Thanks for the tip. Yes, it was the buttom of my right ear leaking sound. I actually tried for about half hour to get a good fit. And I did lowered the ear cup. I tried every possible position I could think of, still I can't get the fit.
(I ended up buying DT770 Pro LE, which is very good sounding too)
