Don't be fooled by the shiny mic grille that looks like it came straight off Elvis Presley's stage in the late '50s—the MV51 ($179.00 at Amazon) is a modern, versatile USB mic. (Though, for the record, many of those iconic mics Elvis sang into were, indeed, made by Shure.) Beneath the grille, the MV51 is a condenser mic utilizing a one-inch capsule in cardioid pattern.while its zero-latency headphone jack and onboard gain controls are inclusions in keeping with most of the similarly priced competition. For pure signal, there are other options in the price range that we favor slightly more, but as a versatile tool for podcasters and musicians, it's hard to beat the MV51's approach.
