Cleaning and Replacing Headphone pads

Just a test video of a small project.
Replacement pads of BOSE AE style headphone pads.
The pads were all worn out and torn but they still had great sound. I thought it was going to be harder to replace the pads but I'm glad to see it was a simple replacement.
While I was at it I thought it would clean out the speakers. Its amazing how gross these things get.
