What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Bose QuietComfort Ultra Earbuds (2nd Gen)
Two whitelisted outlets (SoundGuys, What Hi-Fi) both hands-on tested these and rate them a strong premium pick at an unchanged $299 / £299: class-leading noise cancelling and a comfortable, secure fit via Bose's stability bands. SoundGuys measured 85% external-noise reduction and a below-average 5h34m battery, and knocks the poor 3-band EQ. Verdicts split on sound: What Hi-Fi awards five stars for richer, punchier tuning, while SoundGuys' reviewer personally dislikes the bass/treble-heavy signature and calls the refresh minor enough to just buy the cheaper 1st-gen on sale. (2 sourced reviews, 2 lab-tested.)
Praised: Class-leading active noise cancellation; Comfortable, secure fit aided by stability bands; No price increase, still $299 / £299.
Flagged: Battery is a relative weak point (below average per SoundGuys; heavily drained by Immersive Audio per What Hi-Fi); Minor, iterative upgrade over the 1st-gen buds; Poor, limited 3-band EQ tuning options.
