based on your budget, i don't know what to recommend.
if the AU$ was stronger, i'd have recommended the Etymotic ER-6i
they'd have worked out to be about AU$120+ and they're pretty damn goood.
i've got a pair.

otherwise, i don't know about earphones with long cables and decent bass.

you can just get some cheap Sennheisers or Sonys, i guess.
