Excellent Mic For Many Reasons
I have compared this mic with an SM58, Sennheiser e935 and an Audio Technica AE4100. This mic, and the last two are all fairly equal and excellent in their own way.
I've read that it has problems with feedbacking and popping, but this is not true - we use this mic at a very high levels in our band (alternative rock, we play loud) and there are no issues at all. I've also read that some people find it overly bright or dark, also not true - it is fairly natural (check the EQ graph) and you will not need to adjust much, if any, EQ. You may notice an increased proximity effect when you approach the mic within a couple inches, but this is a condenser and it's quite normal. You can make use of this effect, or roll off bass EQ if you don't want it and still want/need to sing close to the mic.
It is also built well and solid (made in Poland, not Austria), but that isn't normally an issue with live application mics.
