$69.99 + shipping & handling of $10.22 USD ~ AU $105
No. 1 best selling computer headset on Amazon. 4,271 customer reviews averaging 3.8/5 stars.
Cheapest on staticice is $158 picked up @ MSY.
Also a good price is the wired model being the Logitech G35 at $92 AU delivered.
I use this headset and I would say these are way too good. Only thing is that you need to install software to use surround sound.
