I think they look pretty funky, and personally wouldn't want them. But this only means that there is more to come. In a few years wired headphones will go the way of the wired phone
I wouldn't get too excited. Wireless headphones don't really seem to impress very much. The technology simply isn't there yet - and if it is, you're gonna pay premium for it.
However, like most things, soon wireless will be the standard.
They look mega-dorky. Etymotic are unlikely to put out a turkey though, it should sound at least decent. But you might want to wait for Shure's response (if there is one) - they have more product development knowhow so might come out with something a bit sleeker.
