Condensers are very sensitive at a distance and pick up everything including reflections from walls, ceilings, floors, pipes, mirrors, furniture, cars passing outside, the lot. For a good condenser, you need a good sound-damped room
After much cash spent on Neumanns, etc., I got a Shure SM7B (
http://www.sweetwater.com/store/detail/SM7B). It is a dynamic, not a condenser and ideal for non-ideal recording environments.
It is absolutely pop-proof, I only need a popshield to stop artists spit hitting it. (!?!)
And it has switches on the back to set the frequency response. I prefer Flat with Bass Rolloff set to ON. Some like the Presence boost setting which gives you the classic Shure SM58 rock mic upper frequency boost. Two-in-one.
It admittedly does have a low output, but unless I am recording a weak voice, my very basic Cakewalk/Edirol UA-25EX interface has always had plenty gain to spare.
