Bose Noise Canceling Headphones Repair and New Pads

I bought some non-working Bose QC-2 headphones. I repair the battery holder, install new pads, and reattach the tweeter. The headphones are working great now!
Here are the pads: amzn.to/3AY2rti

Used your pencil with the eraser approach. Did it by hand, not with a drill. Fixed my headphones. Thanks.

Nice job. Better to fix than throw away - and more fun. Scrubby Pad = Scotch Brite (TM)

I have same pair , one side has no sound, I was going to throw away, until I seen this video, would you be willing to fix and keep it for yourself as a gift?
