Basic cheap patch cables, good for occasional/hobbyist use.
In my set one of the cables got contact issues out of the box, and the rest tend to be 'scratchy', too. It's weird just by looking at it, looks like a solid build. At ~1 EUR per cable I guess this is what you get.
I like them being colored, though. Makes it easier to identify and adds a bit of 'color' to you gear (sorry for the pun).
