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. 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. The subtle details shine through, too. So wherever you are, your music's front and center. The 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.
