Yep genuine Shure SM57 and SM58 mics are the gold standard by which all others are measured. I have both and have used them for years with no ill effects. To say I am a fan of Shure SM mics would be an understatement. They are actually all I ever use. I have a box with probably half a dozen different brand mics that I have bought and tried out over the years and always go back to my shure SM series mics.
