Last year, Bose took to Indiegogo to gauge people's interest on an experimental device: a pair of noise-masking wireless earbuds designed to help you sleep. That experiment was a success, and the "sleepbuds" sold out within six days on the crowdfunding platform, so now the audio giant is making them available for purchase. These sleepbuds were designed to fit snugly -- they're apparently Bose's smallest products yet --allowing you to drift off to sleep without the feeling that there's something in your ears. In addition to blocking noise, they come with 10 pre-loaded white noise tracks that mimic snoring, the sound of gentle waves, dogs, traffic and wind turbines, among other things. What they don't do, however, is stream music.
