Moving on to the most important part, Noise-Cancelling. From my test, the Sony WH-1000XM3 managed to successfully beat the Bose Noise Cancelling Headphones 700 by a little. Sony's feature Adaptive Sound Control allows for toggling of different noise-cancelling modes like Walking, Staying, Transport and Running. Each has different levels of noise-cancelling and ambient sound mode. These are all automatically detected by the headphone itself. Users can toggle the amount of ambient sound let in, focus on voice only or just turn it off completely. Atmospheric Pressure Optimizing is another feature that helps to optimize the noise-cancelling to fit different environments such as in an aeroplane or on the ground. In the end, these features managed to defeat the noise-cancelling abilities of the Bose which only allows for a fixed ambient sound mode through its levels 0 to 10 adjustments. So, the SONY WH-1000XM3 wins this round again.
