I am wondering how people compare the two? What are some flaws of both and what are some benefits to both? I am wondering because I bought a pair of Sennheiser HD 598's to compare to my Beats Studios, but I realize that they are not the same kind of headphones at all and I wanted others opinions before I make my review of the two. Does anyone own professional headphones like Sennheiser that can compare a model of such to the Beats? And I would like to hear peoples opinions on which they prefer, open or closed.
