Bose QuietComfort Ultra Earbuds (2nd Gen) White

The Bose 896637-0020 QuietComfort Ultra Earbuds (2nd Gen) are true wireless in-ear headphones finished in White Smoke. They combine adjustable noise cancelling with CustomTune technology that analyses ear shape to personalise audio and noise reduction. The charging case uses a USB-C port and supports wireless charging.

Listeners wanting personalised sound

These earbuds suit listeners who want high-fidelity audio tuned to their ears and Bose’s best in-ear noise cancellation with adjustable modes. Buyers who need longer continuous playtime than six hours per charge or who require a fully waterproof rating beyond IPX4 splash resistance should consider other options.

Six-hour battery life with three extra case charges

The buds deliver up to six hours of playback on a single charge, dropping to four hours with Immersive Audio enabled. The case stores three additional full charges and replenishes in two hours via USB-C or a wireless pad, defining how long you can listen away from power.

Questions about this item

How do I pair the 896637-0020 earbuds to a second device for multipoint connection?

The earbuds support seamless switching between two paired devices. Use the Bose app to manage connections and select the active source without re-pairing each time.

Which parts of the 896637-0020 kit wear out and need replacement over time?

The silicone eartips in sizes S, M, L and stability bands 1, 2, 3 degrade with daily use. Replace them when seal or comfort declines to maintain noise cancellation.

What stops the 896637-0020 from playing longer than six hours on a single charge?

The internal rechargeable battery limits continuous playback to six hours. The case adds three full recharges before it also requires a two-hour wired or wireless top-up.
