Not much to talk about, I tried these out on dt770s and my Razer kraken and it fits both, it fits a bit better on the kraken than the dt770s but for the amount of headphones out there I know that this is just the nature of mass produced for wide use and not specific models so it's not a huge deal to me. They're easily a step up than the stock kraken pads and I always enjoy the quality of the sheepskin pads.
