Bose QuietComfort 20 Acoustic Noise-Cancelling In-Ear Headphones

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.

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.
