Lose yourself in your music

QC20 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
reduces 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.  

Engaging sound

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 cone 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 and call answer/end buttons. The 2-button remote (QC20 model)
is designed for your Android, BlackBerry or Windows phone. The 4-button remote (QC20i model), customized for
use with your iPhone or iPod, adds volume, music control and voice commands.

Rechargeable battery

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 similar to that of our
regular in-ear headphones.

When not in use, simply store your headphones and cables
in the included carrying case.
