I have an identical converter of Bigben, which is just like the Turtle Beach converter offered as accessories for games consoles. But I use it for something else, namely to the optical audio output of my LCD TV to be connected to an analog RCA input of my stereo. The seller has assured me that the adapter is also suitable and in fact it works beautifully. Sound and image are in perfect sync, and also sound and noise performance are perfectly fine. Practically I think it is that the converter is supplied with electricity from the TV via USB. He is therefore one with the TV on and off. This ensures that it is only turned on for as long as it is used.
