These are my go to over-ear headphone at the moment, and will probably be for a long time. 

The good, great review, the bad, i have too buy them..

These are more semi-closed than closed. The V-Ports do allow for some leakage, but they are also what gives these headphones their bass, depth & soundstage. It's too bad these don't come with the 3-button cable, which I honestly believe is the best remote/mic cable you can find.

great review! my only issue with the wireless is that they don't fold down (which i think is a step backwards) i understand its probably to prevent the m100s from phasing out completely. cause they do advertise that they are a bit better the m100s and they also are wireless, for a marginal price increase. still though i feels a bit incomplete because of that. plus it would be nice if they included the xl pads as well (but maybe i'm being a bit greedy now) haha i'll wait for the next iterations! 

Giorgio Moroder a DJ? That's news to me.
Have you heard the Sony MDR 1ABT?
Also does this support AptX?
