Bose QuietComfort Ultra

The 101 user comments come overwhelmingly from a Lemmy thread asking for ANC recommendations, so Bose-specific signal is thin. Much of the thread is generic ANC education (a +5 comment explains active vs passive cancellation and notes most ANC implementations only target specific frequency bands), running jokes about the African National Congress, and recommendations for OTHER products: Fairphone Fairbuds (+6, praised as eco-friendly), Sony XM4/XM5 (with a +4 tip that upsizing ear cushions fixed weak ANC on Sony buds), AirPods Pro, wired Shure SE215 IEMs paired with a Qudelix 5K on the 94dB NYC subway, plus rtings.com and scarbir.com as measurement sources. The strongest Bose-specific data point is a direct owner A/B [+3]: 'I've actually compared XM5 and Bose Ultra and Sony's ANC was like 30% of Bose's. That much worse, which surprised me.' Another commenter said rtings' measurement data drove their choice of Bose, while asking whether a competing flagship ANC release was imminent. CAUTION ON ATTRIBUTION: one comment reading 'their audio quality and anc is worse than competition noticeably. So its quality vs environment' sits inside the Fairbuds recommendation thread and most plausibly refers to Fairphone, not Bose; I flag it as ambiguous rather than scoring it against Bose. No Bose owner in this layer reports battery, reliability, or app issues — the layer simply lacks that depth. Data caveat: comments are heavily duplicated in this export (most appear twice), so the effective unique sample is roughly half of 101, and almost none of it is Bose owner testimony.
