[citation][nom]agnickolov[/nom]No technical data provided here, so I had to look it up on Corsair's web site. The dynamic range is 20Hz-20kHz, which is a very solid showing in contrast to all the other sub-par gaming headsets reviewed here on Tom's Hardware. However, it's still no match to a professional gaming headset like the Sennheiser PC 350 (10Hz-26kHz). I couldn't find HD 580 on Sennheiser's web site (discontinued I suppose), but the updated model HD 600 has a dynamic range of 12Hz-39kHz, so it's a different ball game again. In the author's defense, it's very hard to discern audio quality differences beyond 20kHz and many humans cannot do that.[/citation]
i dont think there's hardly any people who can hear above 20kHz (or below 20Hz). i remember we tried it in a science lesson at school, out of a class of about 30, there was only me and one other person who could hear a tone upto just over 18kHz.
I've always been under the impression 20Hz - 20kHz is the full range of human hearing. anything above or below that is pointless measuring, and of no use what so ever.
Anyway, this headset looks good. i've never done gaming with a proper headset before, and am rather tempted by this one.
