The best noise cancellation of any earbud 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. CustomTune technology personalizes the noise cancellation to the shape of your ears to precisely soften sounds that are hardest to reduce, like voices. 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. CustomTune technology takes the sound to the next level by personalizing it to your ears, so your music sounds even more immersive and emotionally impactful. 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. The stability bands hug the contours of your ears with curved fins that grip your ears for a snug fit. And since no two ears are the same, even on the same person, swap different-sized ear tips and bands to find your best fit. 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. Use the Bose Music app to disable ActiveSense or create custom noise cancellation modes. Crystal-clear, natural-sounding phone calls Use Bose QC Earbuds II to enjoy clear and natural-sounding phone conversations. Two noise-rejecting microphones in each earbud focus on the sound of your voice and filter out ambient noise and wind. Digital signal processing technology further enhances the signal to ensure your conversation is clear. Calls play through both earbuds, or you can use either bud by itself.
