Shure's MV51 USB microphone looks retro but is loaded with modern capabilities. It is  a cardioid condenser mic that can record via USB to your computer or directly to an iOS device via the included Lightning cable. Beyond that, it's the only mic we've tested so far to offer both DSP (digital signal processing) and DSP-free modes. In fact, there are four DSP modes geared toward specific uses. That alone makes the MV51 a standout, 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.
