I just wanted to share that I did my first show with a new Sennheiser E 835. I couldn't be happier with this microphone. It's the same price as an Audix OM-2 or Shure SM58, and worked great for karaoke. The sound is good with a bit of reverb and no EQ, its feedback rejection is great, and the sensitivity was phenomenal! The little PA I'm borrowing had to be turned way up for the other two mics, but the E835 sounded strong halfway up even with a foam windscreen on it. (Part of the reason for that might have been my mixed cables, though.) And like a lot of reviews I've read say, the E835 gives consistent sound with people at varying distances and angles to the mic, which helps with so many different singers.
My other stage mic is an Audix OM-5, and I have to admit this cheaper Sennheiser was a better investment for me. Even my musician friend who's a big Audix fan was impressed by the E835. And the Sennheiser just looks cooler too.
You can't go wrong with this mic. Just be warned that it's kinda fat, and won't fit most slide-in mic stand clips. Sennheiser includes a snap-in clip in the package that will fit a wide range of mics, but I'm probably going to get a bigger slide-in clip for stage use. People aren't too keen on how to put it back!
