I bought this headphone to connect to my philips DVD player. But my DVD player got only one Coax input. I was told that I would not be able to connect my headphone using that connection. Atleast I want to use it with my computer. Tied Analog but the disturbance and noise is way to much. Can anyone specify supported sound cards that has got digital optical input to connect to this headphone using sony POC-15A cable that they had provided along with the headphone.
