Tiandirenhe for Sennheiser HD598 HD599 HD569 HD560s HD559 Replacement Cable HD518 HD519 HD558 HD579 CS SE SR Headset Upgraded Cable Headphones, Length 1.8m/5.9 Feet (3.5mm to 2.5mm)

quite good quality. was looking for something shorter and didn't pay attention to the length before ordering. but still happy.

Solid cable, fits my HD518 like a glove.

It is a well constructed cable. Seems to be a long life component.

Le câble se tord sur lui même.

I was skeptical as to whether this would work well enough. It worked perfectly though. The only downside is that my 599SE headphone came with a 9ft cable initially and this one was only 6ft. Not a major issue, just something to note. I've been using it for several hours with no noticeable difference in quality. I truly assumed an off brand cable wasn't going to be as good. Glad it worked out through. It was a $9 fix instead of spending $100 on a new set of headphones. If you're having issues with your Seenheiser headphones, I'd look into a replacement cable to see if that's the issue. Mine were used daily for up to 10 hours a day for 4+ years and I guess that's what did the cable it. No clue. But it seems it's a fairly common problem after a while. But consider this cable, or this brand, if you need a replacement.
