These are pictures from the first time they broke... I fell asleep while listening to them a couple times and I think that caused the breakage the first time. I got the repair center to send me a replacement part and a few weeks later the nut came loose, fell off and disappeared. I emailed them back about it asking for another screw, and she said I would need to send the headphones back in for repair. This really isn't necessary and I would prefer to not have to pay for those shipping costs and wait the three weeks for them to replace a screw.
Does anyone know where I can get one of the screws shown in the pictures below? (They are from the first time the screw broke.)
