Hello all Is it also the case that the headphones discharge after a very short time (approx. 2 days) even when not in use? If I leave the headphones in my backpack and don't plug them in, they are usually dead by the time I want to use them. At first, I thought that I had got a model that had been discontinued, so I had them replaced. This also seems to be the case with the new model. Who makes headphones that you want to have plugged in all the time when you want to use them? I am curious about your experiences...
