Are they easy to remove/install in case you want to go back to universal tips? Just curious... These customs do look awesome, especially for travel on flights, since I may be going to China for work in a couple months.
Also, how do you remove the foam out of the Senn case? I tried tugging on it, but it didn't want to budge, and I don't want it tearing and leaving chunks behind. I'd like to preserve the foam as best as possible once it's out.
