hd6xx users, can you help me with something 2018-09-29 12:57:13 https://imgur.com/a/G4ihihBWhile I'm taking off the headphone, my glasses were taken off accidentally, and their hinge frames on the both side have put against the inside of the ear cup. The clamping force sustained the glasses on the air for a moment.https://imgur.com/a/llOQoONThe spot was somewhere around the red-colored. I went ahead and took out the earpads to check the possible damage inside, but I saw nothing particular.https://imgur.com/a/mPekoZtRight now, I'm going paranoia, and every sometimes I think I hear strange noises.My question is:the red-colored part in the second image, is it vulnerable? 'though I see no visible damage.. I'm really worried.
