Summary: This is the same mic as the Apex 880 which I have reviewed under its own title. A Chinese manufacturer produces these mics under several names. They lack an isolation ring around the mic capsule, so they are noisy to handle and will pick up every bump and thump. They are solidly made and the mic capsule is one piece molded so it's pole and magnet are always aligned for optimum performance. That said, they also sound fabulous with a little high end boost.
Summary: I purchased an SP-5 on sale around a year ago. I was so impressed with it, I purchased four more. What initially piqued my interest, was the neodymium cartridge, and a low impedence of 250 ohms. This is one of those rare exceptions where "you get what you pay for" does not apply. I compared the SP-5 to a number of microphones...
Summary: Nothing special about this microphone. It actually doesn't sound horrible, but doesn't sound good either. Of course, it is a very inexpensive dynamic mic. I really wouldn't bother with this one. Other inexpensive dynamics,such as the the EV CO5, or the Shure PG-58, are better.
Summary: When I bought my Kenwood TS-450S on eBay, I was disappointed when it arrive sans a microphone (it was pictured with a hand mike attached). Oh well, I had a couple of mikes I could try. To make the long story short, neither one was really satisfactory. So, I went back to eBay to find a mike. I really wanted a desk mike but didn't like the prices I was seeing for Kenwood mikes ($60.00and up!). I broadend my search to all mikes rather than just communications mikes.
