Fit: I don’t have a particularly big head, and am usually about 1/3 of the way up from the smallest fit setting on most HPs. I am slightly over the mid-point toward the largest setting on the Immanis, though. Those with big noggins might find themselves maxing out the adjustment range. (@littlej0e , are you bumping against the end of the adjustment range?) I think I recall hearing about this before, though, and that Aleks was looking at a tweak. Overall comfort seems great, though.
The adjustment range could be improved, though it doesn't affect me personally. The last 1-2'ish notches seem irrelevant as they no longer suspend the pad from the bridge, causing the pad to bunch up at the adjustment point instead.
For reference, I have a pretty big melon and tend to position my ear holes slightly below and back from dead center.
