Active Noise-cancelling Headphones, $29.95 @ Jaycar Electronics
rather than just blocking out other sounds, these kind of active headphones work by sampling the ambient sound waves and electronically mixing them out-of-phase to cancel them out...
i haven't tried these, so i can't comment on the sound quality... however, i do know that Jaycar has a good returns policy...
