I did the "mod" on mine where you remove the foam piece from behind the speaker but I don't know if there is a real difference, what do you think? And what effect would happen if I was to cover the whole grill with foam instead of the one small piece that comes with them out of the factory?
 
i think itd sound bad if you do that. its just like bookshelf speakers that have openings in the back so that air can go out making the bass response and making the speakers themselvs sound better. honestly i think itd sound muddy, but hey who knows why dont u try it?

A question like this belongs on Head-Fi. If there isn't someone who has already tried that, there will be someone knowledgeable who can probably tell you what to expect.
 
I did this to my HD485 a few years ago, it made them sound a little bit clearer and airy. But if it sound the same to you.... I would just put them back on.
 
If the sound were better by removing stuff, I think Sennheiser would have never put the stuff there to begin with. As an owner of HD-555s myself, I can tell you that the best mod. to get better sound is to replace them with better headphones.
 
Just leave em' alone. I had a friend do that to a new pair of HD-555's and he wound up f'ng the whole thing up. Needless to say, if you know for certain it's going to garner better quality of audio- at least know what you're doing.
