I ended up getting mine via ebay UK as they were way too pricey in Aus and I couldn't find them in NZ.
Highly recommend them, totally worth the $$$. Great call quality, soooo comfortable (which is important when you work from home and have got them on a few hours a day) and the noise reduction is just crazy. I even wear them when I'm driving the 50mins into town - you wouldn't believe the amount of noise your car makes and how refreshed you feel without hearing that constant noise. Obviously ditto for planes. Oh, and battery life is great too, lasted well over 20 hours with noise reduction on during an NZ-Sweden trip. As wired headphones they're very accurate, and definitely not a hi-fi sounding set, which I prefer. If your source sounds great, the these headphones won't disappoint.
