What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Sound quality measures well out of the box with balanced tuning, strong mids, clean bass extension, and typical Sennheiser tonality that sounds mature and exciting without heavy EQ tweaking
- Battery life exceeds 55 hours with ANC enabled, outlasting nearly all competitors and eliminating charging anxiety on long trips
- Multiple connection options including wired listening over USB-C and standard headphone jack preserve functionality across different devices
Reviewers push back
- Noise cancellation performance was dated at launch, reducing outside noise around 76 percent compared to 88 percent on stronger competitors, allowing more ambient sound through
- Touch controls sometimes fail to respond on startup until toggled off and on again in the app
- Headband padding design cannot be removed or replaced if it becomes uncomfortable during very long listening sessions
Reviewers agree the Momentum 4 Wireless delivers excellent sound quality and extraordinary battery life, though its noise cancellation trails class leaders and the design carries some functional quirks.
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 Momentum 4 Wireless: One reviewer finds the pronounced midrange sits nicely and adds maturity, while another notes it can cause struggles with heavily compressed wall-of-sound recordings 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
