Saw the post for the in-ear version of the headphones (https://www.ozbargain.com.au/node/167985) posted earlier.
I hit staticice and lo and behold at the top of the list for the same price was the full sized headphones.
Cnet Review wasn't too great http://www.cnet.com/au/products/nokia-purity-hd/ but..a bargain is a bargain.
I suspect these headsets will be discontinued as the Microsoft Store US has the in-ear versions for a mere 30 bucks.

Although the RRP is substantially inflated, it is currently the cheapest i can find atm.
