Surround Sound Headphone. A gimmick? - Page 2

post #11 of 14
Just got my HD595's in today and that sounded awesome! I kinda freaked out a little and moved my head to the right at the end when he whispered in my left ear.

EDIT: I like the "improved" version too.

Our ears are designed for 360 degree coverage. Likewise, portions of our brain also account for sound positioning. If it was true, then you will no be able to determine sound behind, in front, or on your sides.

Surround sound in headphones is not a gimmick and through software emulation can give you better sound positioning from a stereo source. Sound quality is diminished due to the conversion of 6 channel audio being compressed into a stereo source. However, normally, on headphones with more than 2 speakers gives significantly lower quality then a pair of headphones unless they are designed to be "3-way" speakers.

Sound quality is best if you use the speakers for what they are. Software emulated surround sound takes in 6 channel audio (which gives more references to sort of "triangulate" sound better than a stereo source) and converts it into 2 channels. Dedicated surround speakers > Stereo headphones with software emulation > Multi-speakers headphones > Stereo Headphones; for best positioning. For sound quality, the list goes: Dedicated surround speakers > stereo headphones > emulated surround sound > multi-speaker headphones.

Technically wrong. Although the input can be multi channel sound, it doesn't have to be and can be stereo sound input. What many surround sound processing DSPs do is implement algorithms based on head-related transfer functions (HRTF), which is basically how we perceive directional cues from sound. When a sound is perceived from the right, the right ear receives the sound sooner than the left ear and vice versa. In headphones, as you cannot perceive the sound entering the right cup of the headphone to your left ear and vice versa, this results in lateralisation, which is basically why when listening to headphones, it sounds like 'two blobs' rather than a coherent directional sound. What surround sound DSPs do in headphones is introduce some of the signal that's directed to the right side to the left side (and vice versa) at a lower intensity (see quieter) and with latency so it sounds more realistic as that is what happens in real life when perceiving audio cues. In this case, lag is preferable

However there are other factors that affect your perception of directional cues and it is the size of your head and the shape of the pinna, the fleshy outer part of the ear with your identify as the ear. With a larger sized head, there is a greater distance between your ears and thus in turn there is a greater latency. Dolby headphone with it's presets, doesn't account for this well at all. Dolby Headphone really follows a 'one of three sizes fits all' policy, which in real life, doesn't apply at all.

There are other programs with account for this, such as Isone Pro (now ToneBoosters Isone) but requires knowledge of this and thus tweaking. However the results are fantastic and in turn more realistic than Dolby Headphone.

The pinna affects the frequency response in headphones thus why for headphones to be perfectly balanced sounding / neutral, it is not flatline. It's about +2-3dB in the bass frequencies with a large spike at 10K. As everyone's pinnas are different, you will perceive the intensity of sounds slightly differently from other people.

If the HRTF algorithm settings don't suit your ears, it will sound worse and egrade the sound.

Also properly positioned surround speakers are best but 90% of people dunno how to position speakers properly.

That headset is garbage. Only attracts the people who are like "OMG! MLG?! IT SHOULD BE PERFECT FOR GAMING! HAVE TO GET IT!"
$200 for that thing? Pftttt thats like buying some Beats.
