The World's Most Effective Nosie Cancelling Earbuds - Using a combination of patented active and passive noise cancellation innovations, Bose QuietComfort® Earbuds feature all the noise cancelling performance of their best over-ear headphones - from a compact, truly wireless earbud.

Active Noise Cancelling - Internal and external microphones monitor sound in your environment and in your ear canal and - in a fraction of a millisecond - produce an opposite signal to cancel out unwanted noise. All that's left is what you want to hear.

Passive Noise Cancelling - A soft ear nozzle is designed to conform completely to the contours of your ear, creating a gentle seal. The more airtight the seal, the less outside noise gets in, and the more you can enjoy your content. A good seal is also critically important for deep low notes, because they add more impact and emotion to your music and videos.
