Hello everyone, I have already had the headset replaced once under warranty. The reason for this was that I permanently have a quiet but very annoying noise on the headphones. It doesn't matter whether the headset is connected wirelessly, by cable or via bluetooth to a device. The noise is even there when the headset is not connected to any device and is simply in "stand-by". With the replacement it was fine at the beginning, but after about an hour the same problem occurred again. Has anyone had similar experiences? Is it my headset or is that just the way it is with these headsets?
