Bose invented the consumer noise-canceling headphone category and spent decades as its undisputed leader. The QuietComfort line has been the traveling professional’s companion of choice for generations, and each iteration has refined the formula. The QuietComfort 45 continues this tradition while facing the most competitive market Bose has ever encountered, with Sony, Apple, and Anker all delivering serious competition at various price points. After extensive travel use across multiple long-haul flights, here is our assessment of whether the QC45 still earns its place in the traveler’s bag.
The most immediately striking thing about the QuietComfort 45 is how comfortable they are. Bose has refined the ear cup design across decades of iterations, and the QC45 achieves a cushioning and clamping force balance that allows extended wear without discomfort. The ear cups rotate to fold flat, and the included hard case is compact enough to fit in the top compartment of most carry-on backpacks. For travelers who wear headphones for six to fourteen hour flights, the comfort advantage over firmer competitors is genuinely meaningful.
Noise cancellation performance is excellent, though the crown has passed to Sony’s WH-1000XM5 as the benchmark in the category. The QC45 handles low-frequency rumble like airplane engines and air conditioning exceptionally well, which is exactly the noise profile that matters most for travel. Where it falls slightly behind the Sony is in handling mid-frequency noise like conversations and keyboard clicks. For the specific use case of airplane travel, the QC45’s noise cancellation is entirely satisfying and noticeably better than budget alternatives.

Sound quality reflects Bose’s signature warm, balanced tuning. The bass is present and satisfying without being overwhelming, the midrange is clear and natural, and the high frequencies extend smoothly without harshness. The sound is immediately enjoyable across all music genres, and while not as analytically detailed as some competitors, it’s more consistently pleasant for extended listening. This characteristic has always made Bose headphones immediately accessible and popular regardless of the listener’s audiophile inclinations.

Battery life is rated at 24 hours, which provides adequate coverage for even the longest travel days including a full transpacific flight plus some ground time on either end. A USB-C quick charge provides three hours of playback from 15 minutes of charging, which is genuinely useful when you’ve forgotten to charge before departure. The headphones can also be used passively with the included 3.5mm cable when battery depletes.

The Aware Mode — Bose’s transparency mode that pipes in ambient audio — is one of the most natural-sounding implementations available. It sounds significantly less processed than many competing transparency modes, making it genuinely useful for conversations at the gate, listening to announcements, and navigating airports without removing the headphones. The transition between Active mode and Aware mode is instantaneous via a single button press.

Call quality is good but not exceptional. The microphone system captures voice clearly in moderate noise environments, but in very loud settings like busy airports, callers report the background noise is more audible than it would be with the Sony XM5 or Apple AirPods Max. For the occasional call during travel, it’s perfectly functional. For those who spend significant time on calls, the Sony or dedicated call headsets may be more appropriate choices.
Our verdict: the Bose QuietComfort 45 remains a genuinely excellent travel headphone that prioritizes the right things for the traveling use case. The comfort is class-leading, the noise cancellation is excellent for airplane use, the sound is immediately enjoyable, and the 24-hour battery handles the longest travel days. The Sony WH-1000XM5 has edged ahead on noise cancellation and audio precision, but for travelers who prioritize comfort above all else, or who find the Sony’s sound signature too analytical, the QC45 remains a compelling and competitive choice.
