I was recently looking for an inexpensive quality mic primarily for voice recording. I also wanted something very portable. I was familiar with Sound Pros from my purchase of a minidisc recorder several years ago. Since then they came out with an even less expensive version of their basic binaural mic. I heard the musical sound sample on the website and was very impressed, given that it was recorded so inexpensively. I also knew of Core Sound but their low cost binaurals were more than the Sound Pros and I doubted that they would be any more suitable for my purpose.
I called Sound Pros and got Chris on the line. In a manner of minutes, he quickly explained the handful of mics that would suit my purpose, why I would want omni over cardioid, and then was able to focus me on to one particular mic. I got the mic two days later, an SP-BMC-2, which is the least expensive binaural they sell and the one recommended by Chris. Recording quality going directly to minidisc without a battery box was very good. In fact, it was a bit too good, picking up a lot of ambient noise that normally is filtered out by the human ear. When I called back to ask if this sensitivity issue could be addressed, another salesperson spent about half an hour with me explaining other options. As it turns out, I found a way to reduced the ambient noise significantly in Audacity and I will keep these mics. For the quality of the mics for the price, as well as for their customer service, I recommend them.
Personally, customer service is important and I do expect a high level especially if I am dealing with an owner. As far as I am concerned, as good as a product may be, there are too many other good products out there to have to accept lacking customer service.
