Don't worry about it because I got the softskin pads and unfortunately the news isn't good. While they increased the bass quantity and impact a bit, which was nice, they made the mids bloated, nasally, and almost echoey. And pretty severely so. I couldn't take it and I've put the velours back on my DT880 and put the softskins on my DT770 and they are doing better with them. There's still a boomy-ness to it but it offsets the DT770's recessed mids somewhat. I'll have to listen some more before I make a final decision on using these with the DT770s but I wouldn't recommend them with the DT880. These are the EDT770S softskins by the way. I'll probably snag a set of EDT990S just to see how they sound.
It's a shame because the pads are fairly high quality in feel and appearance, they're quite comfortable, and they look good on the DT880 Pros. They match the leather headband perfectly.
EDIT: I may have to retract what I said. I didn't use the "foam plates" (as Beyer's manual calls them) that came with the softskins, that's the foam piece that goes over the driver and under the pads, because they looked identical to the ones my DT880 came with as well as the ones that came with my black velours so I didn't bother. However, the "foam plates" on my DT770 are different (thinner and not grey on the back) so I tried the softskin's foam plates on the DT770 and they sound better now. I'm going to give this more time and possibly try the softskins on the DT880 again this time with their own foam plates and I'll let you know.
