Better sound begins with better silence. That’s why Bose engineered QuietComfort® Earbuds with the world’s most effective noise cancelling and high-fidelity audio, plus StayHear™ Max eartips for extra comfort. It starts with soft, silicone tips that passively block some noise. The true quiet comes from our proprietary Acoustic Noise Cancelling™ technology. Tiny, powerful microphones hidden in the earbuds monitor environmental sounds and then produce the opposite signal, cancelling out unwanted noise. A custom acoustic architecture and Bose innovations like volume-optimised Active EQ keep your music clear and balanced at any volume. While your voice sounds clear on calls thanks to microphones that work together to filter out noise and wind around you. The eartips provide comfort, stability and passive noise blocking, with three sizes included. Listen for up to 6 hours on a single charge, and get 2 additional full charges from the included case. And with an IPX4 rating for sweat and weather resistance, these earbuds are built for durability. Available in Triple Black, Soapstone and limited-edition Stone Blue.
