Using a combination of patented active and passive noise cancellation innovations, Bose QuietComfort Earbuds feature all the noise cancelling performance of our best over-ear headphones from a compact, truly wireless earbud. 

ACTIVE NOISE CANCELLING: Internal and external microphones monitor sounds 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. sing a combination of patented active and passive noise cancellation innovations, Bose QuietComfort Earbuds feature all the noise cancelling performance of our best over-ear headphones from a compact, truly wireless earbud.
