We found the Speech mode to be a slightly stronger signal, and the Singing mode to sound a tad more compressed. That said, the compression in this mode isn't overwhelming—sure, you can make things sound heavily processed by pushing the gain high and speaking close to the mic, but we don't advise it. With judicious mic placement and thoughtful auditioning of the two vocal settings versus the Flat mode, it's not difficult to get a great-sounding vocal recording. In the two musical modes—one for acoustic, one for electric—the EQ is altered a bit again.

You're most likely going to want a pop filter with the MV51. Of the USB mics we've tested, it seems to register the most plosives and breathing noises. A windscreen or pop filter will fix this easily, and there are even ways to make your own with coat hanger wire and nylon.
