Swanky and well-engineered, Harman Kardon’s retro-inspired sound cans are the freshest-looking and most impressive pair of noise cancellers on the scene. The appropriately tagged NC’s match the soundstage and refine audio output of the Bose QC 15, though carrying a built-in rechargeable battery that gets 40 hours of playback. It's even functional when vitality is drained. NC might have just took on a whole new definition: No competition.
