Shure SLX14/85 Lavalier Wireless System, H5

I've used these systems in a variety of settings - church, theater, for vocals and singing and wireless guitar. They are dependable, have good sound transmission. What else to say? Get the Countryman headset mic if you're doing a lot of speaking or singing. WELL worth the price (I know they're expensive). Easy to set up, easy to maintain. I take care of them pretty well, so don't know how well they handle abuse, but... you shouldn't abuse your sound system anyway.

Bought this for an association for when we have seminars. It works well, but the lavalier microphone is something of a disappointment -- you really have to have it close to your mouth for it to pick up the voice, and that isn't practical for most of our speakers.
