I"ve had both the Senn 570s and the 280s. I ended up trading the 570s to a friend and kept the 280s. For my type of music I preferred the closed type. IMO they are a more balanced headphone. I don't know how to explain it other than the music just sounds better to me on the 280s. They will definitely cut out quite a bit of the background noise.
