I have been hearing about the Tritton AXPros, but I haven't had a chance to hear for myself but if these or that one being mention in the article are stated as better than the X4 Turtle Beach I'm all ears.

Does anyone here know any better?]]>Jan 6th 2009 11:33AMhttp://hd.engadget.com/2009/01/06/psyko-audios-5-1-surround-sound-headphones-actually-look-psycho/http://hd.engadget.com/2009/01/06/psyko-audios-5-1-surround-sound-headphones-actually-look-psycho/Most reviews that I've read trying both lean towards DOLBY HEADPHONE over multiple drivers, but it's a mixed bag, so in the end you would have to decide what sounds best to you.]]>Jan 6th 2009 12:23PMhttp://hd.engadget.com/2009/01/06/psyko-audios-5-1-surround-sound-headphones-actually-look-psycho/http://hd.engadget.com/2009/01/06/psyko-audios-5-1-surround-sound-headphones-actually-look-psycho/
First, about the left and right signals:
If you are thinking about the traditional headphone methods, consider that the multiple driver method puts right sounds only in your right ear, left sounds only in your left ear. That doesn't seem like a big problem, but there are a couple of problems with it. First, the psychoacoustic research says that if you play a sound in only one ear it sounds 6db quieter than if the sound is delivered with the correct timing and volume delays to both ears. Every sound you normally hear goes to both ears with those timing and volume differences. The psychoacoustic research even has a term for the effect of traditional headphones - it is called in-the-head-fatigue syndrome. That is the effect that many people feel after using headphones for a while. Their brain actually tires from trying to figure out the direction of the headphone sounds that don't make sense.

Psyko's headphones play every sound with the correct timing and volume difference to both ears. Just like being in a room with the sound.

Second: about perceiving front and rear sounds.
The way sounds are perceived as being either from the front or the rear is due to how the sound reflects off the outer ear. Since every ear is unique to each person, just like fingerprints, that means every signal at the ear drum is unique to each person. The DSP methods, like Dolby Headphone, deliver a single signal. It is like one pair of prescription glasses for everyone in the world. If your prescription, or ear shape, happens to match the DSP algorthm it sounds good, but if your ear shape is outside that algorthm it does not sound natural.

The Psyko method provides a sound flow from the front and from the rear of the ear and reflects off the ear to create the correct signal at your ear drum. Plus Psyko's method results in no latency because there is no DSP, no signal processing.
