Sony's MDR-NC22(JE) noise-canceling earphones might be able to get you some peace and quiet, and if what Sony says is true, they're able to take 75% of all that ambient noise out of your life. It's an apparently potent package, powered by one AAA battery that gives you 50 hours of running time. Sony says the thing is 39% smaller than its predecessor, too.
Just sticking earphones in your ears will reduce that ambient noise considerably, but if these babies really can cut out 75% of that cacophonous din that is everyday life in the big city, sign us up. The phones are set for a Japan rollout, but if they're as quiet as Sony says they are, we should be seeing them stateside before too long.
