Anyone use or hear the KRK GoAux 3 or 4 and would like to share your experience?

Hi,

I can't seem to find any good review on YouTube, except for those who's genres don't align with mine.  I tend to create Rock and Country based music.

What's your opinions on the KRK GoAux, especially since those speakers can "tune themselves" to your room acoustics with a included microphone?  (I think the GoAux 4 was the only one to have the Mic.)

Don't know those, but my IKMultimedia iLoud MTM has an included mic to tune themselves too.
