Sennheiser PXC550, RRP $629.00, Now $398 with Free Freight @ Addicted to Audio
JB HiFi price matched as Addicted to Audio have a bricks & mortar store :D
Picked these up over the Sony MDX 1000x after trying them on and thought the control mechanism was appealing. Also you can disable the noise cancelling, unlike the QC35's. I was also kind of spooked by the MDX-1000x cracking headband issue.
Yes the specs on the MDX indicate a better sampling rate, but the difference was negligible after A/B testing. It's also hard to come by music beyond 44.1k sample rate (that I actually want to listen to).
Just a warning, I've tried to price match at the Melbourne CBD store before and they only price match with shops within the same post code.
