i fixed a headphone, an old Sennheiser. one of the wires to the driver, thinner than a hair was broken. also the diaphragm of the other was crumpled a bit causing vibrations and buzzing. seems to be fixed now, well with my luck, for now...
also don't know why everything looks so grainy and dirty on the picture. it's not in real life
@gryvix Must be the vibrations and buzzing 🤪 Good job on the repair though!
