Very durable. Would prefer a 25 ft. version because 20 ft. always seems to be too short, but I couldn't find these in 25 ft. The on/off switch is a bit confusing to tell if on is depressed or if the button is raised (showing a white strip on the button itself). Other than that, this is a very sturdy cord with no sound problems. I believe I will get many months( if not years) of use out of it.
