Muji's known for its ultra-minimalistic take on everything from office supplies, to apparel, to electronics like this simple splash-proof speaker housing for a smartphone that still provides full access to its touchscreen.

Powered by three AAA batteries that promise up to 30 hours of playback, the $70 speaker eschews a wireless connection to your device in favor of an old school tethered connection to its headphone jack. A series of heavy duty clamps keep any and all moisture out, while a flexible membrane that wraps across your phone's display like cellophane still lets you view and use its touchscreen for playback control.

Shown with an iPhone 4 under the hood, the speaker's generous capacity looks like it can handle almost any reasonably-sized smartphone or media player, although the Galaxy Note could be pushing its limits.
