Those drivers can be damaged easily. You may want to do something like this to protect them:

So, I decided to go further, and take off foam from back sides, then place it inside the earcup right behind the unprotected driver (with no stock grill on it). Now they're not over ear, but on ear. Also i take that cheap and sticky surface from cushions - now they felt like velour, very comfortable! They finally sound better now, and everyone who have UR40 can do this mod for free.
