## What reviewers say

Across three whitelisted testers (SoundGuys, What Hi-Fi?, Tom's Guide), the QC45 is a comfortable, long-battery pair whose active noise cancellation is consistently rated class-leading. All three praise the ANC and the 24-hour(-plus) battery, and all three note there is no true ANC-off (only Quiet and Aware modes). Two of the three also flag a comparatively sparse feature set versus the Bose 700 and the absence of aptX. Verdicts split sharply on sound quality and on call quality. (Based on 3 reviews, 2 lab-tested, 2023-09-15–2025-08-05.)

Praised: Class-leading active noise cancellation; Comfortable build; 24-hour battery life (SoundGuys measured 24 hours 49 minutes); USB-C charging replaces the old micro-USB.
Flagged: No true ANC-off; only Quiet and Aware modes; Comparatively sparse feature set, no customizable EQ, fewer features than the Bose 700; SBC/AAC only, no aptX; Call quality dips in wind.
Disagreement: Sound quality splits the panel: Tom's Guide calls it an 'excellent upgrade' with a refined sound signature and punchier, richer bass, while SoundGuys' bottom line is that sound quality 'isn't all that great' (overemphasized highs) and What Hi-Fi finds it beaten for dynamics and timing by the Sony class leaders. Call quality also splits: What Hi-Fi praised voice pickup as clear and 'virtually devoid of any passing car noise,' whereas Tom's Guide found the noise-rejecting mic struggles in wind. Reviews also disagree on EQ: What Hi-Fi and Tom's Guide report no EQ, but SoundGuys' 2025-updated review notes an in-app EQ was added by firmware.
