Very good cable with excellent price / performance

I use the cable especially to my smart phone from time to connect to the time of my system. The workmanship is very good and the screw type connectors are soldered clean.
Through its "thickness" of cable sheathing is relatively stiff thing you should consider. For the cable but does not generate any, perceived by me interference frequencies.
The plug is the contrary of my previous speaker, with me properly fixed and has no leeway, possibly small manufacturing tolerances?
