Might be interesting if you sent that to Oratory1990 for measurement to see if it differs much from the previous HD600. He's found over here: https://www.reddit.com/r/oratory1990/wiki/index/list_of_presetsI've bought new version few days ago. Earpads look identical as HD6XX I had. Although headband paddings are two part (like HD6XX, HD660s), not four part like old HD600.
