The adapter works 100% and as it should. Given the many bad reviews I was apprehensive at first, but at the low price of the attempt wars worth it. The many bad reviews in my opinion, come from the fact that in the adapter a normal, imaginary analog audio, 3.5mm jack plugs. That can not work, of course yes. The adapter carries the light signal from toslink only 1 to 1 on, it takes place here by no means a conversion into an electrical audio signal. So a 'normal' 3.5mm jack will only reflect the light.
Moreover, I have nothing to complain about. The adapter is firmly seated in the Toslink connector and the optical plug snaps firmly into the adapter. That such an adapter no major mechanical load should be suspended, should be obvious. The problems causing transmission interruptions by loose fit of the cable to the adapter or the adapter in the device, I have not. I can easily move the cable during music playback or shake the adapter.
