From what I understand, sound cards in general can't really do anything for bluetooth and digital connections, as far as any of it's physical components go. I don't see bluetooth support listed there, and even if it was, the only thing that I know of that might help with bluetooth quality is software, or the bluetooth support options.
You could get a bluetooth adaptor however that focuses on sound for your computer, but this sound card won't do anything unless you physically plug in the headphone to the card.
