So what is one to do if they also need a pair of closed backs?
I quite liked the Z1R's however my Utopia's are truly in a different league...
There really does not seem to be anything else (other than the Sony's) which can be a contender to those of us who already own the Utopia's.
Can these Pioneer's do the job?
How is their isolation - do they block everything out? Do they leak?
Well, they are not better or worse but different. Concerning comfort the Sony is lighter, wear comfort is almost equal so I think the Sony wins here.
Isolation and leakage is almost the same.
Well soundstage, I think there is no better closed headphone than the Sony at the moment
But the Pioneer does have IMHO the better sound and that's what it is almost all about
