Headphoneus Supremus
Consider why all the $1k+ headphones (and some well below that like AT, Denon, AKG) are angling the drivers, angling the earpads, and remember one of the significant differences between HD600 and HD650 was the driver distance in the housing. And consider why many like Denon try to coax you by force into where you put your ear in the cup (with the front-shifted ovoid hole in the pads in the case of Denon.)
Because the R10 did it and despite decades of Apple marketing, Sony still defines any genre it gets into? Oh, you meant a less-historically rooted consideration...yeah, the whole bit about it improving positioning and staging also works until you consider a couple of wildcards like the K701.
