I would almost agree ^
for me that is a really hard one.
because the yamaha still has the edge on the pro in soundstage depth and width the piano strikes can be more captivating in placement it would depend on the notes played. Both have very great tones which I think sets them apart from their competition because they are very real. A piano strike would sound equally hard on both with good decay and tone but the low midrange notes would sound better on the pro and the upper midrange notes would sound better on the yamaha. Given that the pro upper mids are not recessed I would say that the tonal balance of the pro may be a tad more accurate but the yamaha lower mids only sound recessed next to the pro and sony 7520.
the 220 are really easy to come off and have more pad swapping options.
I am really liking both headphones and thought one would have to go very soon but I want to keep both of them now. The yamaha is holding up very nicely against the pro but the pro balance is great.
The yamaha would be more suitable for modern studios and the pro less so.
I would tune a bass line on the pro but make sure it isnt too loud in the mix with the yamaha. Then go back on the pro and make sure it isnt too soft
