PRODUCT OVERVIEWBose Noise Cancelling Headphones 700 deliver everything you expect from Bluetooth headphones – some things you never imagined possible. It’s no surprise PC Magazine called them “The best active noise cancellation you can buy.” Eleven levels of noise cancellation feature a range of options to choose from. You can totally eliminate distractions or minimize noise canceling to hear everything around you. Or choose from nine other levels in between. Active noise canceling technology in Bose Headphones 700 monitors the sounds around you and instantly cancels out unwanted noise to let your music shine through. At the same time, the acoustic space inside the earcups is maximized to give your music depth and detail. With these noise-canceling headphones, it’s not just your music that’s clear, so are your calls. The unrivaled microphone system uses a series of microphones to adapt in real-time to noisy and windy environments so voices sound crystal clear on calls. Voice commands are also captured with unprecedented accuracy. The stunning new design of Bose Headphones 700 features a streamlined stainless-steel headband and a lightweight, comfortable fit that’s perfect for all-day listening.KEY FEATURESAstonishing sound: Crisp, clear details.
