I'm looking into picking up a few wireless HH units for my pet sound company. I was looking into the Sennheiser Evolution wireless, partly because I'm a fan of Sennheiser, and have used them before, so I'm somewhat familiar. I was also looking at some of what AKG has to offer. The WMS400 from them looks intriguing. I'm just looking into ideas now. First I need to replace my EQs, then add EFX, then wireless after that, unless I find a deal on Ebay. Anyway, I'd like to open the floor up for debate. What are you all using? Do you like them, or not? And why? And I'm not talking about Nady or Samson.
