME 66 is a short shotgun microphone capsule designed for use with the K6 and K6P powering modules: It is especially suitable for reporting, film and broadcast location applications and for picking up quiet signals in noisy or acoustically live environments as it discriminates against sound not emanating from the main pick-up direction. Matt black, anodised, scratch-resistant finish. A widely used, broadcast industry standard short shotgun mic,  Super-cardioid/ lobar pick-up pattern, Highly directional,  Low inherent self-noise,  High sensitivity, Wide frequency response.  XLR K6 powered capsule.   If you are shooting solo this is the shotgun mic to use, it's not too directional to be used hand held or camera mounted (a longer shotgun mic really needs a sound engineer to avoid shooting past your subject and recording background ambient sound).
