I'm using these Ear Pads on the very old version of the Beyerdynamic DT 880 i got from my father. Befor mounting the ear pads i warmed them a little bit with an hairdryer. You have to be very carefull with the flexible plastic you slip over the headphones. But if you do, it is even possible to change them am view times.
I was shocked how much the Ear pads influencing the sound of the Headphones:
You can not use the velour version for the old DT 880! I don't know why but there is no bass if you do. But with this version the sound ist as good as usual.
