I got my email late afternoon the same day the kit arrived. I did notice in the email, they are actually giving me more than a week to try them out. They were delivered on 7-8, and the email says they need to be back to Klipsch by 7-22, but allow 2 days for shipping. I will allow at least 3 days to ship, so I know they make it there in time, so I'll send them by 7-19, that's 11 days. Very cool.
I'm with Muel, the choice is between the R6i and the X11i. The R6i is a very good deal for the money, but the X11i does sound more clear, fits better, and just seems more sleek and fashionable. The cable is smaller but I'm sure it's made well enough.
