- NiLeS, on 10/12/2007, -2/+17Right, but if you go to http://www.hackaday.com/entry/1234000490073630/ (the current story), you see this article. By linking straight to the story, zepequeno cuts down on people complaining!
- MrTea, on 10/12/2007, -0/+4if you're too lazy to do this, buy a Creative X-Fi series sound card for holophonic sound (CMSS-3D headphone)
- Otto, on 10/12/2007, -10/+14Surround headphones?!? I wonder if this guy realizes that he only has two ears.
For a speaker system, having more than two speakers is a good idea, because it creates a soundfield and surround sound audio works. You can hear things coming from behind you and such. With headphones and a good 2 channel mix, you don't need extra channels, because the sound of something coming from behind you is already mixed into the 2 channel mix.
Having headphones with more than 2 speakers is worthless. - rm999, on 10/12/2007, -0/+4i cannot believe this got modded down - it is very much true. Leaving downsampling of surround sound to software works much better than trying to stuff a bunch of speakers into headphones. Surround speakers make more sense (for example you can turn your head and keep the surround effect with speakers, plus the surround channels mix with the environment to create interesting reverbations and stuff).
- ivachen, on 10/12/2007, -0/+3Now you only need to turn the volumn to 1/3 of original for hearing damage.
- interiot, on 10/12/2007, -0/+3Or, simply listen audio recordings that were meant to accurately capture spatial information in only two channels (since we ultimately have only 2 ears, after all). To accurately record a realistic "head shadow", and to accurately capture how the pinna (external ear bits) alter the frequency response based on which direction a sound is coming from, some people have gone so far as to embed two microphones inside an acoustical dummy head.
If you have some normal 2D headphones, listen to these:

Headphones only have two speakers because you only have two eardrums.
Your ears physically can't interpret three-dimensions - your brain does that for you as you turn your head. The key: *turning your head*. You can't turn your head inside a pair of headphones. (Which is why nobody makes surround sound headphones.)
What he thinks is directional sound coming from behind him is actually just him being able to figure out when something comes out of the "front" and "rear" earbuds. He could accomplish the same thing by filtering the "front" and "rear" channels so that they sound different then sending the mix to a standard pair of headphones. - Genius16, on 10/12/2007, -3/+5Yeah as an old reader of headwize, this is.... really old. i mean, come on. this isnt new news. if someone wanted to make them they could easily find the plans. this is in no way innovative or new(s).
- freonchill, on 10/12/2007, -1/+3wish it had more information in the mod, e.g. images of construction, etc
- PayneX, on 10/12/2007, -0/+1I have to agree that cramming more speakers into headphones is far from an effective way of recreating 3D sound, and in the long run high definition holophonic audio will be the choice for headphones.
However, having more speakers in the headset does allow us to differentiate rear from front channels, which is certainly better than plain stereo.
Personally, the reason i bought my 5.1 headphones was because i have 5.1 movies and i wanted to ouput all those channels, seems to me that downsampling to stereo is kind of "wasteful".
Hopefully the future is indeed holophonic, the samples are mindblowing. - SpacePirate, on 10/12/2007, -1/+2If you have the technical experience necessary to do something like this, his information was more than enough. You need three pairs of earbud headphones, one pair of full-sized headphones, two splitters, and a dual channel sound system in your machine. Play with the levels to get the audio where you want it, and you're done.
- Knoton, on 10/12/2007, -0/+1I thinking a few people do make surround headphones, and the ones I have(Zalman) do make a difference although, yes there's less stereo separation so it becomes a little more difficult to detect where sound is coming from the effect is still there.

- radu79, on 10/12/2007, -0/+0Actually, you can turn your head inside the headphones. Well, sort of.
Some really expensive headphones have gyros and/or various other sensors, and they can detect the rotation of the head and adjust the signal accordingly.
And yes, Otto is perfectly right, we have two ears, so more than two headphones is useless.
The brian interprets the sound based on the volume difference and the delay. - Genius16, on 10/12/2007, -2/+1because the digg population has overgrown so much that were starting to get "normies" in here. the true sheep in the flock of the world.
but actually they do make surround sound headphones. you can buy a set from bose (i believe) but they are 2 speakers... they do something similar to making the sound holophonic. - radu79, on 10/12/2007, -4/+0duplicate post, sorry. wish there was a way to delete them.
- DougPenn, on 10/12/2007, -10/+5My surround headphones are my girlfriend's inner thighs.
- inactive, on 10/12/2007, -14/+2This doesn't look like hackaday to me. This looks like weadwize.com.
- jediboytj, on 10/12/2007, -19/+6I might as well say it before the "digg police" say it
