I've owned a pair of these for about four years now and from the get-go they've surprised me every time I use them.
I have used them mostly for voiceover and podcasting. Now while they might not be at the level of the SM-7B, they certainly aren't far behind.
And in the difference in price and the gap becomes even smaller. In fact, I think I'd rather have a pair of these than one SM7.
Buildquality seems sturdy enough, they have a great weight to them.
Solid overall performance.
