Anyone who commutes to a big city knows how loud and distracting things can get — whether it’s the whine of a bus engine, a subway car’s ca-clank or just that screaming baby seated behind you. Some folks may find cranking jams through their headphones helpful for blocking out the world, while others would prefer a bit more relative silence. Thankfully, in this modern age there exist headphones with noise-cancelling goodness to help you zone out. Sony hasn’t been a stranger to such cans, and recently introduced its $200 MDR-NC200D noise-cancelling headphones ; a mid-range option for folks wanting similar benefits of its over-ear NC500D in an on-ear package. The claim is that these pups will reduce “98.2 percent of ambient noise” for up to 22 hours on a single AAA, so we sported the MDRs for the past few weeks as our primary set of headphones to hear for ourselves. You’ll find all of the rock blockin’ deets just after the break.
