Make every song count with these Bose QuietComfort Ultra (2nd Gen) earbuds. Bose Immersive Audio adds depth and space to your tunes so they feel more real. It is like standing right in the acoustic sweet spot at a gig. CustomTune technology analyses your ears and tailors the sound and active noise cancelling to their unique shape. Just like having your own personal sound guy following you around. And the umbrella shaped tips seal off your ear canal, reducing outside noise for better focus. Perfect for busy city life. You can choose how much of the world you want to let in with Quiet Mode, Aware Mode and Immersion Mode. The stability bands hug the contours of your ears for a comfortable fit that will not quit. Noise-rejecting microphones and AI-based noise suppression make your calls crystal clear. Take calls on either a single earbud or both, depending on your preference and situation. The IPX4 rating means they are not afraid of a little water or sweat - perfect when you are working out. Bluetooth multipoint lets you switch between devices without any interruptions or delays. With quick charge, you can get an extra two hours of battery from just 20 minutes charging.
