I have a sound card with an audio breakout box that I use for my home studio, but the original cable that came with it only has three long legs. Because it is an obsolete product, the company no longer makes patch cords, even longer ones. I was afraid that this product might have different internal wiring than the original one, but I decided to give it a try. It fits and works absolutely perfectly. In the attached picture you can see the new cable at the back left.
