Bose Noise Cancelling Headphones 700 reinvent what true wireless headphones are—and redefine what they can be. Nothing comes between you & your music The patented active noise cancelling technology in Headphones 700 uses microphones both inside & outside the earcups to monitor the sounds around you & instantly produce an opposite signal to cancel them out creating an empty stage for your music to play on. At the same time our proprietary Tri Port acoustic headphone structure uses external ports to vent the earcups & maximise the acoustic space inside giving your music depth & detail. Hear what you want not what you don’t.. . 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 & pauses your music for a momentary break from private listening. Crystal clear calls. For you & them.. . Headphones 700 feature a revolutionary microphone system that’s unlike any other headphones with game-changing voice pickup engineered for making & taking calls in less-than-ideal conditions. Six mics work together to cancel the noise around you so you can hear the caller better while four mics combine to improve the clarity of your voice so the caller can hear you better first by isolating your speech & then by suppressing the most disruptive remaining sound around you. It all happens in real time & adapts as you—or the source of the noise—moves. THEY FEEL AS GOOD AS THEY LOOKEven though we’ve been making noise cancelling headphones for decades for Headphones 700 we began with a clean slate. The result? A head-turning new form factor designed for all-day everyday use. Earcups tilted at 15 degrees to mirror the anatomy of the human head & ears. Ear cushions made from plush protein leather for long listening sessions. A streamlined steel headband tuned to clamp securely but not uncomfortably & an underside of soft silicone-covered foam. & so much more. Speak swipe or tap.
