Connector require excessive force when one-and unplugging

However, the connector must be pressed with considerable force into the corresponding sockets until they click into place. But they then sit bombproof. Only one has then later as his difficulty unplug again. With a DVD player I had the same socket tear the fear in even more effort on the force. That's definitely a bit too much of a good thing. When plug in a cheap Toslinkverteiler of Ligawo its sleeves have been pushed into the same housing. The brand appliances have the plugging and unplugging but without damage survived. I would not want to bother my equipment regularly. So for mobile use, these cables are rather unsuitable, except the device sockets drone through the use of this cable out over time and then it may go in the future more easily. But if then still hold other cable with plastic plugs?
