I need a mic to sing MPB/ POP music (MPB (música popular brasileira) is an acronym for Brazilian popular music.).

I am looking at a Sennheiser e845, e855 or AKG D880?

Thanks for any advice!

Does anyone have any experience with or know anything about the Sennheiser e900 series of dynamic mics? I've been able to find lots of into about the e800 series, but nothing about the 900 mics.
