After using the dt 770 pro and noticing the sound change overtime, and looking at Oratory1990 FR for new pads and old pads. I think that pads wearing off could be one of the main reasons causing people to believe that burn-in exists. At least that was the case for me while using the 770.
Edit: to rephrase and make what I meant clearer, I'm trying to figure out why burn-in exists. I suggested that pad wear is portrait as/perceived as/mistaken for burn-in. I repeat I'm not trying to say pad wear is burn-in. Its what make people believe burn-in is true.

Yes. I replaced 990 Pro pads yesterday, can confirm that sound change is real and very noticeable. You can find my post in my history I think. There is an useful link in the comments to the measurements of 770 and 990 before and after pad change.
