I also had problems with fitting.. will try it with cotton! Thanks for the suggestion!    Do you just place on the bottom part or? 

Quote: they could seal better, yes. you mean some cloth or actual cotton? i have the grey ones too. even though i wanted the black but im glad in the end.  do you use some preset or? for the sound. 

First post and also one of the first owners of the capital headphones... So far I am pleased, even without burning them in. Using them on the galaxy s2 with a preset set to Techno/Dance.  I left them burn in with the pink noise last night. Will see if there is any difference.  Got the grey...
