Stacy, first of all, I have been remiss. I happily welcome you here! I know you well enough to know you'll love it.
And now....The flip side. Shures are more highly recommended for karaoke use. Why? Senns definitely produce clear crisp sound- an absolutely beautiful mic. However, they are TOO good for karaoke. VERY unforgiving. Whereas they are great for top singers who know how to use the mic, that's not the majority of karaoke singers. The Senn is so good that it picks up every flaw, impediment , key drift, or anything else. A singer that sounds "pretty good" with a Shure may well sound, um......LESS than pretty good with a Senn..
The original post doesn't mention the purpose for the mic. If he's a pro singer looking for one to bring to gigs with his band, then a Senn. If he is only announcing for his DJ work, 1) It's too much to pay for that purpose alone, and 2) Even then he must have a good speaking voice, and if he's singing he has to be dead on....
So, GENERALLY speaking, for karaoke DEFINITELY Shure, for straight DJ work probably the same....
