Hello, so recently i bought a pair of dt 990 pro 250 ohm's and i've paired them with a sound blaster x g5 external sound card. They recently have been making a buzzing/ rattling  noise in the right side so i decided to open them up and noticed a small black piece of ling underneath the cone part of the membrane and that it was slightly dented in as well. I couldn't manage to blow out the small piece of lint but I still  managed to get the dent out of the membrane. Now my right side just sounds like its distant and barely has any volume at all compared to the right side. Is there something i've possibly done wrong by chance? I didn't contact the drivers with any metal at all i used a plastic dull toothpick the try to get the lint out. This is literally my second pair within a month but the first pair had the left driver doa from amazon. All help is appreciated!

I would not admit to cracking them open(might negate the warranty) and just return them,and hope that the 3rd time is the charm

sorry for the delay had some stuff going on this week pretty busy, but as sides from that thanks for the suggestion I just might have to do so. It's maddening this is the second pair of bum cans.

Is there way to fix this myself by chance? Have you or anyone else heard of this? I'm in japan and shipping takes almost near a month so I was thinking of scavanging the right driver from my other dt 990 that was doa and only had the right driver working. Could it just be a bad driver by chance?
