At a glance, you may be mistaken in thinking this speaker is just like any other Bluetooth stereo. It certainly looks the same, however it comes with an added twist: a white noise feature to help lull you into a natural sleep. The included 4GB microSD has 10 pre-loaded nature sounds that rise and fall in volume to help your mind relax at night, plus you can also use the Bluetooth connection to stream your own favourite white noise track or music.
