I did open the mic up at the bottom part where cable goes in no where for a battery in there . I will open up the other end have a look .
one of the amazon reviews says It does not have a 1.5 Vcc power supply as indicated, I will send it back and get a rode one thats takes a AA battery .
is this what I would need it takes a AA battery
