I was trying to repair a headphone and a screw from the earcup got attracted onto the driver, while trying to take it out, the screw got moved around on the center bump of the driver, this left a large depression and many smaller ones on the driver. Will this affect sound quality, how can I repair it?

There is a grill over the driver, so I cannot use the cello tape method, I tried taking out the driver from behind but it is stuck with some strong adhesive. Is there any possibility of ever regaining it's original sound quality in that driver?

Would it be possible to use a straw or something similar to suck the depression out?
Good luck.

Thanks for this suggestion. I tried using a mini vacuum cleaner with a straw attached, it was able to reduce the depression in the center, but there is some depression towards the side, and I'm unable to insert the straw or anything to reach that area because of the grill.

Do these depression affect sound quality outputted by that driver?

maybe try using a piece of scotch tape. land the corner of tape gently in the depressed location let it stick to the surface then pull up....

Tried that and it didn't improve. The voice coil came off with the membrane from the magnet, should it be fixed inside or come out with membrane?
