Bose QuietComfort Ultra USB-C Black
Score: 76/100Rankings
The Bose QuietComfort 45 are over-ear wireless headphones offering industry-leading active noise cancellation and up to 22 hours of battery life with ANC on. They fall short on high-resolution Bluetooth codecs and have a heavier feel than advertised. Ideal for travelers and office workers who prioritize ANC and comfort.
The Bose QuietComfort Ultra earbuds deliver AI-enhanced active noise cancellation with CustomTune personalization and support aptX Adaptive over Bluetooth 5.3. Their battery life is limited to six hours (four with spatial audio) and the case is made of plastic. Best suited for commuters and active users seeking premium ANC in a true-wireless form factor.

Products in the top-left offer the best value (high score, low price).
Professional reviewers commend the QC45 for its best-in-class ANC, lightweight comfort, solid build quality, and convenient USB-C charging, while noting that its sound signature is merely average and it lacks high-resolution Bluetooth codecs, keeping it a step behind the very top-tier competitors.
Everyday users overwhelmingly praise the headphones for being very light, comfortable for long periods, and effective at cancelling noise during travel, but they frequently mention that the packaged weight feels heavier than expected and that the audio quality is only average, with a desire for better codec support.
“Very light”
Professional reviewers consider the 2nd Gen QuietComfort Ultra earbuds a solid evolution of Bose's flagship wireless line, applauding the AI-driven CustomTune personalization and the class-leading ANC, while noting that the battery penalty of Immersive Audio and the modest codec selection keep the product from being a clear market leader.
The source material does not provide direct user reviews, but the emphasis on multiple eartip sizes, stability bands, and the Bose app suggests the design aims to address common consumer concerns about fit, comfort, and personalization.
