Quite new to all of this I am too, and very surprised at the quality of recordings from a pair of binaural mics as tiny and cheap as the ones I made with two 0,60 USD capsules simply soldered to 1USD earphones. That hardly needs knowledge of soldering, and if you take capsules for 1,50 each and better cables, OK, don't spend 3 USD but 5.
I'd love to have real good mics, but if it is just entry level mics, why spend 50 or 100 USD if I can get the same quality for just 3 or 5 USD!
