About this item Legendary sound. Personalized to you -Your music sounds best when the listening experience is tailored to you. That's why Bose QuietComfort Earbuds II are engineered with pioneering CustomTune sound calibration technology that optimizes the noise cancellation and sound performance to fit your ears. The best noise cancellation of any earbud or headphone - QC Earbuds II represent a revolutionary advance in noise cancellation technology with the ability to cancel noise better than any noise-cancelling earbuds or over-ear headphones on the market. It starts with ensuring an optimal fit to your ears. The soft, silicone ear tips have an umbrella shape that creates a firm seal at the opening of your ear, reducing outside noises. Microphones then detect environmental noise and generate an opposing signal to cancel it, making your quiet sound quieter. You and your music in perfect sync - QuietComfort Earbuds II deliver lifelike, balanced sound with nuance, clarity, and depth, so you can get in the zone and feel seamlessly connected to your music. The wireless earbuds are engineered with high-performance drivers, amplifiers, and electronics that are custom-designed to fit a small package. Find your best fit with the Bose Fit Kit - To ensure your wireless earbuds feel comfortable and stay put no matter what you're doing, QC Earbuds II come with a Bose Fit Kit. The convenient Fit Kit includes three pairs of ear tips and three pairs of stability bands designed to fit the unique shape of your ears. Both the ear tips and stability bands are made from soft silicone for all-day comfort and a secure fit. The ear tips rest gently but securely in your ears and spread contact evenly. You're in control of your sound - With Bose QC Earbuds II, you decide how much of the world you want to hear. Quiet Mode offers maximum noise cancellation, so you can feel fully immersed in your music. Want to listen to music but still hear what's going on around you? Aware Mode offers full transparency to hear your surroundings with striking clarity. This mode automatically applies ActiveSense technology to soften the loudest sounds, like a passing bus, to a more pleasant and balanced volume.
