Bose Sleepbuds II is a $250 earbuds that help you sleep

Bose has introduced the second generation of Sleepbuds, a pair of headphones specifically designed to help users get peaceful, uninterrupted sleep.

Unlike regular earbuds, the Sleepbuds don't play music. Instead, it plays a set of specially composed tracks designed to mask the kind of noises that can disrupt someone's sleep cycle.

Bose discontinued the first generation of the Sleepbuds because of battery issues. The new model addresses that with a new NiMH battery and features a new ultra-lightweight design with proprietary ear tips for snug fits. An expanded list of 35 tracks meant to "cover and replace" noise such as traffic, dog barking, and other late-night nuisances have been added. Each earbud is a quarter-inch deep so that side-sleepers can comfortably wear them against a pillow. There is also an "anti-friction" coating that Bose claims will prevent squeaking noise when rubbed against fabric. The buds are rated for IPX4 for water and sweat resistance.

In a press release, Steve Romine, head of Bose's health division, said "Bose Sleepbuds II use advancements in our proprietary noise-masking technology because covering sound — not cancelling it — is better for sleeping,"

Sleepbuds II will cost $250 and Bose will start shipping in early October.
