best headphones 7.1 surround
image
I'm thinking of buying the nvidia gtx 470, it apparently has hdmi that supports 7.1 surround sound, What I want to know is how am I supposed to get the sound from the hdmi port? How do I get the sound from the surround sound hdmi port over my headphones? If it has surround sound hdmi then how do I get it connected to my headphones?
Answer
Headphones? you don't. surround sound requires multiple speakers. 5.1 = 5 speakers and a sub, 7.1 = 7 speakers and a sub. Headphones consist of 2 speakers so you get stereo. "Surround Sound" has more to do with how the audio tracks have been mixed and recorded then separating the tracks and sending them to the individual speakers during playback. There is such a thing as "virtual surround sound" where multiple tracks are sent to the same speaker that does sound slightly better than just regular stereo, but it is still only 2 speakers and coming to you from only 2 directions so it is still stereo instead of "surrounding" you with sound from multiple speakers coming from multiple directions.

All the in game audio options have either Dolby 5.1 or Dolby pro logic 2 settings, which one has the better sound quality for my headset? Any information would be greatly appreciated, thank you
Answer
= Dolby Digital 5.1 = real discrete surround sound encoded audio > Dolby Pro Logic II or DTS:Neo 6 takes stereo encoded audio and matrix upmixes it into a fake 5.1 surround sound format for surround sound speakers.
= Any stereo/2.0 channels of audio speakers/headphones will work with a virtual effect such as DTS Surround Sensation/DTS Headphone:X or Dolby Virtual Speaker and Dolby Headphones. = Media players like k-lite codec pack for media player classic or vlc player or kmplayer have a audio setting called Headphone Virtual Spatialization which is the same thing, which takes any stereo speaker/headphones and creates a virtual/fake surround sound effect (special surround sound headphones may only have that virtual surround sound effect built into them, that's the only difference).
