QuietComfort 25 headphones are re-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. Bose completely redesigned their industry-leading headphones, with higher-quality materials and finishes. They're lightweight, and ear cups 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 ear cups pivot to fit in a compact case that's easy to carry. QC25 headphones let you focus on what matters-your music, movies and videos. And block out what you don't want to hear. Like a crowded city street. Advanced noise reduction technology and unique electronics make it happen. Even the ear cushions give you an extra level of quiet by sealing out the world around you. Many Bose engineers are also musicians, with a passion for music. So when you wear these headphones, you'll hear ringing guitars. Soaring vocals as the chorus kicks in. Deep bass and crisp drums drive the beat forward. Bose Active EQ and TriPort technology deliver performance so compelling, you'll want to listen for hours. And the fit's designed so you can. Bose noise cancelling headphones are designed specifically for use with your iPhone and other Apple products, so the inline microphone/remote puts music and call controls at your fingertips. Many features are also compatible with today's most popular phones. Included: QuietComfort 25 headphones, 56 inch QC25 inline remote and microphone cable, Airline adapter, Carry case and a AAA battery.
