These are right on the ears. That was the main reason I disliked them, even with relatively flat ears they can hurt. Other ear pads loose the sound quality. The sound is based on proximity effect. They likely have similar if not the same drivers their K550-553 series has, which have thicker pads. When you'll push those against your head so your ears are against their drivers, you get a very similar bass heavy sound. When a driver is that close, ear shape, how far they stick out will play a larger role in giving some more bass or mids or treble than they may like.
Bad news: the release date for the wireless have been pushed to April. They did it with a prior failure of a folding headphone, that took a 1-2 year from its announcement to materialize, and it fit terribly with round smaller pads barely over ear, and due to the thickness of the pads lacked sub bass. They need to engineer these with better bass response at a distance, that is with a thicker set of pads to provide better comfort. Relying on a driver with less bass, and squashed ears against it to make up for it is not a practical design. AKG has some work to do, I think.
