I will have to say that I'm impressed with the attention to detail on these. It seems kind of odd that people find it worthwhile to make such an effort for a $90 mic. I think the font would be a pretty good indicator that they are, in fact, fakes. Looking inside would be an ultimate determiner of course. I think it would be funny and totally ironic if someone did some tests and found them to sound better than an SM57...(not that this would be too hard to do )...
Someone should do this and post clips. Seriously.
