Noise cancellation and the spatial audio trade
Bose remains the reference point for silencing an aircraft cabin, and owners rarely dispute it. Sony's cancellation is close and its adaptive features adjust more intelligently to changing environments. The catch on the Bose side is Immersive Audio, which sounds excellent on films and live recordings but hollows out vocals on ordinary stereo tracks, and cuts battery life from 24 hours to roughly 18.
Build quality over months of carrying
This is where Sony owners report the clearest problem. The XM5 does not fold, and a vocal group of daily commuters describe the hinges feeling less sturdy after months of being pushed into bags. Bose moved to cast aluminium hinges for this generation, and durability complaints are noticeably rarer. If you carry headphones loose in a rucksack every day, this should weigh on the decision.
The bottom line
Bose QuietComfort Ultra (86) edges the Sony WH-1000XM5 (82), mainly on comfort and build. Sony remains excellent and is often the better value when discounted, especially for people who mostly listen at a desk. For heavy travel, Bose is the one owners regret less.
