You wanted wireless QuietComfort headphones. So we re-engineered them with Bluetooth® technology and our world-class noise cancellation that makes quiet sound quieter and music sound better. So you can just listen. With nothing in the way. You feel it at the flip of a switch—noise fades, and your music soars. That’s the power of our Acoustic Noise Cancelling technology, which continuously measures, compares and reacts to outside noise—then cancels them with the opposite signal. In recognition of the holidays, we’re now offering QC35 headphones in a bold, blue finish. There are limited quantities of this new color, and once they’re gone, they’re gone. So don’t wait to get this unique look for our best headphones yet. Enjoy up to 20 hours of listening, enough time to pour through this entire playlist. And when it finally runs down, a quick 15-minute charge gives you another 2.5 hours. Materials matter. That’s why the QC35 headband isn’t just soft, it’s luxurious. Wrapped in Alcantara®—the soft covering material used by prestigious international companies in various applications, like yachts and high-end automobiles—it provides a welcome comfort designed for all-day listening. The ear cushions are manufactured from a synthetic protein leather, and have a silicone bead for passive noise reduction.
