Are the two models MV7-S and MV7-K identical or different? In the "Specification" section, the specifications of the Shure MV7-S and MV7-K are not identical: the black model has no XLR output (although declared otherwise in the description, which is identical to that of the silver model). Furthermore, the size and weight do not match. I looked at some reviews of the MV7 and all black models had an XLR output. Are the two models really different, apart from their colour, or is this incorrect information? Also, one model is for broadcasting and the other for podcasting, why is that? Thank you for an enlightening answer.
