Lose yourself in your music
QC20i headphones let you experience music on the go as never before. You'll enjoy lifelike, digital sound quality that stands out from the noise around you—plus the freedom of an in-ear headphone. StayHear+ tips physically block some noise while our Acoustic Noise Cancelling technology electronically reducesreduces most of what's left. It's just you and your music, even in noisy environments.
Tune in to your environment
But there are moments when you may not want to be so cut off from your surroundings. Crossing a city street. Waiting for airline gate announcements. This is where Aware mode comes in. Instead of removing your headphones, just press a button, and you're back in touch with the sounds around you—while your music keeps playing, and you still experience some noise cancellation.
All this, plus Bose lifelike sound. Sound you wouldn't expect from in-ear headphones. Our TriPort™ technology and Active EQ combine to give your music a depth and balance that keep your daily soundtrack fresh and alive. The subtle details shine through, too. So wherever you are, your music's front and center.
Advanced ear tip technology
And your music's even easier to enjoy when you're not fussing with your headphones. Proprietary StayHear+ tips create a soft, secure fit with no need to force them into your ears. The mushroom shape spreads contact evenly across the ear for maximum comfort, and forms a gentle seal that contributes to the headphones' full-spectrum noise reduction.
You're in control
Controls are all at your fingertips. Use the slider switch on the control module to turn noise cancelling on and off. The inline remote/microphone houses Aware mode, call answer/end and volume buttons. The 4-button remote, customized for use with your iPhone or iPod, adds music control and voice commands.
The environmentally friendly built-in lithium-ion battery (located inside the module) charges in just 2 hours with the included USB cable, and delivers up to 16 hours playing time per charge. A battery indicator light displays power status. And, even if the battery dies your music still plays with performance equal to that of our regular in-ear headphones.
