I would go with with the newer Corsair Vengeance 1500 v2 Dolby 7.1 USB headset, unless the USB output limits your usage.
I would shop around other sites, looking up that model up on Amazon you can not only get the Corsair Vengeance 1500 for $25 dollars cheaper than the Website you are referring to, but also includes free shipping:
For $5 less you can get the 1400:
I guess since the site you are referring to is in Australia, Amazon isn't an option for electronic goods, but I would definitely shop around for a lower price.
My son uses a pair of Turtle Beach Ear Force X12 and he loves it, but it may not be up to your standards.
Good luck with your decision.
So I've decided to go and buy a new headset after my current one is getting a bit dodgy in some aspects.
I am limited to buying from this website: http://www.pccasegear.com
and I am quite confident in buying one of two Corsair headsets. I'm completely indecisive of which one though. One is a direct USB connection, and the other one is analogue that I would use with my Creative X-Fi XtremeGamer sound card.
First option: Corsair Vengeance 1500 v2 Dolby 7.1 USB Headset
(Note that this is virtual 7.1 surround sound with Dolby software)
Second option: Corsair Vengeance 1400 Analog Headset
(Note that this is stereo only)
My main concern is whether or not it is better to get the more recent 1500 model or the older 1400 model that I could use with my sound card.
I'm also open to suggestions of other headsets, although they need to be worth less than $110 on the website I mentioned. I'll be using the headset for the entire range of things from gaming to movies to music. I will be using the mic every day as well.
