I just requested the Nu Audio pro card using their upgrade program: . Looks like a great deal and I am really excited to see these improvements, even though I very much love the original. I noticed that I was only able to get the bundle (pro card and daughter card). Not a big deal for me, maybe someone will come out with real 7.1 headsets that are not total crap (I don't think that's even possible).
Currently I'm using the Sennheiser HD 650 paired with the original Nu Audio card. I know these headsets are used for music, however I am also using them for FPS gaming as well. It does not really bug me; I do hear where people/bombs are at on a map. That being said I am now more interested in other headsets to use for gaming only. @DannyW75 had a great recommendation on the DT 880's I am very much considering. I would love to see other (non 7.1) headphone recommendations using this new pro card. I am sure this would be useful for others in the community. Thanks in advance!
