so i've been rocking a pair of DT-880 Premiums for nearly 6 years now and i'm looking for a change. the best thing is how comfortable they are (lighting clamping force) but perhaps they sound a bit "unexciting" for my purposes.

i've always had my eyes on the 6XX because of the price point and the fact i'd like to try out Sennheiser. the new 900 Pro X look really nice too.

one thing to consider is that these aren't only for mixing and mastering (personal music/passion project type stuff), but for general use and listening. essentially doubling as, and as close as i'll get - to a pair of "hi-fi" headphones, if you will.

that being said, which would you go for?
