It hums and annoying. I exchange it for another cable from the hum is gone. Measured, exchanged and tested with various portable devices ... it hums, without that I know why. May it be that the amplifier is too sensitive to the resistance. It may be that I only caught Monday models. It hums and annoying flat. Not very noisy and barely noticeable when listening to music, but because, the drone. And as this is so, when you have once seen it, I hear constantly back and hear it out, the hum.
