Headphones 700 feature a revolutionary microphone system that’s unlike any other headphones, with game-changing voice pickup engineered for making and 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 and then by suppressing the most disruptive remaining sound around you. It all happens in real-time and adapts as you — or the source of the noise — moves.
