As the time goes by, I am starting to be really anxious and to think that my previous drivers sounded better and that i have lost this sound forever.
I have burned my PS1000e for about 35 hours. I don't believe the sound will really change. They sound harsh. Not as smooth as the previous drivers.
As I've said before, I do believe in burn in, but in my opinion, it's effect are noticable, but pretty subtle.
In other words, if you like a pair of headphones that's fresh out of the box, you might end up loving them, after they're burned in.
That being said, I seriously doubt that burn in will make enough of a difference, to make your PS1000s go from sounding ''harsh'', to to sounding sweet.
I don't want to speculate as to why your PS1000e sound different, but I have heard,, and read, about so many cases of sample to sample differences that I don't doubt for one second that your headphones don.t sound exactly like they did before.
