Shown is the HD 6XX in the product photos, but it isn't among the choices for purchase. The HD 6XX have oval-shaped ear pads and these are circular and obviously won't fit the Senns. Why would Drop try to trick their customers into buying something that won't work with their product? I've been looking for a Dekoni HD 6XX ear pad drop for a while, but these ain't it. I'm off to the Dekoni website.
