The plugs sitting not so tight like original do. However the overall quality is good. I hear no problems with the sound.
Really good cable. Red part od the cable is nice and soft silicone like material. Not too thin, not too thick. Core part od the cable is coated in nylon or whatever that is. It is not textile for sure so it is not soft to touch, but it is not stiff either. Connectors fit perfectly to the cans. Overall I am very satisfied. It does feel like a cable you want to use on your 300+ usd headphones. Tested with HD660s.
