I own a pair of M50 and am considering trading them for some K550 or DT770 for confort reasons. I also need good isolation, and tend to prefer flat sound signatures.
1) Sound signature: Since I own the M50, how does the DT770 compare to it? Are they both equally V shaped or is one more than the other?
2) Confort: K550 vs DT770?
3) Isolation: which one of the 3 models offer more? Which one offers less?
If you have experience with at least 2 of these cans, please answer the questions you are qualified to, and state how much time you have spent listening to each one.
