The Noise Cancelling Headphones 700 are an upgraded version of Bose’s celebrated QC35 IIs, which essentially set the benchmark for premium noise-cancelling headphones. If you’re not familiar with noise-cancelling headphones, they work by using active noise cancelling (ANC) technology and tiny exterior microphones to cancel out external sound frequencies, delivering super crisp audio. There are some major differences between these and the QC35 IIs, mainly the number of noise cancellation levels. The QC35s only had three noise-cancelling options, but the 700s have a massive selection of 11, giving you more choice when it comes to the frequency ranges you want to cancel out, ultimately making the headphones more effective. Like the QC35 IIs, they’ve got a strong Bluetooth connection, are optimized for a decent selection of voice assistants such as Alexa and Google Assistant, and have a battery life of up to 20 hours. Once they start running low, just charge them back up using the USB C cable that comes included. Touch controls make it easy to multi-task too, whether that’s switching between calls or searching for new tracks on Spotify. You’ll need to download the Bose app onto your mobile in order to use the headphones properly and toggle with the settings, but all-in-all these are incredibly simple to set up. If you work in a busy office and want to say goodbye to those audio distractions around you - colleagues chatting, doors slamming shut and the sound of traffic outdoors - you want a pair of these.
