| Bottom line | While they may not be quite as comfortable as Bose's ultrapopular QC 15 headphones, the Harman Kardon NCs offer slightly better sound and have a built-in rechargeable battery to power the active noise-cancellation circuitry. | It's true that Sony's MDR-1R headphones come with a lofty price tag, but if you're searching for highly accurate-sounding headphones with style and substance, they deserve your attention. | Sure, the Beyerdynamic T90 is pricey, but no other less-expensive headphone can match the T90's combination of comfort, sound, and build quality. |
