After I removed the foam **** under the headphones they sounded clearer and had a bigger soundstage.
They sound great whether or not you remove this but it sounds(to me) better than it did when it was still on.
 
The bass isn't reduced either,the treble was slightly more open and it kinda felt slightly more transparent compared to when the foam rings where glued inside it.
 
So...exactly why are foam rings inside the headphone in the first place?

Did you remove the middle ring that sticks out? Or the outter ring thats flat?
