Are your earphone cables always in auto-tangle mode? Here's a good idea from designer Jaehyung Hong: a Bluetooth lanyard with transport controls on board, letting you control your MP3 player while you're listening, and then store your earphones in its handy slot when you're not. Roll those messy cables up inside the device, keeping that spaghetti bowl of wires from tangling up so much. Neat. [Yanko Design]
