@SonicElectronix thanks for providing this opportunity and sharing the information with our community. IMO, you need to mention the below info in the first post. Thus, can prevent some confusion in the first place:
"YOU MUST BE A LEGAL U.S. RESIDENT RESIDING IN ONE OF THE FIFTY (50) UNITED STATES OR THE DISTRICT OF COLUMBIA THROUGHOUT THE PROMOTION PERIOD AND 18 YEARS OF AGE (19 in AL or NE) OR OLDER AT THE TIME OF PARTICIPATION."
I believe that's correct. I actually don't remember. I think this further supports my thoughts on the 630 that while it looks peculiar in pictures, it doesn't look all that odd in person...and the sound is on point IMO.
I'm strongly considering them for work. I've been looking around for a good closed headphone, with isolation being almost as important as sound quality. And I can't wear IEMs all day. The fact these have an in-line mic for Skype is a huge bonus.
Waiting for reviews first though. If they're closer to the HD600/650 than the Momentums in sound signature they'll be near the top of the list. Assuming isolation is good enough.
