When I needed a new pair of headphones, I went to guitar center and the salesman pointed me to the DT770s. Much better than going to the Apple store or Best Buy.
I love my DT770s. Reasonably priced, well-constructed, comfortable (if a bit warm after a while), no sound leakage, and of course they sound fantastic. I often see artists of the music I listen to wearing them too, must be a good sign.
