I want to get some binaural mics from Sound Proffesionals to use with my Zoom H2. What are some good binaurals mics from them? I can't spend over $100. I was gonna get some low cost mics from Core Sound, but they won't answer and I need mics by tomorrow.
To answer your original question (as another poster down here alluded to), I think SP makes good products, Church makes good products, and Coresound makes good products. However (making a big assumption here) if your goal is recording loud rock concerts, I am not sure $100 will get you something usable from any of these three manufacturers (and thus, why you might want to buy a set used). Recording loud shows requires that you run mics + power supply, and generally, mics that have been modified to handle high sound pressure levels. I don't believe the Coresound "low cost" mics do this, and nor do the Sound Professionals ones (though you can pay a little extra for their mod).
When I first started taping I thought I'd save a little money and bought some non-powered mics and tried running them. I was (as I admittedly had been told) constantly disappointed when my shows came out distorted. Better off saving a little cash and getting the right mics the first time.
Any of the normal "small mic" options (SP, Church, Core, Sonic Studios) WITH a power supply (aka "Battery box") will do what you need. It's a good idea to ask questions of the folks who make them before you buy, also. If you give a clear indication of what you want to use them for and roughly what your budget it, the manufacturer will steer you in the right direction.
