If Sennheiser made a closed back HD560s that sounded basically the same (or at least same tonality, maybe deeper subbass extension, it would probably have smaller soundstage) I’d die a happy man. I currently use the 770s EQ’d to shit when I need closed back usage, but I’d love something that I didn’t feel the need to EQ (like the 560s) and that could be more portable (non-detachable coiled cable on 770 😭 it’s great on my desk but no where else) but still isolate nicely. I think I’d like to try the BeyerDynamic T70 - it’s pretty flat aside from the typical Mount Beyer treble spike
