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.
The Sound stage has more depth then width from my experience, & has a un canny ability to project sound in front of you, while at the same time projecting a very convincing out of 3D imaging that can actually cover my room.. But not in the 4 corner sense, but in the triangle sense. I never had this experience with a headphone before.
The DT880's bass is the most pleasurable I have heard SE.. It just has a mind of it's own mentality with authoritative drive & impact.. Under amped the bass can sound a bit loose, flabby, plodding. Well driven, it's truly as pleasure to listen too.. Full, textured, & well extended.
The most glaring flaw is the DT880 Mid range.. I find it a bit recessed, brittle, lean, & dry... Tube amps help, but still is not the headphones strong suit.
The highs are sweet with some bloom & sparkle.. But treble sensitive listeners will find the highs more harsh & sharp.. This is a area, where most problems occur with the majority of DT880 owners.
In general.. The DT880 are linear & neutral sounding compared to the majority of other popular hi fi headphones under 500.. For gaming & movies the DT880 are A number 1 in my book.. But for music, with the gear I used them with, they didn't do much for me.. Still highly recommended.
