'sup guys. Using HP-1 here, overall I'm pretty satisfied with its sound accuracy, and it's double as a wow factor among my friends. Haha.. Tho I must say, the bass is lacking. But I do enjoy the vibrating effect when there's explosion around me

I've been using Roccat Kave for a while now (well, sitting next to my monitor for a while now exactly), and the rubber coating at both sides has become sticky. Any idea how to remove the rubber coating completely?
