I have used similar type mics for both recording an orchestra, and in live situation for PA systems to audiences, although they were Sennheiser shot gun mics, then tried out some Beyer mics in a similar configuration with just as decent playback. Basically you cross the ends of the pair over each other, so that the dispersion pattern overlaps each other, A basic mic self mix were the on axis picks up the direct sounds along that axis and you get a stereo mix from 2 mics because of the overlapping fields with a small amount of separation. You can vary this to some extent by putting the mics further apart, but still have them crossing over each other along the main axis. This is also good for when you have a group of people as in a choir or even just a meeting.
As far as the foam and tights are concerned, the foam I have used both in live shows (audiences in excess of a few thousand) and in recording studios
no one notices to be honest and can be a quick fix where you don't have a pop filter that will slip over the end of the mic.
Behringer mics have been around for many years now and are pretty good, just less well known, unlike companies such as Sennheiser, AKG, Beyer Dynamic, Neumann etc which all charge a lot for their mics, particularly the last, but then again those are very good
