　　When it comes to noise cancelling headphones，sometimes the best offense is a good defense.While there are plenty of active noise cancelling headphones that use a complex(and pricey)method to block distracting sounds，there are simpler ways.How about headphones with a snug fit that simply plug up your ear canals?

　　This process is called passive isolation.It’s not uncommon for a consumer faced with the choice between the descriptors“passive”and“active”to choose the stronger-sounding technology,but great passive isolation can be just as effective and cost a lot less.

　　The K323 XS really shines.even in a crowded market.It’s hard to pick which glowing attribute to praise first：The massive，well.balanced sound stage?The distortion.free listening experience?The$59 price tag?The monster isolation?The tiny,portable design?These AKGs are simply aces(王牌)，and online sale prices of around$40 kick everything up another notch(等级).
