Headphones on. World off.

QuietComfort® 25 headphones are engineered to sound better, be more comfortable and easier to take with you. Put them on, and suddenly everything changes. Your music is deep, powerful and balanced, and so quiet that every note sounds clearer. Even air travel becomes enjoyable, as engine roar gently fades away. No matter how noisy the world is, it's just you and your music—or simply peace and quiet.

Better by design
We've designed our industry-leading headphones with higher-quality materials and finishes. They're lightweight, and earcups rotate even more for a better fit. The headband sits closer to your head, with luxurious suede-like material underneath for extra comfort. If the AAA battery runs out, you can still enjoy music without noise reduction. And the earcups pivot to fit in a compact case that's easy to carry.
