Looks to be decent availability around Melbourne and Sydney. C&C only.
The CORSAIR HS60 PRO SURROUND Gaming Headset delivers both comfort and quality with memory foam ear pads, custom-tuned 50mm neodymium audio drivers, and a detachable noise-cancelling unidirectional microphone.
Might be a price error based on a quick google - everyone else is around the $90-100 mark.
Fairly firm ear cups in case anyone is wondering. I also have the Arctis 3 and prefer them as the cups are much softer.
