White noise machines that texture the silence of a quiet bedroom can actually do wonders to help ease some people to sleep. There are plenty already on the market already, but one way to stand out is with a really good design.

Enter the 'LectroFan Micro 2, newly released from California-based company ASTI (Adaptive Sound Technologies). It's a tiny little bedside speaker with a nifty top that twists upward into a vertical stance, directing any one of its 11 white noise settings in your general direction. Unplug its Micro-USB power cable and it'll run for up to 40 hours before needing a charge (make that 20 hours if you turn on its Bluetooth radio and connect it with your phone to play music or podcasts).
