Hi, i imported these made in USA, Dynamic Stereo Microphones (that you wear on your head like headphones) a few years ago. They are especially good for recording loud or bassy R&Roll or Rockabilly music. They will plug in to most camcorders or SLR cameras where you want to use external microphones. You may have seen me at various gigs. The quality of these mics are excellent and really capture the "surround" live feel due to the same proximity of your ears, and of course can handle HEAPS of volume. The pre amp(size of matchbox) with bass filter cut, and the case come with it. They have not been used excessively due to me using various microphones for different occasions. Cost me well over $1000 and am selling for $600 due to financial reasons. If your into recording concerts these are the ones to get (and so discreet).
