All the reviews that I've read seem to suggest price is a key indicator of quality of noise canceling ability.

if they do not have to be headphones then the in ear units like the Shure and Koss units cut even quite loud back ground external noise to very negligible amounts ...

how ever I am a cheap-skate and instead did this.....
for a way to save on the $300+ for the Shure and $100 for the Koss buy the Apple "in ear' ones for around $60 then ditch (or at least don't fit) the useless supplied silicon rubber ear pads. Next go to a hardware shop (the DIY type not the computer type) and buy a few pairs of tapered in ear foam hearing protection plugs (the ones that look a bit like the teat on a small baby's dummy or feeding bottle) - cut 2 in half ( front to back not length ways) and spike the back half it on a small (jewellers) screw driver then "gently force" it on to the projecting "in ear" part of the bud. don't worry that the foam projects a little past the driver on the ear bud as when you insert them in to your ear that will be pushed back exposing the driver.... To insert squish the foam for a few seconds then push in to ear and hold for a a few seconds while the foam expands - great bass response and almost zero background noise - once you get used to them - you may want to take them out every hour or so until you do - you can find your self sleeping 8 hours with them in - great for that red eye flight

 Can anyone recommend where I can buy some noise-cancelling headphones in
 Perth that:

 A) do a good job
 B) don't cost the earth  (eg Boss and Sennheiser!)
 C) can pick up before cob Friday

Pick any two...

Unfortunately if you want them to do a good job, they do cost the earth.
