Pros: Great, great comfort. Very smooth treble. Great out of head experience. Convincing 3D imaging. Authoritive bass with great punch. Clarity. Detail.
Cons: Bass takes away from the balance & cohesiveness of the music. Dry & sterile with SS amping. Highs can appear to be a bit sharp & piercing.
I'm very fond of the DT880, but oddly enough, not when it comes to music. I find music with them dry & a bit sterile.. The DT880 demands tubes for musicality, Although, they are hard to fault in terms of technical merit. They offer excellent resolve, detail, & separation of the instruments.. The resolve is a bit superficial & docile compared to the DT48, but is still stellar in their own right, & what you would expect from a hi quality headphone worthy of it's 489.00 MSRP.
Unlike the SA5000, the detail isn't in the spotlight, getting in the way of the music.. You get just about the same amount of detail, but it doesn't take away your focus from the music. Detail isn't pushed in your like like the SA5000.
I find the DT880 to be the smoothest dynamic headphone I ever owned. Just butter smooth, only my Ortho's are smoother.. The treble high octane, plentiful, smoother & better extended then my DT48, which IMO, lacks the overall smoothness & treble energy that I really enjoy with the DT880.
