Brief summary of my impressions:
For classical / jazz lovers, the K701 / Q701 choice. Very large, but somewhat unnatural, stage.
The DT 880 is a good all-rounder, who hardly afford mistakes. But in the long run it may sound too sober and neutral. The momentum is lost something.
For people who want to look for a low-priced all-rounder on the PC and thus enjoy movies or games, the DT 990 Pro is the perfect partner.
Its price-performance ratio is unbeatable.
The Edition version is worth paying extra unless one disturbs the spiral cable or you prefer a more natural minimal tuning.
The 600Ohm variant plays fine. But it is only to nuance.
The DT 1350 has an extremely high resolution and precision. In this discipline he comes close almost to the T 90.
So if one is looking KH is fun and with almost any style of music comes clear, can operate anywhere and is reasonably mobile, should the DT 1350 sample definitely hear.
The supra-aural design is certainly a matter of taste.
Who the vote of the DT 880 likes and wants have paired with high resolution and precision, should look at the T 90. Beyer-peak is also available here.
The Denon AH D 2000 can much quite good but nothing outstanding, but is closed and therefore for certain purposes beneficial.
The two Sennheiser models have the typical Sennheiser carpet and sound rather dull. They are therefore only suitable for lovers of this vote. The centers are easily stressed and very detailed, but the bass is quite sluggish.
Hope my experience will help you a little better classify the sound characteristics of the respective headphones ...

Addendum:
Meanwhile, I'm on the showpiece of Beyerdynamic, the T1, switched ...
The short version:
The genes of the DT880 are as recognizable as the close relationship to the T90.
Still playing the T1, for me, in another audio League.
Details can be found in my review of the T1.
