I'll try my hardest. At the moment, they have the velour pads mounted on the headphones, in which the pads are in great shape. The pads are of the older variety (thin, clear plastic backing) which connects to the cup assembly. This older method can be "iffy" to remove and re-install the pads and there are times when the pad tabs can snap. As it stands, the velour pads are nice and tightly attached to the headphones - in fact, much tighter than the newer black rings with the 4 tabs. I'm not sure if I should disrupt the pads at this time or not until they need to be replaced. I'll have to spend time with the headphones and see how the sound works out.
I know a way of improving the older velour pads actually (I have a pair myself from the accessories that came with my original HE500), just take them off your headphone, and use double-sided adhesive tape, tape the modern mounting rings onto the back of the old velours. It fixes the installation problem outright and from what listening tests I've done, does not change the sound at all.
The reason it doesn't change the sound is probably because the clear plastic "plate" is already blocking any sound from conducting through the earpad. It consequently really weakens bass extension just FYI.
