The usual toslink are very thin and somewhat rigid generally. They are usually covered with a thin, relatively resistant plastic. I have two such cables in use, one of which is already at least 15 years. At both the plastic sheathing is already scraped, already very strong with a cable. This I replaced now by the cable directly. The processing of this cable is perfect. The gold-plated plugs are sheathed with solid metal sleeves. Thus, the connectors are of course noticeably bigger than the usual from the cables. With very limited space behind the unit to which you connect the cable, it might thus be any problems. The cable itself has a cross-section of 5 mm and is surrounded by a soft, flexible sheath. This is very solid; the entire cable seems to me to be very robust and durable. The plugs were a perfect fit. Other reviewers have reported initially very achwergängigen plugs, which I can not confirm. The cable length is 1,96 m, there are the two 4 cm long plug. In this respect determines the length specification of the cable, which I have already experienced differently, often the cables are shorter than indicated. The main task of the cable is, of course, to transmit the audio signals. And this task fulfilled it properly. Conclusion: The cable is suitable for high-quality equipment. Due to the quality of the material used and the high quality of processing, I can imagine that the cable also frequent mating cycles without complaint survives due to its flexibility and is also suitable for mobile use. Overall, the other cable Direct cable appear to be very well made; I still have a headphone extension cable, with which I am also very satisfied.
