"I've gone through three pairs of headphones since 2019. The ANC on these is so far ahead of everything else I stopped comparing after a week. The battery just means I charge before every long trip."

"Wore them for a seven-hour flight without them getting uncomfortable once. Previous headphones I'd be adjusting every hour. These just stayed."

"Sound quality out of the box is surprisingly balanced — no EQ needed. I expected the Bose house sound to be bass-heavy, but these are cleaner than I expected."

Inability to turn ANC off is a recurring topic across SoundGuys, TechRadar, and r/headphones owner threads — buyers report feeling locked into ANC processing at all times, which they connect directly to the below-average 24-hour battery ceiling.

Battery life compared unfavourably with rivals is noted in nearly every owner comparison posted to r/headphones — the 24-hour ceiling sits below Sony XM5 (30h) and Sennheiser Momentum 4 (60h). At $599 CAD, owners expected more.

Immersive Audio is reported as polarizing on music — a consistent pattern in What Hi-Fi? and Tom's Guide reader impressions is that spatial processing makes stereo recordings sound wider but less coherent, with some owners switching it off permanently.
Source: What Hi-Fi?Owners who commute daily or work in loud open offices put the QC Ultra's ANC above everything else they've tried — the consensus in long-term impressions is that it does what it promises at a level competitors haven't matched. The comfort-to-noise-cancellation combination earns consistent praise. What owners qualify is the battery: 24 hours runs out before the most demanding multi-leg travel days, and with no way to disable ANC to stretch it, this is a real ceiling. At $599 CAD, buyers are paying a premium for the best ANC on the market.
