For anyone who is in the market for noise-cancelling headphones, the Jabra Elite 85h might tickle your fancy. While not as great at ANC as the big players, Sony and Bose, it does possess a few attributes that the other two don't have. Plus, for the price, I wouldn't consider that a deal-breaker.

I am not sure when the deal expires. It's probably best to pay in USD as Amazon's currency conversion isn't always pro-customer.
The price changed to $299 in cart, $10.85 delivery to Sydney, $31.09 GST for a total of $341.93. Uncertain of the currency, probably USD. Non Prime member.
Have you actually purchased this product at USD $184.79 delivered and GST included?
Edit: I reckon the deal expired at 6am AEDT. Deal page now shows $299. Marked deal as expired until we can see the lower price again.
