Bose® QuietComfort® 20i headphones are the first in-ear noise cancelling model from Bose. They let you enjoy better sound from your iPhone, iPad, and iPod every day, everywhere you go. Shut out the world and lose yourself in your music—or let the world in. It's your choice. Turn on noise cancelling to reduce surrounding distractions and focus on your music, or choose Aware mode to continue enjoying your music while also hearing what's around you.
