Fixed the link. Apologise - opening several Amazon's deal and camel3x tabs and copied wrong link :(.
Saw this headphones on sale recently, and it is back on sale for $395 (RRP $625, 37% off). Not as cheap as the one sold by other seller (posted here recently), but this is Amazon AU all time low based on camel3x.
Only black available for that price.
