Hi @stefanh3 , Here’s a link to a video that shows how to partially dis-assemble your headphones. Once dis-assembled you can use an Ohmmeter to determine the connection problem between the left and right speakers. If it is a fractured wire in the swivel joint of the headband you may be able to work out how to pass a new wire through the headband. Although it also may be something as simple as a dry solder joint connection on the circuit board. You won’t know until you can determine what the problem actually is.
