Yeah, I agree with what Spud said. Try some out. Beta 58s didn't really do it for me. Clearer than an SM58 but I found them a bit too sibilant for me personally. I actually liked a Beta 57 on my voice more, but it has a very small window to sing into, so if you move around a lot live then it's probably not the most practical in that way.
I thought the AKG D5s were an ok option around this price point. But I just always went back to a 58. Are there better sounding mics? Absolutely. But I'm yet to ever be let down by a 58.
Except for their 'awful' sound that was good enough for a million famous bands
As Beeg said, the Ben's excel in this area. We eagerly await their educated opinions.
