$105 for Audio Technica Headphones from Amazon
I've heard that Audio Technica Headphones are great although some people have said that its bass seems a bit weaker than other headphones. That said, I immediately bought a pair from Amazon for $105, and shipping is even included. The last time these were available to be shipped to Australia through Amazon was about 12 months ago so I just grabbed it as soon as I saw the item. You might have some issues with Amazon's exchange rate so you could just pay for it with US dollars and pay a foreign transaction fee with your bank. You should really take advantage of this while there are supplies because this doesn't pop up there often.
