Just got my hands on some of these vampire and iso mounts for the Sanken cos 11 personal microphone. Having missed the vampire clip when I switched from Trams a while back they look dead handy and I am going to try them out over the next few weeks. They look very promising for a discreet placement of a mic, the trams always looked better in their vamp clip I thought,  and also possibly quicker than using double sided tape. There’s also a tapedown version with a furry wind shielded side which I hadn’t seen before and rubber iso mounts for placing in a tie knot etc.
