Upgrade your music experience with the Bose QuietComfort 45 noise-canceling headphones. Designed to replace the brand’s QuietComfort 35 II, these over-ear headphones deliver simple controls and, of course, amazing audio performance. In particular, the earcups add depth and fullness with a smaller, lightweight design. Also, Volume-optimized Active EQ maintains highs and lows for consistent sound, no matter the volume. They offer a 24-hour battery life and synthetic leather on the earcups for long-lasting comfort. Moreover, the Bose QuietComfort 45 sport improved voice isolation for clearer conversations in noisy environments. And the built-in noise-rejecting algorithm filters out background noise and windy conditions in real time. Boasting 2 listening modes—Aware and Quiet—you can adapt these plush headphones to your environment. For example, enjoy music and podcasts in a busy office space with excellent clarity and detail without any distractions. Or switch to full transparency to let the world back into your ears.
