The Bose QuietComfort 45 are the upper echelon of noise-cancelling headphones. If you want the best in audio wearables, this deal is for you. Bose’s QuietComfort 45 headphones are among the best noise-cancelling headphones out there. These excellent noise blockers pack 45mm drivers, high-fidelity sound and up to 24 hours of battery life. Aware Mode lets you hear what’s going on around you right through the headphones. In our Bose QuietComfort 45 review, we praise their fantastic sound, excellent noise- cancellation and comfortable fit. We gave the Bose QuietComfort 45 headphones a high rating of 4 out of 5 stars — backed by our Editor’s Choice award. By design, Bose QuietComfort 45 headphones are nearly identical to the previous-gen QuietComfort 35 II model. They retain the same plastic, over-ear design with plush synthetic leather memory foam ear cushions. Our reviewer wore them for an entire workday with no discomfort. During real-world testing, audio was clear and balanced as was call quality. In terms of noise-cancellation, the headphones did a great job at blocking ambient sound. At 8.5 ounces and 7.3 x 3 x 6 inches dimensions-wise the Bose QC 45 weighs less than competing headphones. By comparison, the AirPods Pro Max (13.6 ounces, 7.4 x 6.6 x 3.3 inches) and Sony WH-1000XM4 (8.9 ounces, 9.9 x 3 x 7.3 inches) are heavier. If you want to own the best headphones money can buy, the Bose QuietComfort 45s are a wise choice.
