I needed a noise canceling microphone for speech dictation so I decided to get a gaming headphone and perhaps get something new and better in music listening at no extra cost. Consequently I read many reviews on Amazon.com on headsets that I thought might be suitable. I do not gain I just wanted good music listening and a noise canceling mic for my speech dictation. After reading many reviews I decided to get a plantronics 780 headset. And once it arrived I was amazed at how much it improved my music listening over what I thought was a very good stereo speaker system enhanced by the sound manipulation tricks of an USB Creative Labs sound card.
Even though the Plantronics 780 headset is not proving durable it sound is a spectacular improvement over the speakers I was listening to music on. This headset is said to have "Dolby Headphone" and are powered by a USB connector which also provides the Dolby headphone via its software. It has a switch which turns of the Dolby headphone off and on according to the manufacturers forum. However there were only a few music video files I was able to hear the difference on when supposedly switching the Dolby headset off and on on. The mother lode of improvement appears to occur by its simulation of a 7.1 surround speaker system. So this evokes my many questions I have on how this computer headphone audio system stuff works.
It seems like you should be able to create comparatively cheap new high fidelity headphone system using headphones instead of speakers, but when you go to other arrangements than the just USB connector powering the headphones directly from software how does it work? I see a lot of headphones talked about on this site with no mention of software or even a USB connector. But they talk of big or small soundstages which implies to me simulated surround sound. So how are all the ways it could work. Can you use software plus a USB powered headphone amp or do you need special amp or USB soundcard for processing or do you just have to have a sound card for the best audio?
I also do not understand if virtual speakers and surround sound I something different? I obtained a copy of PowerDVD13 which is said to be able to decode Dolby 5.1 sound and watching a music video, which had this kind of sound, the sound is just fantastic. So what are all the ways of getting this Dolby 5.1 sound to power a virtual set headphone speakers.
