Headphones 700 offer sound control that’s available only from Bose, including 11 settings that range from full noise cancelling (which helps isolate you from your surroundings) to full transparency (which helps let your surroundings in, as if you weren’t wearing headphones at all). Plus, one click triggers Conversation Mode, which simultaneously switches your headphones to full transparency and pauses your music, for a momentary break from private listening.
