Shure SM4 Review / Test

Today i review the Shure SM4, a new offering in the $200 price range. The mic is very straight forward with a cardioid polar pattern and no pads or switches. This is a brighter mic which controls the bass, has a neutral mid section, and then a dominant boost focused in the treble and air frequencies. I found that on some S's they could sound a bit sharp on this mic, and also the self noise is a bit high at 17dBA compared to the competition. The accessories are all nice and effective and the build quality is great.
