It's a simple cable, which signals even digitally transmits not much to say. The light signals arrive via a switch and another cable on the receiver. The workmanship is very good. The cable is firmly seated in the unit. The plug is firmly connected to the cable, the bending radius is good, the cable is not too tight. The male makes a very robust impression, because it is made of metal, with Platikverzierungen. The price is good for this length, it is not supplied adapter to 3.5mm plug. From me there is a strong buy recommendation.
