The Bose Noise Cancelling Headphones 700 UC are designed to give you better conference calls. While both Headphones 700 and Headphones 700 UC utilise the same adaptive eight-microphone system, 11 levels of noise cancellation and astonishing sound, the UC version features the added benefit of the pre-paired Bose USB Link Bluetooth module and certification for use with Microsoft Teams and Google Meet. The USB Link allows users to stay reliably connected to their computer and to easily toggle between computer and mobile phone.
