Tell us about yourself!
I did this about 16 years ago out of necessity. When tracking our drummer he wanted the play back so loud that we were getting bad bleed over on the mics. After that, anytime a pair broke (head band, wire fixed, etc.) and the drivers still worked I would run out and get another pair of work muffs and transplant them over. Here are two pics of the yellows and a shot of the whites for our vocalist. I also made two more pair into red muffs.
