You're asking for impressions about headphones that have only just been released, and have barely been circulated. At this point, you either need to show a little patience, or bite the bullet, and buy them. I'd recommend buying them from someone with a good return policy, in case you don't like them.
The focus of this particular forum is entertaining discussion. We're not a buying research service or an encyclopedia. There's a lot of good information here, but you need to remember that you'renot paying any of us to be your personal researcher.
