I switched from Shure to Senneiser years ago when I found there was more than an SM58. I use a Sennheiser 935 plus 3 others for Karaoke.

As far as wireless goes, I have had my trusty Sennheiser E100 headset for years and never a complaint. I also have an E100G3 wireless with an E815 handheld dynamic for roaming around. I know Gary swore by his Countryman, which, I am sure, is very good also.
