What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Best-in-class active noise cancellation that muffles mid-range frequencies and voices effectively
- Exceptionally comfortable for long wear with lightweight build and folding hinges
- Superior call quality with four-microphone array that filters background noise during speech
Reviewers push back
- Three-band equalizer in the app is too limited to fix tuning problems
- Bluetooth 5.1 with only SBC and AAC codecs offers no future-proofing or higher-bitrate options
- Sound signature varies between the QC45 and newer QuietComfort model, with excessive bass and treble peaks in the refresh
“the qc45 is arguably the most comfortable pair of overear headphones out there”
Where reviewers split on QuietComfort 45: Sound quality divides reviewers—some find it balanced and pleasant, others criticize pronounced bass and harsh highs between 6-8kHz that are hard to equalize away
