7.1 Surround Sound Headsets?

Question

How do these things work? I understand there are only 2 speakers. I also understand there's not a magical little fairy that works it.

Can anyone explain? I'm pretty tech savvy, but all the research I try to do on this leads me to forum threads from 2010 and 2011 before these things were ever really made on a normal basis.

Answer 1

They use off set drivers; time delay and frequency manipulation...it has to do with the way we hear things in a natural environment...One way our ears determine direction is the time difference it takes for a sound to enter one ear and then the other ear...also if a sound is behind use the frequency is different than if the sound is strait ahead mostly due to the shape of our ear..also the further a way the sound is the less high frequency it will have due to the fact that high frequencies dissipate sooner than lower frequencies do...there are also other clues our ear/ brain uses to determine sound...but its the manipulation of these perimeters artificially that causes us to think we are hearing direction and distance....

Answer 2

Have you actually tried them out? I suspect there could easily be 3 speakers in each phone. If they have put 2 tiny high band speakers in each for a total of 4 in each one, then, maybe. Other than that, maybe all they are saying is, they are compatible.

What does the plug for the whole headset look like?

A typical 3 position stereo plug can only give 3.1, Unless the head set is decoding a digital signal, then anything is possible.

Anything that is already stuck to your head, is only going to be able to increase the sense of surround, or sound motion by electronically manipulating the source materials phase delivery timing, echo, delay, poling, and volume, so on. Many older PC sound cards used to have settings that would do this, for example. Building some electronic fiddling circuit into earphones is , well, counter-productive? Cheesy? Anyway, whether there is one driver in the earphone, or ten, its still nailed right onto your ear, and by itself, can't do much more that sum up the output for all the channels and whack the composite into your ear, which most earphone out jacks already do. There are special recording techniques, that using ear-placed pickups (microphones) on what looks like a wig stand, to record performances, so that when wearing earphones, you get the same sense of space as if you were standing there in the recording studio yourself. its called binaural recording, but it is not used very much. Anything else is best left to the people who do the mix downs and will vary from album to album, in so far as what you hear through headphones.

Answer 4

I believe it works much the same way that Dolby Pro Logic II works. It takes a stereo signal and matrixes it into 6, 7 or 8 channels.
