Optical Digital Cable (TOSLINK) are not always unproblematic. As a bonus you get with the purchase of equipment at most the cheap and thin but very inflexible and knick-sensitive cost cables, their measly Steckerchen are either often only to push with force to connect or sit so weak at the other extreme, that they can fall out easily. Something heard without further delay directly in the trash!
With all these problems you have to deal with this very high-quality cables not bother! The cable is quite flexible, the plugs are large enough to pack it securely and do not sit firmly but too tight in the socket.
Because the price is still to be described as at least adequate, full five stars.
