So first: The sound quality of these headphones I find really good and I am therefore very pleased. Take this every day in the car and would not want to miss this since.
About the processing can argue however. As I am told now the second headset is broken in the same place. Dear Panasonic people, why one gets the idea that earcups with Plastikklips to the support stuck to? No one who had something to do with Plastikklips will come even to the idea of trying the ear decrease. For the mobility there are also certain other ways to connect two components to produce.
Pay me now so look for another.
