What screwdriver is need for beats studio 2.0
I recently broke my beats while falling down with them. The plastic headband near the hinge broke and I need to replace the top part of the headband in order to fix them but I don't know what screwdriver I need to unscrew the screws on the hinges. Anyone know what size the screwdriver is as well?
