I respectfully disagree I own the K702 angled pads and they alter the sound quite a bit, too much to my liking.
I'd love to use them, really as they are really comfy but.. they just get too warm IMO.
The perceived increase in air was little to none and the decrease in imaging clearness was/detail retrieval was easily noticeable.
IMO, to my ears.
If the memory pads are even warmer then no way for me :/
When the K702 AE was released with the memory foam pads, a lot of comparisons between it and the Q701 (the last iteration at the time) and it was pretty clear what changes you got from them. Not discounting your perception at all. Just reiterating there was a large amount of the community who found differences in the signature from one pad to the other. I'm not debating which one is better (the angles pads, dammit!), but there was a clear difference.
