I dunno .... headsets still look like you should be teaching an aerobics class, unless it's the super teeny, almost invisible ones that the stars use, and they probably cost thousands.
I also think there is no need for wireless when you're tied to the kb anyway. I'd never just walk out in a crowd with a headset unless I was an emcee introducing a party .... or Monty Hall announcing a game show. Drummers should have one, but a front person (or soloist) should have the best sound available. The bargain headsets just don't cut it.
