What reviewers say about the Bose QuietComfort 45
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.

Where reviewers disagree 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.

Battery life, ANC on (constant output of music peaking 75dB(SPL) until depletion): 24 hours 49 minutes
The Bose QuietComfort 45 does an excellent job of canceling outside noise with its updated ANC system.
With noise canceling on, the Bose QuietComfort 45 lasts 24 hours 49 minutes, surpassing Bose’s official 24-hour battery life for the headset.
A lot of our gripes with the headset have to do with an overemphasized high-end relative to our preference curve in its out-of-the-box tuning.
If you simply want extraneous noise nixed in the office, we give the new Bose QC45 the edge over their Sony rivals.
The QC45 have solid noise cancellation, but they're bettered in sound quality by the class leaders
Sonically, your money can buy better.
Wireless range (hands-on): 50 feet · Battery remaining after 3 days x 5 h playback, ANC on: 40 percent
The $329 Bose QuietComfort 45 is an excellent upgrade with enhanced ANC, sound, and battery life.
ANC is top of the line, eliminating close to 90 percent of ambient noises.
the noise-rejecting mic system struggles with wind and whisking effects.
