We made considerable improvements in Bose Sleepbuds™ II:

Sleepbuds™ II use nickel-metal hydride (NiMH) battery technology, which has a 30-year history of use in both consumer and medical products. The earbuds have battery life of up to 10 hours. Although less than the 16 hours of the original noise-masking sleepbuds™, this is still enough for a full night’s sleep.



Further, the storage case can recharge the buds three times, providing a total of up to 40 hours of use versus 32 for the original Sleepbuds™.

Noise-masking capabilities are improved through a change in the bud design, which led to better passive blocking of noise, as well as further optimization of masking sounds around a new, better-performing driver.

An expanded content library includes more options for noise-masking and relaxation with the addition of nature sounds and soothing music. More content will be added through future software updates.

Connecting the buds to the app is more reliable. It is also easier to consistently place the buds in the case correctly, thanks to a repositioning of the magnets on the buds and a design tweak to how they align within the case.

The addition of an anti-friction surface is designed to avoid any noise made when the earbuds are rubbed against a pillow.

We are committed to continually adding new features and content over time.
