Hear the difference for yourself

Wear QC3 headphones when you fly, and you'll notice a dramatic decrease in engine roar?the moment you turn them on. The cabin becomes more peaceful; you can hear yourself think. Use the detachable cord to connect your MP3, DVD or CD player, or to listen to the in-flight movie.With these travel headphones, you'll hear audio detail and clarity you may have never experienced before.

Wear QC3 headphones at home or at the office and notice distractions fading softly into the background. No headphones will eliminate all noise. But proprietary Bose noise reduction and audio technologies work together to make almost any listening experience more rewarding.

A choice in headphone design

Many people prefer the fit of on-ear headphones. But conventional technology can compromise the performance of smaller earcups. Bose engineers began exploring something we weren't sure was even possible: overcoming the performance limitations of smaller-sized, on-ear headphone design. The result is our QC3 on-ear headphones.

With their introduction, you finally have the option of Bose on-ear headphones that match the noise reduction and audio quality benefits of our around-ear QC2 headphones. The same level of outstanding performance. With a smaller, on-ear design.

Greater convenience and portability

 QC3 headphones fold flat for compact storage in a slim carrying case. And for added convenience, the headphones are powered by a rechargeable lithium-ion battery with approximately 25 hours of run time. Battery and wall-socket charger are included with purchase.

An optional mobile communications kit lets you use QC3 headphones with most music-enabled mobile phones. You enjoy quality audio for your phone conversations, and you can switch seamlessly between music and calls.

For over 25 years, our Acoustic Noise Cancelling® headphones and headsets have defined and led the active noise reduction headphones category. And now you can enjoy the latest advance: QuietComfort 3 headphones with on-ear design. Engineered exclusively by Bose, the most respected name in sound.
